Chapter 158 The Eve of Mass Production

On the first floor of Songhuajiang Semiconductor, there are tinkling sounds everywhere.

"This way, left, left, and a little bit up."

Wang Yanjun shouted and made gestures, commanding everyone to move the brand new lithography machine into place.

Behind him, there are busy figures everywhere.In addition to the staff of Songhuajiang Semiconductor itself, there are also installers from equipment manufacturers, construction personnel from construction companies, and most of them are decoration personnel from decoration companies.

Everyone is working hard for the same goal.

Bingfei is located in the frigid zone, and the construction period of the factory building is very long. In order to catch up with the precision, the company decided to transform the first floor of the office building into an LED production workshop.

Wang Yanjun, the former director of the MEMS Research Institute, rushed to the shelves and served as the first director of the LED workshop.

Wang Yanjun put down the research work of MEMS sensors, and dealt with ordering, receiving goods, and equipment installation.

The reason why the construction schedule was pressed very fast was because the company expected that the new blockbuster product, blue-ray LED, could be launched at the same time as Chen Quan's thesis.With the enthusiasm brought by new papers, we can create momentum for product promotion and create the greatest benefits.

There is no opposition within the company to this arrangement.There are many voices of opposition, even Wang Yanjun, the person involved, thinks it is reasonable.

After all, the brightness problem of blue LEDs has not been completely resolved. Under such circumstances, the company hastily entered a new market, and many people have no idea.

Many people are afraid that this new blue LED will be a fake star product just like the MEMS sensor.

Although MEMS sensors have been listed as a key support target by the state, judging from the information collected so far, Songhuajiang Semiconductor wants to make profits from it, and it is not something that can be done within three to five years.

However, under the influence of Chen Quan's aura of genius and the strong support of the leadership, relevant decisions were made and quickly implemented.

Of course, the reason why the decision is so easy is also related to the relatively low investment in the production line of blue LEDs.

In the LED process, the required lithography machines, etc., belong to traditional semiconductor equipment, and are widely used in the MEMS process. After the MEMS equipment orders are placed, the enthusiasm of domestic manufacturers is even higher than that of Songhuajiang Semiconductor.Maybe it was in stock, maybe it was a minor change, and the manufacturers quickly sent most of the equipment over.

These devices are also idle, and after a little adjustment, they can be used for LED production.

Of course, LEDs also have a large number of processes that are not compatible with MEMS, such as the processes after LED squares: cleaning, mounting, bonding, packaging, welding, film cutting, assembly, testing, packaging, etc.But this part of the work is mostly manual operation, and the investment in equipment is not too large, and a small assembly line can handle it all.

The only obstacle to the construction of LED workshops is the acquisition of upstream raw materials, such as sapphire and various chemical gases.

On the second floor, the MEMS Research Institute.

Qu Yanqiu and a group of researchers from the Laser Institute of the Industrial University of Technology had a heated discussion around a high-precision scribing machine.

Chen Quan gradually faded out of daily technical and administrative work on the grounds of being busy with his studies. Most of his work was shared by Feng Yan and Qu Yanqiu.

"How did you come up with the idea of ​​using lasers for cutting?" Li Xiao from the Laser Institute asked.

"Look!" Qu Yanqiu pointed at the pile of discarded diamond grinding wheels behind her. "With a diamond scribing machine, the cost is too high, and the consumption is too large."

In all IC production processes, an important step is to separate the finished IC from the wafer.

The principle of the dicing machine is that the motor drives the expensive diamond grinding wheel to rotate, leaving scratches on the surface of the wafer.Because the texture of the wafer is very brittle, the wafer will crack along the scratches with just a light tap.

This method has very strict requirements on the edge precision of the diamond grinding wheel, so the cost of consumables is extremely high.

Among blue LEDs, the base material used is not silicon wafer but sapphire.Due to the hardness of sapphire, which is second only to diamond in nature, the wear speed of diamond grinding wheel is extremely fast.

This kind of wear and tear is not only extremely costly, but also causes constant fluctuations in product quality.Because every time the grinding wheel is changed, manual correction is required.

"Your thinking is right." Li Xiao gave an affirmative answer after a brief discussion with the group of people behind her. "For sapphire with a hardness of up to 8, the laser is actually the only way out."

"This device, what can it provide us at the earliest?"

"According to the sketches you provided, all the corrections will be done manually, and no automation will be pursued. Within three months, we will be able to provide a prototype."

It is indeed the first time in the world that lasers are used in IC processing, but it is very common in the field of metal processing.So Li Xiao's team has a lot of confidence.

"Then we can rest assured."

Qu Yanqiu felt relieved.Chen Quan is not here, she has to worry about everything.

Laser cutting machine is an important link to further improve production efficiency and reduce production costs.

Using a diamond dicing machine, in addition to the high cost, there is also the problem of physical scratches.In order to ensure product quality, when designing process parameters, a considerable safety distance must be left on both sides of the scratch.

After laser cutting, more LED chips can be cut out on the same area of ​​sapphire substrate at a lower cost.

Li Xiao is also very happy that the project has taken shape. "By the way, why haven't you seen Chen Quan recently?"

"He, he went home to tutor his younger sister. His younger sister, Chen Ying, is about to take the high school entrance examination." Qu Yanqiu explained.

"Really?" Li Xiao didn't quite believe it.

Because on campus, a new rumor was circulating.That is, Qu Yanqiu completely hid Chen Quan who was in the limelight.

It has been several weeks, but no beautiful girl can come to Chen Quan's side.Now even Li Xiao, an old lady, is no exception.
