For three whole days, the whole Flint Research Institute was on holiday, in the name of preparing to meet the acceptance of the results of the special scientific research plan for precision instruments and machinery.

In fact, after Zhao Hongtao arranged for someone to take care of Gu Song's large laboratory, Gu Song was the only one in it.

Zhao Hongtao didn't know what Gu Song was doing inside, so he didn't ask, he just sent Gu Song food over on time.

This chip is purely time-consuming.

I had to do everything by myself to operate the instrument, and it took a whole day just to make the mask template.

Gu Song rested for a night to recuperate, and got up the next morning to officially start work.

The parameters of each step of the exposure are calculated. Just setting these parameters took Gu Song half a day.

Before the official start of construction, it took nearly two hours to evenly bake an 8-inch wafer that met the requirements.

It took nearly half an hour to put the mask and wafer in place, and it took nearly half an hour to confirm that all the parameters were fine, and then Gu Song began to press the start button and wait for the exposure to be completed.

The exposure time is very fast, so I don't know how it will work.

After the development, Gu Song first checked.

After turning on the "Focus Computing" mode, it took nearly 1 hour to make a preliminary confirmation, and I felt that there should be no problem.

Hard baking, etching, and finally removing the photoresist to get this palm-sized chip.

Although it is the size of a palm, its process is not low.

There is no way, there is no advanced process equipment to make the next generation of stereoscopic network chips based on nano-carbon materials. Under the current silicon-based semiconductor process idea, it can only be made with a simplified version to achieve basic functions.

He hurriedly took the chip over and tested it to see if there was any problem.

Now this is a bare die test, and the Probe card used for the test has to be re-set up to see if there is a problem with this chip first.

As soon as the test results came out, Gu Song felt congested.

On a wafer, four chips made at one time have all problems.

The die test has not passed, so there is no need for packaging.

He sat down in his chair and sighed, looking at the sky outside that was already dark, the day had been wasted.

The parameter setting is fine, and I don't know if the alignment accuracy is not enough, or there is a problem with the development.

He asked Zhao Hongtao to bring the rice over, while continuing to mix the glue and bake it before, ready to continue.

That's a good deal!

……

Zhao Hongtao stayed until almost lunch on the second day, when he saw Gu Song come out of it.

When he saw the boss's appearance, he was startled: "I haven't slept all night? I saw that you didn't ask me to bring breakfast, thinking you hadn't gotten up yet." ”

Gu Song looked tired, and his eyes were very sour.

It was only after the third pass that it was confirmed that the parameters needed to be adjusted slightly due to the error of mechanical accuracy.

Fortunately, with the data of three times, "Xie Xiaobao" quickly provided more accurate parameters.

The fourth time was in place, and the first success, although two of the four chips were also scrapped.

After encapsulating the two good chips and testing them again to make sure that there was no problem, Gu Song reset the parameters in the machine, deleted the records, and destroyed the mask before coming out of it.

"Go back to the Xiangshan Annex. Gu Song explained, got into the car and leaned on the back of the seat and began to sleep.

The car drove on the road for nearly an hour, and Zhao Hongtao woke him up: "I want to eat something." ”

Gu Song waved his hand: "You don't care about me, I'll eat a few slices of bread to deal with it first, I'm sleepy." ”

Too lazy to care about the equipment in the basement, Gu Song nibbled on bread and put the finished chip in the laboratory, and then went back to the bedroom and fell asleep.

This night, I slept until more than seven o'clock in the evening.

"Brother Zhao, you haven't left yet?" he came out of the bedroom and saw Zhao Hongtao sitting in the living room reading a book.

"I'm afraid what's wrong with you? Hungry, aren't you? I'm going to stir-fry. Zhao Hongtao got up and walked to the kitchen.

After more than three years, Zhao Hongtao, who loves learning, has even mastered cooking skills very well.

This side of the Xiangshan Villa didn't come often before, and it was relatively confidential, and no one was here to help.

Recently, there have been more people here, and Zhao Hongtao drove to a nearby town to buy vegetables and come over to cook.

Gu Song was also used to it, and said to him: "Call me later, I'll go to the basement." ”

I went into the basement and had time to see how it was going.

Three days passed, and the structural components were all done.

Gu Song is not afraid of waste, and every structural component is processed from a complete piece of material. Fortunately, the precision instruments are okay, except for the brainwave sensor, the other non-critical ones are all substitutes that can be used now.

It's a little bit worse, machine 0.

The spare parts of the brainwave sensor are also processed and lie there.

Again, you need to do some testing before putting it together.

Fortunately, the test of this thing is quite simple, as long as it is confirmed that the signal can be detected and the sensitivity is enough.

As soon as Gu Song was satisfied, Zhao Hongtao called and said that the food was ready. Gu Song placed all the parts, including the chips, on the workbench that had been prepared long ago and pushed them next to the robotic arm.

The assembly procedure was initiated, and the robotic arm, which was still artificially retarded, began to execute the assembly procedure step by step.

Gu Song looked at this scene with a smile and nodded, humming a pleasant tune and went upstairs.

Zhao Hongtao asked with a smile: "Have you done anything busy these days?"

Gu Song made an OK: "It's done!

"If you don't go anywhere else at night, then it's on the hour. Then he went and got the wine and the glass.

The two sat down, and one poured a small glass. Gu Song took a sip and said happily: "The hard work is not in vain, your boss and I are about to upgrade!"

Zhao Hongtao didn't know what he meant by the upgrade, and the warning he gave himself now anyway was very clear: just listen, don't ask nonsense.

He took a sip with him, and Gu Song said, "How is your team expanding? This time, we went to the United States to suffer a loss, and we can't eat it again in the future. ”

"Still recruiting. ”

Gu Song nodded: "I won't go anywhere else before the Lihu Conference, you take the time to learn how to fly an airplane, anyway, it is to learn the Gulfstream G550 accurately." Although we can buy the general aviation company in the future, it is not our own team now. ”

Zhao Hongtao was a little in a trance, but he didn't expect to start learning this thing.

Gu Song looked at his appearance and said with a smile: "You have to get used to it, now it's just in case, we have to have a team of pilots ourselves." And don't forget, I'm going to build a spaceship in the future, can I trust someone else when the time comes?"

Zhao Hongtao was not only in a trance now, he couldn't help but ask more; "Open...... Spaceship?"

Gu Song took another sip of wine: "Learn the airplane first, and then learn the spaceship later, you have to be mentally prepared." ”

Zhao Hongtao looked at him speechlessly, this kind of psychological preparation ...... Not really!
