"Ah, cut -"
Far away in an underground building on Hong Kong Island, Chen Yi sneezed, rubbed his nose and muttered: "Which guy is always scolding me?"
After complaining, he continued to devote himself to his work.
At this time, he was in a dust-free factory, wearing a white isolation suit. The workbench in front of him was covered with transparent glass like an exhibition stand. The inside of the workbench must be vacuum.
The environmental control of the dust-free workroom is also extremely strict. Not only this room, but also all the rooms in this area add up to a total of 10,000 square meters in a dust-free zone.
The control accuracy of air pollution sources must be at least 1,000 times that of the outside world, and the temperature and humidity must be kept constant. The development of the environmental control system in this workshop alone cost Chen Yi almost 100 million dollars.
Not counting R&D costs, the entire dust-free work area cost five thousand dollars per square meter. Well, it was much cheaper than the first-tier housing prices in his previous life, which made him very happy.
Moreover, it is underground, so the construction is difficult, and it is still constructed manually, so it is so expensive. Now that Legion and Xuanyuan Goudan are in place, the cost has been reduced by at least five times.
At this time, Chen Yi was operating on the screen in front of the workbench. Inside the glass cover was a strange and simple light-condensing system, unlike those composed of winding cookie pipes and many lenses for refraction, reflection, and concentration. Light source system, yes, this is the light source system used for lithography machines.
However, the light source system in front of Chen Yi is completely different from the mainstream light source system of Blue Star. The entire system only consists of three important parts: the laser transmitter, the laser target injection tube, and the flat trapezoidal crystal.
The key to this system lies in this trapezoidal crystal. The light source system designed by Chen Yixin integrates a structure composed of multiple lenses and prisms into this isosceles trapezoidal crystal with a median line of 50 centimeters and a height of 10 centimeters. This is a very, very, very sophisticated system. The important "very" must be said three times.
The principle of the photolithography machine is very simple. In fact, it is similar to a SLR. It can be said to be an enlarged version of a SLR. The integrated circuit graphics designed on the photomask are exposed to light through the lens module and printed onto the photosensitive material to form a pattern. However, The accuracy is measured in nanometers, and everyone knows the difficulty.
Especially for the working accuracy of extreme ultraviolet lithography machines, according to a very down-to-earth metaphor from Chen Yi's previous life: two supersonic aircraft are flying at the same speed in the sky and are very close to each other. At this time, they need to stand On the wing of one plane, a blade was used to carve a beautiful landscape painting on the surface of a grain of rice on the wing of another plane.
Of course, Chen Yi is not that awesome yet, and he can now build an extreme ultraviolet lithography machine.
In the previous life, the giants of the Blue Star chip industry found that the 193nm deep ultraviolet light manufacturing process was reaching its limit, so they turned their attention to ultra-short wavelength extreme ultraviolet light.
The development of extreme ultraviolet lithography machines began in 1997. The United States took the lead and gathered the strength of dozens of countries to work on it for almost twenty years. The first sample was officially released in 2017. You can imagine the difficulty of this.
An extreme ultraviolet lithography machine is mainly composed of four parts: an extreme ultraviolet light source, a reflection projection system, a photolithography template, and a photoresist that is sensitive to extreme ultraviolet light.
However, no matter which part of the traditional photolithography machine manufacturing process is used, it has to be redesigned and developed.
Now Chen Yi has just made a breakthrough in the light source system by cheating and adding prophet, and has advanced the research and development process of the reflection projection system a big step. During this time, Chen Yi has more physical skills in his skill bar. A subcategory: Optics.
What Chen Yi did was to simplify the complex refraction and reflection structure composed of multiple lenses and prisms, and integrate it into a special crystal. The specific method was to use laser engraving on a specially processed piece of crystal. A specific lens module is carved into the glass.
His design ideas for photosensitive components are different from the mainstream ideas of previous Blue Star cameras. In fact, the technology of previous Blue Star cameras has not changed much. It is just a simple improvement of lens technology and the use of more lenses.
Later, the rise of smartphone cameras completely crushed the camera industry. Except for the SLR, which is known as the threshold of photography, and still maintains its competitiveness, other cameras have been beaten to the ground by smartphones.
Because SLR lenses are awesome, but they are extremely expensive.
But this is still just a pure technological iteration. Just like when Chen Yigang traveled through time, major manufacturers were too embarrassed to show off their new products without five or six cameras on the back.
In fact, the principle of multi-camera imaging technology is to combine the photos taken by multiple cameras, collect the high-quality parts of each photo, improve the average score, and then combine them into one high-quality photo.
Chen Yi's idea is very simple. Is there a lens that can achieve the effect of multi-lens imaging?
In fact, there is, and it existed before humans appeared, that is, the compound eyes of insects. In fact, the inspiration for multi-lens imaging technology came from compound eyes.
A compound eye is a sensory organ composed of an indefinite number of small eyes. However, due to cost issues, Blue Star has not considered integrating several lenses into one lens to achieve a true compound eye structure, but Chen Yi is not afraid. Burning money, he has more money now.
This was also the inspiration that Chen Yi got from the panel data summary. He mentioned this idea to the chip alliance, and everyone began a vigorous research and development process to achieve miracles. The main purpose was to increase the number of photosensitive components and lenses. Compressed into one.
After a period of tinkering, everyone actually came up with a novel design - honeycomb lens. The lens is composed of numerous hexagonal lattice. At first glance, isn't this the same beauty institution that Chen Yi used in his previous life? The honeycomb laser lens you made?
However, if you look closely, you will find that the two are completely different. It seems that there are many hexagonal grids carved on the lens, but in fact, these grids are inside the lens.
Each grid is equivalent to a lens, with different heights, sizes, and light transmittances. These are all carefully calculated.
Of course, it is sheer nonsense to rely on traditional processing techniques to grind such lenses, because the surface concavities and convexities of the lenses corresponding to these large and small hexagonal grids are all different. If you really have to grind them one by one, don't I wonder if there are such awesome people in Blue Star? They don’t even have such awesome machines.
Chen Yi came up with a way. Since the electricity bill is free now, he went directly to laser printing and used laser internal engraving technology to engrave the inside of the special crystal.
First, a three-dimensional structure is calculated, and then layers of hexagonal grids are printed internally as lenses.
In this way, the continuous refraction and reflection of light can be controlled through the three-dimensional structure composed of all lenses and the remaining parts of the crystal, which can be used to control the light to achieve the desired result. This is the honeycomb three-dimensional lens set.
After the successful development of the honeycomb stereo lens set, the difficulty of developing extreme ultraviolet light sources has been greatly reduced, and it can already be applied in many industries. The first applications are laser weapons and machine vision.
Especially for Kira, Dawn Society will usher in a new round of industrial upgrading, and Keyence, her biggest competitor in Japan, is no longer a concern.
After experiments, under the same power of light source, the irradiation power of the laser instrument using the honeycomb stereo lens group is more than twice that of the conventional lens. Moreover, this is only the honeycomb stereo lens group that has just been successfully developed, and there is still a lot of room for improvement. .
With further research and development and continued optimization of the structure, the laser irradiation power of traditional lenses under the same light source will increase geometrically.
So a certain sea in Yanjing exploded again, and various vests in the gold market once again increased their gold sweeps. Oh, and now the price of gold has increased by half compared to the initial price.
Chen Yi doesn't need to worry about other industrial applications for the time being. A lot of companies and institutions in the mainland are opening up their imaginations. There are already a lot of various results in the laboratory, all waiting there. After finalization, large-scale promotion and application will be carried out.
