Big Country Intelligent Manufacturing

"Take me to see your first qualified product?" Putting aside the issue of the UV light source, Xu Zhenming changed the subject and was going to see the first Dolphin I-1 chip.

This high-precision chip made with four-layer and a half-lithography process technology has a memorial value much higher than the actual economic value.Therefore, Zhang Neojing and others have sealed this chip with plexiglass and displayed it in the product exhibition room of Mingxin Manufacturing Company.

Hearing that the boss is going to take a look at their achievements, Zhang Neojing is naturally very happy, "Haha...Xu Dong, you are finally willing to care about the achievements of our subordinates."

"Who said no. Xu Dong hasn't come to our factory for a long time."

"Hey, wait a minute. Xu Dong, let's go to Factory No. 3 first. There is a good product over there." At this moment, Hu Mingzhen waved his hand grinningly.He pulled Xu Zhenming and wanted Xu Zhenming to inspect the first domestic etching machine.

Hearing these words, Xu Zhenming stopped and nodded solemnly, "Old bullshit is right, we should first go and see the domestic etching machine."

The localization of etching machines is a must for Chinese people. Yiming Group can complete this initiative in July 1997. Xu Zhenming thinks it is worth celebrating.

Not long after, everyone came to the No. 3 plant.

"Beep...beep...beep..."

"Be lighter, Xiao Zhang. You ask the operator to lift the plasma generator and place it in the air. You must do a good job of protection."

In the dust-free workshop, Guo Liansheng of Yiming Group Semiconductor Equipment Manufacturing Company is now loudly directing engineers to hoist equipment.In front of Guo Liansheng, the imported etching machine has been disassembled, and the forklift operator is lifting the plasma generator of the etching machine.

Seeing this scene, Xu Zhenming was a little stunned, "Old Hu, what are you doing?" He didn't understand, and didn't know what Guo Liansheng and others were doing.A good imported etching machine, why should it be disassembled at this time?

"Xu Dong, our domestic etching machine is actually reverse engineered to imitate the islander. Although we have done many tests in the laboratory, we are still not at ease, and we are ready to exchange the main components of the domestic etching machine with imported goods. "

Hu Mingzhen told Xu Zhenming that their team's plan was divided into three steps.

The first step is to use the host system imported from others. After all, they have high mechanical precision; the second step is to use their plasma system to compare the gap between domestic plasma technology and island plasma technology; the third step is to completely replace imported products. Change the domestic etching machine to the production line for inspection.

In this case, Guo Liansheng’s team is more careful and does not want to affect the normal production of the No. 3 chip production line.

"Is the accuracy required for the etching machine so high?" Xu Zhenming was a little surprised after hearing Hu Mingzhen's introduction.

There are two ways to circuit the circuit, one is wet etching and the other is dry.

Wet etching is the use of chemical reagents to etch the circuit board, thereby leaving the exposed circuit diagram.This method is generally used in products such as chips and electronic circuits with low precision.

But the Dolphin I-1 chip has a process accuracy of 130 nanometers, and currently only dry etching can be used to complete the circuit etching.

However, our country's technology in plasma beam light source generators is still behind foreign countries. The plasma beam generated by the light source has a relatively large divergence. The etched circuit is a bit rough and it is very likely to leak!

Hu Mingzhen frowned and introduced the situation of the etching machine to Xu Zhenming.In a word, this equipment is not simple!
