NOVEL SIMPLE Chapter 127
Chapter 127 Lithography
These days before the holiday, unlike the leisure of students, teachers are the busiest.
Zhao Weiwei ran twice, but did not find the right person to take them to familiarize themselves with the equipment.
Wang Qinian has also been busy recently. At the end of the year, various summaries and evaluations continue. In the end, he suggested that Zhao Weiwei would lead the younger brother and go around for a tour on his own.
The teachers are not free, but the machines are free.
Zhao Weiwei is also a top student in the Department of Electronics. Although microelectronics is not her research field, she still has some impressions about the specific functions of these devices.
So Cheng Yongxing, under the leadership of Senior Sister Zhao, came to the laboratory for a day trip. Simply establish some impressions.
This visit actually didn’t have the opportunity to operate, it can only be regarded as a spectacle, but it has greatly helped his next plan.
A lot of things on paper have been compared with the real thing. Some ideas have also changed.
—————————
As soon as he entered the laboratory, Cheng Yongxing felt that his time was wasted.
Hundreds of hours of online video have been watched in vain!
The laboratory in front of me, except for its appearance similar to that in the video, is quite tall.
What else…
If you have to go inside, it is very close to the garage laboratory of some enthusiasts. They are all collections of equipment from different ages, a few new equipment, plus a bunch of junk from second-hand scouring.
These devices come in various shapes and sizes. Some of them still feel like high-tech electronic devices, at least they have a control panel or something. And some, except for a switch, there is nothing, the appearance is not as good as the oven in the kitchen!
“This is an oxidation furnace. Hello! What are you looking for?”
Zhao Weiwei introduced the name of the equipment to the younger brother as she walked, but she disappeared in a blink of an eye.
“I’m looking for a lithography machine!”
When Cheng Yongxing entered the laboratory, he felt that the room was too small to hold down the lithography machine that everyone had hoped for.
“Isn’t that the lithography machine?” Zhao Weiwei pointed towards the corner.
Due to the upcoming holiday, there are only two of them in the laboratory.
“This is a lithography machine? So small?”
The photoetching machine in front of me is probably a circle larger than the ATM automatic teller machine on the street. It is about the same width as the normal workbench.
“It’s so small, can it be worth a hundred million dollars?”
Watch the video, ASML’s lithography machine is about the size of a bus.
“How many?”
Zhao Weiwei plucked her ears. I thought I heard it wrong.
“This is a domestically produced product made in Fengtian, suitable for laboratory use, and it costs about 100,000 yuan.”
“So cheap?”
—————————
“Why is it cheaper? It’s almost the most expensive equipment in the laboratory!”
“Almost? Is there anything more expensive than it?”
Cheng Yongxing came interested. In later generations, the word lithography machine will continue to be heard. In this era, I discovered that it is not the most expensive!
“The most expensive one is not in the laboratory. Outside, the laser printer is the most expensive.”
“Printers are more expensive than lithography machines?”
This is new!
In the future, who will have relatives and friends traveling, or time travel, tell them that they don’t need to bring anything else, just bring a printer on their back!
“Yes! I bought it with foreign exchange. This is not an ordinary printer, it can print on transparencies!”
“But that’s still a printer!”
Cheng Yongxing can’t understand the values here at all. Shook his head and walked to the black lithography machine.
No wonder things are cheap, but from the outside, they are a bit inconspicuous! And the vertical laser printer at the door is almost like the image of later generations.
How do you describe this so-called lithography machine? It is like a drilling machine with a shell buckled on the outside.
But no matter how simple, the price difference is too much! 100,000 to 100 million U.S. dollars? Such a large profit margin?
How about revising the plan and building the lithography machine first?
However, no matter what you do, one lesson to be learned is that product appearance is important. If things are good or not, let’s say it separately, look good!
The equipment in the house, I looked around at a glance, and they were basically old antiques.
Old antiques also have the advantage of old antiques, that is, simple operation. The technology is backward, but the price is also low.
I don’t dare to use a 100 million-dollar device!
These old antiques, do you still want to run?
—————————
“What is installed here?”
In a cover by the window, there are a series of transparent square bottles.
“Don’t mess around, these are acid-base solvents, dangerous!” Zhao Weiwei pulled a handful of students who were going to study carefully. She was not impressed by these things either, but just remembered the danger.
Taking a look at the label on the bottle, Cheng Yongxing was frightened this time.
In this laboratory, large and small, pots and pans, there are a lot of various acid and alkali solutions.
Toxic, non-toxic, corrosive, non-corrosive, non-volatile, volatile.
This is simply a chemical laboratory!
No wonder, you have to wear a mask and gloves before you come in.
This is not only for dust removal, but also for life.
After more than half a year’s experience, Cheng Yongxing’s ability to operate the equipment has increased. Even without reading the manual, the new equipment dares to illuminate. But for these acid-base solutions, it’s better to be careful!
Cheng Yongxing took the notes and copied the tags for a while, remembering to feel dizzy. Let’s talk about it then. These preparations, Zhao Weiwei is not very clear about their usefulness, and have to ask someone to inquire.
—————————
After reading the hardware, look at the software.
software?
do not have!
“Is Comsol software available?”
“Kang what?”
“What about Intellisuite?”
“What’s that? Xiaocheng, I know your English is good, but your Chinese is also good! Can we speak some human words?”
Zhao Weiwei’s English is good, and now she begs for mercy. She has never heard of these words.
“Ok…”
The teaching videos that Cheng Yongxing has watched are all in English. What is the name in Chinese?
However, if Senior Sister Zhao had no impression of this kind of thing, I believe it would not have appeared. There are some proper nouns that Chinese people are too lazy to translate. For example, Protel and Word are all English words directly.
How should Word’s Chinese be translated? “word”? This is definitely not right!
What about direct transliteration? “mine”?
It’s not plausible.
Cheng Yongxing actually walked for a while.
…
“Do we have any MEMS design software!”
“MEMS and design software?” Zhao Weiwei understood this time. “I really don’t know, please turn around and ask Teacher Wang. I have graduated for a few years, anyway, when I was studying, there was nothing.”
MEMS design requires special design software, such as (Intellisuite, Comsol). In these software, various three-dimensional structure, mechanical strength and other simulations and calculations are integrated. But for now, don’t even think about it.
“If there is no MEMS software, then Cadence, Synopsys, MentorGraphics, these software, what is there?”
Find a commonly used IC design software, it’s okay!
“What’s the matter? Do you speak English?”
Zhao Weiwei felt that her junior behaved a little abnormally since entering the laboratory. Mouthful of strange words.
“These are the three major hegemons in the EDA software industry. You don’t know this. Are you still a student of electronics?”
“What’s A?”
“Forget it, there is no common language with you, ancient people!”
