Laser micro-machining technique plays an important role in semiconductor material processing

Semiconductor material likes chip and integrated circuit board are key to develop 5G technology, micro-electronics, high-speed communication, smart automobile, high-end manufacturing and so on. It is closely related to the development of a country. Therefore, in the coming future, the demand of semiconductor material will continue to grow. To meet the manufacturing demand, the semiconductor processing equipment will experience a dramatic growth. These equipment include stepper, laser etching machine, thin-film depositional equipment, ion implanter, laser scribing machine, laser hole drilling machine and so on. 

As what can be seen above, most of the semiconductor material processing machine is supported by laser technique. Laser light beam can have a unique effect in processing semiconductor material due to its non-contact, highly efficient and precise quality. 

Many silicon-based wafer cutting job used to be done by mechanical cutting. But now, precision laser cutting takes the charge. Laser technique features high efficiency, smooth cutting edge and no need of further post-processing and without producing any pollutant. In the past, laser wafer cutting used nanosecond UV laser, since UV laser is characterized by small heat affecting zone and is known as cold processing. But in the recent years with the update of the equipment, ultra-fast laser, especially picosecond laser has been gradually used in wafer laser cutting. With the power of ultra-fast laser continues to increase, it is expected that picosecond UV laser and even femtosecond UV laser will be widely used to achieve more precise and faster processing. 

In the near future, the semiconductor industry in our country will enter the fastest growing period, bringing huge demand of semiconductor equipment and the huge amount of wafer processing. These all help promote the demand of laser micro-machining, especially ultra-fast laser. 

Semiconductor, touch screen, consumer electronics parts manufacturing will be the most important applications of ultra-fast laser. For the time being, domestic ultra-fast laser is experiencing a rapid growth and price is going down. For example, for 20W picosecond laser, its price reduces from the original 1 million RMB to less than 400,000 RMB. This is a positive trend for the semiconductor industry. 

The stability of the ultra-fast processing equipment is closely related to the thermal management. Last year, S&A Teyu launched the portable industrial chiller unit CWUP-20 which can be used to cool femtosecond laser, picosecond laser, nanosecond laser and other ultra-fast lasers.

The future and the main applications of CO2 laser

 CO2 laser was invented by C.Kumar N.Patel in 1964. Ii is also called CO2 glass tube and a laser source that has high continuous output power. CO2 laser is widely applied in textile, medical, material processing, industrial manufacturing and other areas. It plays a major role in package marking, non-metal materials cutting and medical cosmetology.

In 1980s, CO2 laser technique had already become mature and in the later 20+ years, it has been used in metal cutting, different kinds of materials cutting/engraving, automobile welding, laser cladding and so on. The current industrial-use CO2 laser has 10.64μm as wavelength and the output laser light is infrared light. The photoelectric conversion rate of CO2 laser can reach 15%-25%, which is more advantageous than solid state YAG laser. The wavelength of CO2 laser decides the fact that the laser light can be absorbed by steel, colored steel, precisou metal, and many different kinds of non-metals. Its range of applied materials are much broader than that of fiber laser. 

For the time being, the most important laser processing is no doubt laser metal processing. However, since fiber laser became quite heated in the domestic and oversea market, it has accounted for some of the market share that used to belong to CO2 laser cutting in metal processing. This might lead to some misunderstandings : CO2 laser is outdated and no longer useful. Well, in fact, this is totally wrong. 

As the most mature and most stable laser source, CO2 laser is also very mature in the process development. Even today, many applications of CO2 laser are still found in European countries and the United States. Many natural and synthetic materials can also absorb well the CO2 laser light, providing so many opportunities for CO2 laser in material treatment and spectral analysis. The property of the CO2 laser light decides the fact that it still has unique potential of application. Below are a few common applications of the CO2 laser. 

Metal material processing

Before fiber laser became popular, metal processing mainly used high power CO2 laser. But now, for cutting ultra-thick metal plates, most of the people would think about 10KW+ fiber laser. Although fiber laser cutting does replace some of the CO2 laser cutting in steel plate cutting, it doesn’t mean CO2 laser cutting will disappear. Till now, many domestic laser machine manufacturers like HANS YUEMING, BAISHENG, PENTA LASER can still provide CO2 metal laser cutting machines. 

Because of its small laser spot, fiber laser is easier for cutting. But this quality becomes a weakness when it comes to laser welding. In thick metal plate welding, high power CO2 laser is more advantageous than fiber laser. Although a few years ago, people began to overcome the weakness of fiber laser, it still can not outperform CO2 laser. 

Material surface treatment

CO2 laser can be used on surface treatment, which refers to laser cladding. Although nowadays laser cladding can adopt semiconductor laser, CO2 laser dominated the laser cladding application before the advent of high power semiconductor laser. Laser cladding is widely used in molding, hardware, mining machinery, aerospace, marine equipment and other industrial areas. Comparing with semiconductor laser, CO2 laser is more advantageous in price. 

Textile processing
In metal processing, CO2 laser is facing the challenges from fiber laser and semiconductor laser. Therefore, in the future, the major applications of CO2 laser would probably depend on non-metal materials like glass, ceramics, fabric, leather, wood, plastic, polymer and so on. 

Custom application in special areas
The light quality of CO2 laser provides big possibility of custom application in special areas, such as polymer, plastic and ceramics processing. CO2 laser can perform high speed cutting on ABS, PMMA, PP and other polymers. 

Medical application
In the 1990s, high energy pulsed medical equipment that uses ultra-pulse CO2 laser was invented and became quite popular. Laser cosmetology becomes especially popular and has a very bright future.

CO2 laser cooling

CO2 laser uses gas (CO2) as a medium. No matter whether it is RF metal cavity design or glass tube design, the inner component is very sensitive to the heat. Therefore, high precision cooling is very necessary to protect the CO2 laser machineand maintain its lifespan.

S&A Teyu has been dedicated to developing and manufacturing laser cooling equipment for 19 years. In domestic CO2 laser cooling market, S&A Teyu accounts for the bigger share and has the most experience in this area. 

CW-5200T was a newly developed energy efficient portable laser water chiller from S&A Teyu. It features ±0.3°C temperature stability and dual frequency compatible in 220V 50HZ and 220V 60HZ. It is very ideal for cooling small-medium power CO2 laser machine. Find out more about this chiller at https://www.teyuchiller.com/sealed-co2-laser-tube-water-chiller-220v-50-60hz_p234.html

The development and breakthrough of domestic laser water chiller

 Laser is considered as one of the most representative novel processing technique. It realizes cutting, welding, marking, engraving and cleaning by using laser light energy on the work pieces. As a “sharp knife”, more and more applications of laser are found. For the time being, laser technique has been used in metal processing, molding, consumer electronics, automobile parts, aerospace, food & medicine and other industries.

2000 to 2010 are the 10 years when domestic laser industry began to grow. And 2010 till now are the 10 years when laser technique is thriving and this trend is going to last. 

In laser technique and its new products, the major players are of course the laser source and the core optical element. But as we know, what really makes laser becomes practical is the laser processing machine. Laser processing machines like laser cutting machine, laser welding machine and laser marking machine are the integrated products that combines optical, mechanical and electronic components. These components include machine tool, processing head, scanner, software control, mobile system, motor system, light transmission, power source, cooling device, etc. And this article is focusing on the laser-use cooling device. 

Domestic laser cooling units are under rapid growth

Cooling device is generally divided into water cooling machine and oil cooling machine. Domestic laser applications mainly require water cooling machine. The dramatic grow of laser machine helps promote the demand of the laser cooling units. 

According to the statistics, there are more than 30 enterprises which supply laser water chillers. Just like the normal laser machines, the competition among laser water chiller suppliers are also quite fierce. Some enterprises originally deal in air purification or refrigeration transport but later enter into the laser refrigeration business. As we know, industrial refrigeration is an industry of “easy at the beginning, but hard on the later stage”. This industry will not be this competitive for a long time and a small number of enterprises with superior quality product and well-established after-sales service will stand out in the market and accounts for the most of the market share. 

Nowadays, there are already 2 or 3 enterprises standing out in this fierce competition. One of them is S&A Teyu. Originally, S&A Teyu mainly focused on CO2 laser chiller and YAG laser chiller, but later expanded its business scope to high power fiber laser chiller, semiconductor laser chiller, UV laser chiller and later ultra-fast laser chiller. It is one of the few chiller suppliers that cover all types of lasers. 

During the 19 years of development, S&A Teyu gradually becomes a well-recognized brand by the laser machine suppliers and the laser end-users with its reliable performance and high stability. Last year, the sales volume reached 80000 units, which is leading in the whole country. 

As we know, one of the most important parameters of laser chiller unit is cooling capacity. Chiller with higher capacity can be used for higher power application. For the time being, S&A Teyu has developed air cooled recirculating laser chiller for 20KW fiber laser. This chiller has a proper design in the chiller body and the closed water loop. Temperature stability is another important parameter. For high power laser machine, it generally requires temperature stability to be ±1℃ or ±2℃. By precisely controlling the temperature for the laser machine, a laser water chiller can ensure the normal working and the long lifespan of the laser machine. 

Besides, S&A Teyu continues to improve the cooling technology and launches new products, including chiller specifically designed for UV laser marking machine and UV laser cutting machine and chiller specifically designed for handheld laser welding machine of 1000-2000W with temperature stability of ±1°C. 

S&A Teyu has never stopped in the road of innovation. 6 years ago in an oversea laser fair, S&A Teyu spotted a high precision ultra-fast laser with temperature stability of ±0.1°C. The cooling technology of ±0.1°C temperature stability had always been controlled by European countries, the U.S. and Japan. Realizing the gap with these countries, S&A Teyu decided to innovate its cooling technology to catch up with its foreign counterparts. During these 6 years, S&A Teyu experienced twice failures, which indicates the difficulty to achieving this high temperature stability. But all the efforts got paid off. At the beginning of 2020, S&A Teyu finally successfully developed the CWUP-20 ultra-fast laser water chiller of ±0.1°C temperature stability. This recirculating water chiller is suitable for cooling solid-state ultra-fast laser up to 20W, including femtosecond laser, picosecond laser, nanosecond laser, etc. Find out more information about this chiller at https://www.teyuchiller.com/ultra-precise-small-water-chiller-cwup-20-for-20w-ultra-fast-solid-state-laser_p242.html

The development trend and forecast of fiber laser cutting

 Fiber laser helps promote the development of the laser industry

Fiber laser is the most revolutionary technical breakthrough of the laser industry in the past 10 years. It has become the main industrial laser type and accounts for more than 55% in the global market. With fantastic processing quality, fiber laser has been widely used in laser welding, laser cutting, laser marking and laser cleaning, promoting the development of the whole laser industry.

China is the most important fiber laser market in the world whose market sales volume takes up about 6% of the world. China is also leading in the number of the installed fiber lasers. For pulsed fiber laser, the installed number has already exceeded 200000 units. As for continuous fiber laser, the installed number is nearly 30000 units. Foreign fiber laser manufacturers like IPG, nLight and SPI, they all take China as the most important market. 

The analysis of the development trend of fiber laser

According to the data, since fiber laser became the mainstream of the cutting application, the power of the fiber laser has become higher and higher. 

Back in 2014, laser cutting application became mainstream. The 500W fiber laser soon became the heated product in the market at that time. And then, the fiber laser power increased to 1500W very soon. 

Before 2016, the global major laser manufacturers thought that 6KW fiber laser was sufficient to meet most of the cutting need. But later, Hans YUEMING launched 8KW fiber laser cutting machine, which marks the beginning of the competition on high power fiber laser machines. 

In 2017, 10KW+ fiber laser was created. This means China entered the 10KW+ fiber laser era. Later, 20KW+ and 30KW+ fiber lasers were also launched one by one by laser manufacturers both home and abroad. It was like a competition. 

It is true that higher fiber laser power means higher processing efficiency and laser manufacturers like Raycus, MAX, JPT, IPG, nLight and SPI are all making contribution to the development of the high power fiber laser. 

But we must realize an important fact. For materials more than 40 millimeter wide, they often appear in high-end equipment and some special areas in which 10KW+ fiber laser will be used. But for most of the products in our daily life and industrial manufacturing, the laser processing need is within 20 millimeter wide and this is what 2KW-6KW fiber laser is capable of cutting. One one hand, laser machine suppliers like Trumpf, Bystronic and Mazak focus on providing laser machine with suitable laser power instead of developing high power fiber laser machine. One the other hand, the market selection indicates that 10KW+ fiber laser machine doesn’t have as many sales volume as expected. On the contrary, the sames volume of 2KW-6KW fiber laser machine has witnessed the rapid growth. Therefore, users would soon realize that the stability and the durability of the fiber laser machine are the most important thing, instead of “the higher the laser power, the better”. 

Nowadays, fiber laser power has become a pyramid like structure. On the top of the pyramid, it’s 10KW+ fiber laser and the power is becoming higher and higher. For the biggest part of the pyramid, it’s 2KW-8KW fiber laser and it has the fastest development. At the bottom of the pyramid, its’ fiber laser below 2KW. 

What S&A Teyu did to meet the medium-high laser power market need?

With the pandemic being controlled, the laser manufacturing need returns to normal. And 2KW-6KW fiber lasers are still the most needed one, for they can meet most of the processing demands. 

To meet the market need of medium-high power fiber laser, S&A Teyu developed CWFL series water circulation chiller, capable of cooling 0.5KW-20KW fiber lasers. Take S&A Teyu CWFL-6000 air cooled laser chiller as an example. It is specifically designed for 6KW fiber laser with temperature stability of ±1°C. It supports Modbus-485 communication protocol and is designed with multiple alarms, which can provide well protection for the fiber laser machine.
