Rebirth of Northern Technology

Laser cutting machine is regarded as the second killer of optoelectronic research in the field of LED equipment. But there is a problem here. Laser cutting technology cannot be protected by patents.

Lasers, as well as laser cutting, are common in the machining industry. This time it is only used in the semiconductor industry.

Laser cutting can not apply for patents, and the next best thing is to apply for some peripheral patents in optoelectronic research. For example, the position of the laser focus, the cutting method, etc., create some trouble for others. This includes the more famous stealth cutting technology (StealthDicing) in later generations.

However, these patented technologies cannot completely prevent other players from entering this field, because the accuracy of the wafer has not yet advanced to the time when these high-precision technologies are needed.

But in the short term, this situation should not happen.

The main reason here is that the LED market is not big enough at this time. Equipment manufacturers, it is not worth investing such a large amount of energy to run into this market segment, and have already occupied the first-mover advantage of optoelectronic research.

Therefore, at least there is still a period of time for optoelectronic research to enjoy this market exclusively. As for how long this exclusive enjoyment is, let's count as one day after a day.

"Why are there two cutting machines here? Is there any difference between them?"

Someone found a new problem. The two machines in the room are very different in structure.

"Although the two machines both use laser technology for cutting, they have different principles."

Cheng Yongxing walked out from behind the crowd and took over the right to understand.

"What we saw before our eyes, the one on the left has actually met the accuracy requirements for current production. This is also the preferred target recommended for everyone at this stage. The one on the right is prepared for future production. Contains a new patented laser cutting technology, "LaserMicroJet"."

"It's a patented technology again? What are its advantages?"

"The advantage of the laser micro water jet is that the laser is focused and directed into a micro water column that is thinner than the hair, so as to guide the beam and cool the workpiece, eliminating the defect of the traditional laser heat affected zone (HeatAffectedZone) too large. Thus improving the laser The cutting quality is therefore very suitable for high-end LED processing occasions."

"What do you mean by high-end?"

"Maybe it's a laser in the future, who knows?"

Cheng Yongxing actually doesn't know much about this new patented technology. Just looking at the appearance of admiring this technology in later generations, I cut it off handily. As for when this thing is useful and what is it, it is still unclear.

The LED field is not available for the time being, and perhaps in other fields, such as aerospace, it can find a market.

A group of people lost interest in this more high-end machine after seeing it for a while. Useless technology is useless no matter how advanced it is.

"We hope to order two laser cutting machines!"

Joseph of Philip raised his hand.

The MOVCD order has already been placed, and Philip owns the lithography machine, so it is impossible to outsource it. The laser cutter became his first target. Philip's equipment order cannot be delayed any longer.

"We have to order two too!"

President Yan Tian also made a voice in the crowd.

"If you place an order now, when will you be able to deliver it?"

Driven by the two companies, a group of people were moved. Different voices sounded one after another. This kind of special equipment is produced by hand in small batches.

"This is probably the first large-scale export of semiconductor equipment in our country!"

Mayor Luo and Minister Gu stood side by side on the periphery of the crowd. Looking at the scene in front of me, I couldn't help but feel it.

"Probably not. In the 1970s, the ion implanter of the Shanghai Metallurgical Institute was exported to Japan."

Minister Gu had to explain.

The lively scene in front of him gave him an unreal feeling.

Although LED equipment is more special, compared to integrated circuits, the difficulty is not a little bit lower. But no matter how difficult it is, this is also a semiconductor device.

In the late 1970s and early 1980s, China's semiconductor equipment industry had a glorious period of time. But this brilliance is only a flash in the pan.

This result is also related to the state's investment.

With the decline of the national economic situation in recent years, the funds in the hands of the central government have become increasingly tense. As a result, in the field of integrated circuits, China has drifted farther and farther on the road to catch up with its counterparts in the world.

The separation of national taxes and local taxes implemented in 1994 was essentially aimed at regaining financial resources from local governments.

In the past few years, many plans have been formulated by the Ministry, but they have not been implemented. Including the famous 908 plan.

The country has no money.
