Chapter 1453 Our lithography machine dilemma (110)

The lithography machine, everyone was at a loss.Lithography machine is also known as grinding alignment exposure machine, exposure system, lithography system, etc.The commonly used lithography machine is mask alignment lithography, which is also the most widely used manufacturing technology in the field of chip manufacturing.Lithography is actually translated from English Photolithography, which means to use light to make a graphic.Spread the glue on the surface of the silicon wafer, and then transfer the pattern on the mask plate to the photoresist to temporarily "copy" the device or circuit structure to the silicon wafer.The general photolithography process has to go through the processes of cleaning and drying the surface of the silicon wafer, primer coating, spin-coating photoresist, soft baking, alignment exposure, post-baking, developing, hard baking, and etching.

After this explanation, everyone understands that it is a machine for producing and processing chips.As for the English name, engraving, and exposure, most people are at a loss.

Seeing everyone's dejected affection, Lin Xiaonan smiled slightly and continued, "However, just when we were a little desperate, this matter has turned around, and we also have our own lithography machine."

"Oh, really?" Everyone said in surprise.

Lin Xiaonan glanced at Jiang Chen, then nodded and said, "This is all thanks to Mr. Jiang's relationship. Through secret channels and the help of some friendly compatriots, we have obtained special channels from Japan and Treasure Island. The price brought back two lithography machines. Although these two lithography machines are several years ago, that is, the technology in the middle and late 80s, the resolution is only 436 nanometers, which is far lower than the current international leading 300 nanometers. But it is also a zero breakthrough for us. And these people also underestimated our strength, I believe we will not take long to understand their technology, and thus catch up with them and surpass them."

"Good!" Everyone cheered and applauded.Only Jiang Chen's expression was a little dignified.Because he knows that it is not easy to catch up with others.Even after so much investment in later generations, the development is still slow, and our country's chips are still heavily dependent on others.And even the chips we developed and designed are manufactured by other companies, and we don't even have a manufacturing plant in this area.I remember that in later generations, people have been able to manufacture chips with a 14-nanometer or even a 10-nanometer process.But now they are still lingering on 436, and the manufacturing equipment is still smuggled in from overseas through special channels at a high price.

These two obsolete machines cost 7000 million U.S. dollars, of which the one in Japan cost 3000 million U.S. dollars, and the one in Baodao cost 4000 million U.S. dollars.It can be said that it was severely slaughtered by others, but in fact this kind of equipment is worth several million dollars to others, or even lower than this.There is no way, although we know that they are slaughtering them, but we have to bite the bullet and let them slaughter them. Who made us blank in this regard.

"Then specifically, in the chip manufacturing process, we have reached that stage?" Jiang Chen asked Lin Xiaonan.

After hearing Jiang Chen's words, everyone fell silent, and then looked at Lin Xiaonan.Regarding this, Lin Xiaonan said to Jiang Chen and the others: "President Jiang, this way please."

While talking, Lin Xiaonan led Jiang Chen and the others to the edge of the glass wall, then picked up the red phone next to it and said to the inside, "Xiao Xu, show President Jiang and everyone the chip we have developed."

A young man wrapped in a white protective suit in the clean area nodded to Jiang Chen and the others, then took a piece of tweezers from a device and picked up a thin slice about the size of a mung bean and showed it to everyone.

"Is this a chip?" The fat man asked in surprise.

"That's right, this is the first chip we manufactured using one of the lithography machines according to our design drawings, and we named it Taiyi No. [-]." Lin Xiaonan nodded and smiled.

Taiyi, Jiang Chen nodded in appreciation and said, "It's probably from the sentence 'Taiyi, I don't see Qi' in "Liezi"."

"Hahahaha, Xiao Jiang is really knowledgeable. I thought of it so quickly." Mr. Zhu laughed and said, "It is taken from "Liezi". A cosmic state of infinite nothingness."

Jiang Chen nodded and said with a smile, "You're flattering yourself. But the name is good, and our domestic chips are in such a state. It's too easy, a good name."

"Hehe, we also hope to take this name to place our expectations on the development of our domestic chip industry. It is too difficult to start from scratch. The next step is to see the efforts of the younger generation."

"No, this chip is too small, it's very different from what I imagined." Fatty said at this time.

"Then what kind of chip do you want?" Jiang Chen couldn't tell whether to laugh or cry when he heard the fat man's words.

"I was thinking, even if such a powerful thing is not as big as a watermelon, it is at least about the size of an apple. Why is it so small, only the size of a mung bean, is this thing good?" The fat man looked at the chip on the tweezers Then they turned to Jiang Chen and they didn't believe it.

"Hahahaha,,," Everyone burst into laughter when they heard the words, only Jiang Chen couldn't laugh or cry, he wanted to kick this guy out now, is there such a metaphor?

And Dongzi next to him may have been influenced by Lin Xiaonan, so he can understand some of these things, so he dragged the fat man over and explained: "This thing is not the bigger the better, but the smaller the better,, ,"

After Dongzi's explanation, the fat man finally knew what was going on.Seeing everyone's smiles, his old face couldn't help turning red and said: "Hey, I'm not a technical person, so I know so much, you all stop laughing."

"Hahahaha,,," the crowd laughed again.Jiang Chen turned to look at Lin Xiaonan and said, "So, our first chip has been manufactured successfully?"

Lin Xiaonan nodded, but shook his head again and said: "This is just a trial production using other people's machines, and we need to continue to test and modify it later. If you want to put it into large-scale commercial production, it is basically impossible It is possible, unless we can master all the technical principles of the entire manufacturing process and thoroughly understand all the technologies of these two lithography machines. In this way, we can create our own lithography machine, so that we can put it into large-scale production. And the one we developed There is still a certain gap between this chip and the current similar chips in the world, and if we want to catch up with this gap, I am afraid we need to continue to work hard.”
