Hogwarts: Becoming a god from reselling fresh food

"magic."

In the Potion Research Institute, Murphy said, "Our only advantage is magic!"

Sitting in front of him were several experts in the fields of computers and semiconductors.

Murphy stood on the podium in front of them, "I want to build chips. The reason has been told to everyone just now. The improvement of computing power is the cornerstone of future technological development. But everyone can see the potential of computers. The world's top Brains and a lot of capital have been invested in this field."

"We don't lack capital or brains, but we don't have an absolute advantage. But we have something they can't imagine, and that's magic."

"From today on, the chip research team is officially established. You will be responsible for finding ways for magic to work in this project."

"Everyone is an expert in the computer or semiconductor field and is very clear about the chip manufacturing process. I need everyone to open their minds and find a path that can give us a clear advantage over other competitors."

"Do you have any ideas?"

As soon as Murphy finished speaking, someone stood up.

"Dr. Derek Preston." Murphy recognized the other person, "Please speak."

Dai Ruiqi is a slightly fat man in his thirties, "Director, I have an idea. In fact, I had such an idea not long after I came to this institute. I am an algorithm engineer, but I am interested in chips." I have always been very interested in the field. I taught myself IC design and made semiconductor circuits. I also interned in a wafer factory for a period of time..."

"Sorry, I mean, after entering the institute, I have been thinking about how to use magic to make chips. I think there are two spells that may be very useful for making chips."

"That's the enlargement and reduction spells!"

"As we all know, the data that best represents the progress of chip technology is the manufacturing process. At the beginning of this year, Intel launched the 80486 chip, pushing the number of chip transistors to more than one million for the first time. It uses a 1-micron process, which is the most advanced today. Chip manufacturing process.”

"In the UK, the best chip factories can stably mass-produce chips using the 1.5-micron process, which is equivalent to the level of Intel's 80386 chip four years ago."

"Progress in the manufacturing process means more transistors, which means greater computing power." Dai Ruiqi said, "However, every progress in the manufacturing process is very difficult and involves a large number of process improvements, from IC design to photolithography. Machine to doping technology, etching process, photoresist, etc.”

"And this is all because the chip is too small and the transistor is too small. The chip is the pinnacle of human precision manufacturing technology, and the transistor of the chip is the smallest mechanical structure that humans can mass-produce."

"Being able to control the gap between two circuits to 1 micron is an extremely remarkable achievement. The diameter of a human hair is about 50 microns. The 1 micron process is to carve three-dimensional shapes on a scale as thin as a hair. Forty circuits, it’s incredible.”

"But, we have magic. If we enlarge the chip, for example, five times, make the circuit, and then shrink it, the process problem will not be a problem at all!"

"Taking the current 1.5 micron process in the UK as an example, after enlarging it five times, we can use the 1.5 micron process to engrave on a wafer that is 25 times the area. After the engraving is completed, we can then reduce it to the original size. The process It is equivalent to a five-fold reduction, which is a 0.3 micron process! Compared with today’s Intel, it is far ahead.”

"If we use the shrinking spell on the restored wafer to its original size and shrink it another five times, we will directly enter the 60-nanometer process field. According to Moore's Law, we will be at least fifteen years ahead of the world!"

"As far as I know, the magnification and reduction spells vary by more than five times. If we can enlarge the wafer ten times and then reduce it ten times, we will get a 15-nanometer chip. If we can enlarge the wafer twenty times, , and if we shrink it another twenty times, it will be close to the 3-nanometer process! It will not be a problem to lead the world for thirty years!"

In fact, Dairich's statement is not accurate.

Chip performance is not only related to the manufacturing process, but also involves many things such as IC design, materials, spraying process, photolithography technology, packaging process, etc.

Not to mention the quantum tunneling effect that will occur when the manufacturing process reaches less than ten nanometers. It cannot be solved simply by directly shrinking the original chip. New materials and new gate circuit designs are required to overcome it.

Even for a chip with a five-fold process change, it is unlikely that the manufacturing technology under the 1.5 micron process will be directly applied to the enlarged wafer.

But this idea still firmly grasps the most critical bottleneck in chip manufacturing: the minimum size problem of precision manufacturing processes.

"Excellent!" Murphy applauded, "What a great idea! Dr. Preston, I hope you can verify this idea immediately. What do you need?"

In fact, Murphy has long had an idea to use the magnification and reduction spell in chip production, and it is also one of the reasons why he thinks it is possible to make achievements in the chip industry.

However, as a leader, it is not necessary to show your intelligence all the time. Letting subordinates come up with their own ideas will more effectively stimulate their enthusiasm.

"A photolithography machine doesn't need to be particularly advanced, it just needs to be an obsolete process. It also needs the cooperation of a wizard who is good at enlarging spells and reducing spells." As he said that, Dai Ruiqi seemed to have thought of something again, "Yes. Well, we also need a super-clean laboratory.”

Ultra-clean laboratories and photolithography machines are easy to handle and can be purchased with money. But the wizard...

Considering that the soul seed cannot be used as desired, Murphy finally decided to let the house elves assist first.

House elves are also capable of magic, so that should be enough for the time being.

…

After leaving the Magic Research Institute, Murphy came to the Supreme Potion Store in Diagon Alley.

The owner in charge of the store immediately came to greet him, "Boss, why are you here?"

Today's Supreme Potion has already squeezed out several famous potions stores, and has basically completely monopolized the potions business in the British wizarding world. In addition to having branches in Diagon Alley and Knockturn Alley, it also has branches in Hogsmeade. Many wizard gathering places have opened branches.

Murphy naturally couldn't manage so many shops, so he recruited some wizards to take care of the business for him.

Since their salary is linked to their performance, they generally work hard.

The owner of this potion shop in Diagon Alley is a middle-aged man named Isaac Biddle, who is nearly forty years old. He was originally a pharmacist at Slug and Giggs Pharmacy, and he was very skilled. Gao, who was recruited by Murphy after the pharmacy was crushed by Murphy's price war.

"I have something to do, but let's go see the factory first."

The two came to the backyard of the potion shop. Several old dilapidated houses here had been demolished, and four walls had been erected, with blue bricks and red tiles, and a factory building that looked like a nineteenth-century factory had been built.

The space in the factory is much more spacious than it looks from the outside.

In the middle, there is a huge assembly line-like thing. If you look closely, you will see that it is actually a ring-shaped workbench with openings at both ends. There are more than thirty platforms inlaid on the iron tracks, and a crucible is placed on each platform.

There were more than thirty wizards sitting on both sides of the assembly line. There was a crucible in front of each person. The enchanted tracks moved every half a minute, moving the crucible from the previous person to the next person.

The wizards beside the assembly line each held a wand and waved it repeatedly.

They have different jobs. Some are responsible for adding a certain amount of fairy wing powder into the crucible, some are responsible for stirring while dripping morning dew, some are responsible for lighting a fire and heating, some are responsible for picking seven petals from the rose and throwing them in, etc. …

This is actually a production line for beautiful potions.
