Rebirth of Northern Technology

New building, fifth floor,

The doors of all classrooms are open.

Due to the conference, classrooms on the third, fourth, fifth, and third floors were completely expropriated and used as temporary exhibition spaces.

At the end of the corridor, a group of white men walked out of the elevator room surrounded by a Chinese youth.

"Optical research not only focuses on the research and development of LED technology, but also invests huge manpower and material resources to develop LED production technology and equipment. In these rooms, we introduce the overall solution of our company's production line. !"

Cheng Yongxing's face was not red and heartbeat. He pretended to be an expert in large-scale industrial production in front of foreigners, and introduced the advanced production experience that did not exist.

Optoelectronics research is facing the construction of a new production line. In fact, all LED manufacturers are facing similar situations more or less. In particular, the base material and production process of blue LEDs are different from traditional red and green LEDs. Each company is also facing the difficult problem of process design and process equipment selection.

This is also the reason why this group of people put aside other technical discussions and did not listen, and came to join him.

————————

"In the first room, there are two MOVCD devices. The first is the type II device that everyone is already familiar with. Most of your orders are for this model, so I won't say much.

The main thing we need to introduce today is the second one, which is our replacement product, the Type III GaNMOCVD equipment. Everyone can see the difference between it and the previous generation product from the appearance. "

Type III equipment, due to its large size, almost never came in. Its size is three times that of Type II equipment.

"What are the characteristics of this device?"

The audience looked at the apparently enlarged volume and began to worry about their wallets.

The price of MOCVD for optoelectronic research is not cheap at all. Everyone buys with their eyes closed because they have no choice. But the first batch of products have not yet been obtained, and their products have actually been upgraded?

"The main goal of this product upgrade is to improve production efficiency and product quality. In order to overcome some of the limitations of the double blowing method in large-scale industrial production, we have spent a lot of money to develop a new generation of radial cross flow systems. .

This new process method makes it possible to process multiple epitaxial wafers at the same time. The staff will give you a demonstration below. "

Following the voice, the demonstrators of the Science Instrument Factory who had been preparing for a long time began to perform to everyone.

In fact, the machine in front of us has not completed the final product design work. Because the technicians have not fully understood the design sketches and ideas sent by Cheng Yongxing. But now it’s no problem to pull it out for a show.

"What is the yield of this equipment? How long will it take to produce it? What is its price?"

"Can our previous order be replaced with this model?"

Seeing the staff, three pieces of sapphire substrates can be put into the operating tray at one time, and the visitors immediately become excited. time is money. The efficiency of this machine is at least equal to three of the previous models!

"This type of equipment is still undergoing final finalization and acceptance, and will not be put on the market in the short term. It is estimated that its earliest delivery time will be next year."

Cheng Yongxing's voice attracted everyone's attention from the machine.

"Why introduce to us the product that will be delivered next year?"

Someone is finally upset.

But the question was not answered and clarified.

The purpose of letting you see the next generation of products is to dispel your self-confidence!

The research and development of blue LED related equipment, you will die of your heart!

————————

Soon, the crowd followed in the footsteps of the young people and rolled to the second room.

"This room shows two dedicated LED lithography machines! Their accuracy is 10 microns."

Two lithography machines manufactured by different manufacturers are placed in the room. The core machine is purchased out, but simple fixtures have been added to help production workers to operate.

"10 microns, this accuracy is nothing special. Does it have any other characteristics?"

A group of spectators whose appetites have been naughty expressed their first contempt for the simple machine they saw in front of them.

"If there is a feature, there is also one, and that is cheap!"

From the hands of several staff members guarding the machine, Cheng Yongxing took over two dozen leaflets and handed them out to everyone behind him.

"Cheap? Oh, it's true! It's really cheap."

Domestic products are not good quality, but they are definitely cheap.

The precision of the lithography machines used by each company is not low. But this is not because LED production requires such high precision, but there is no cheaper model anymore.

These low-cost domestic lithography machines are not competitive at all for wafer production, but they are suitable for LED production.

————————

"The two devices placed in this room are the third core machine in the blue LED production process, the cutting machine!"

Soon, the boss visiting group walked into the third room. Like the previous two rooms, there are two machines side by side here.

"Hey, why didn't you see the diamond grinding wheel?"

Everyone gathered around these two machines and started to see them. But soon, some guests who know the technology discovered the peculiarities of these two devices.

"This is our latest research result. Their characteristic is to use laser for cutting!"

Li Xiao took over the responsibility of explaining to the guests. Sister Li also dressed up today. People are different with and without makeup. Today, it looks like a beautiful woman.

"Laser? Are you using lasers for cutting?"

The hardness of sapphire is very high. The traditional cutting method has problems such as high loss rate and complicated follow-up procedures.

The non-contact cutting with laser is beyond everyone's expectations, but when you think about it, you will find that it makes sense again.

————————

Judging from the situation seen in the past two days, whether it is from the LED technology itself, LED applications, LED market research, and even process equipment, optoelectronic research has been far ahead of the world. Optoelectronic research and everyone's thinking are not even on the same level.

The design ideas of the several devices visited today are obviously more mature and more efficient.

In particular, the laser cutting solution in front of us has conceptually crushed all diamond cutting solutions on the market.

The traditional diamond scribing machine is rotated by a motor, which drives the expensive diamond grinding wheel to rotate, leaving scratches on the surface of the wafer.

This method requires very strict requirements on the accuracy of the diamond wheel's cutting edge. Due to the hardness of sapphire, second only to diamond in nature, the tool is very easy to wear. This kind of wear is not only extremely costly, but also causes constant fluctuations in product quality.

Tools that constantly need to be replaced will also attract additional calibration steps to prevent errors caused by manual operations. In addition, in terms of processing speed, laser cutting is also several times faster than knife cutting!

Finally, this contact cutting method puts high requirements on the machining accuracy of the motor, shaft, and other mechanical parts of the equipment.

This high-precision dicing machine integrates the highest machining level in the world, and its cost can be imagined.

Therefore, whether it is equipment cost, consumable consumption, product quality, or even the speed of wafer cutting, the diamond cutting solution has failed in an all-round way.

No matter how sophisticated your machine is, it's all rubbish!

The gap between the two sides has become so large that manpower cannot make up.
