After Zhou Yan's laptop was hidden in the snow for a long time, it was finally able to come out for a breath of air. As for its purpose, it was naturally used as a browsing tool to browse the information Zhou Yan had just copied.
The virtual space and system tutorials are still in the cooling-off period of one month after five hundred years of use. Zhou Yan can only give up the idea of further practicing semiconductor technology for the time being and turn to studying purely theoretical things.
In his spare time, Zhou Yan will also conceive of master badge tasks to promote Hanfu.
The original four paintings - "Ode to the Goddess of the Red Sea", "Ladies in the Tang Palace", "Along the River During the Qingming Festival", "Spring Dawn in the Han Palace", and "A Dream of Red Mansions Burial of Flowers" - were already very beautiful, but what Zhou Yan needed to do was
, is to restore a still picture into a dynamic animation.
In order to restore the task on the screen to the greatest extent, in addition to the costumes, which are the top priority, Zhou Yan also needs to first match the characters with steps, movements, and musical instruments that are in line with the characteristics of the era.
Because it was still in the conception stage, and Zhou Yan had more than five hundred years of experience as a reference, it naturally didn’t take much effort.
After the idea was completed, Zhou Yan put the badge task aside for the time being and went back to studying the most basic integrated circuits and photolithography processes of the chip.
Zhou Yan has used transistors, diodes, capacitors, resistors and inductors to build giant electronic computers in space, so he knows very well that integrated circuits are large circuits that combine components such as transistors after being shrunk.
The core of integrated circuits is naturally the etching process of ultra-micro transistors.
The most primitive transistor uses the high-temperature motion characteristics of molecules to form a depletion layer between the p-n electrodes to form an effect field between the two electrodes.
However, after shrinking into an integrated circuit, the three pnp poles of the transistor need to be laid out layer by layer on the etched crystalline silicon wafer, and a special ion process needs to be used in the middle to form a depletion layer. p>
It's just transistors. The integrated circuit also needs to integrate other electrical components such as diodes, capacitors, resistors, etc., which further increases the difficulty of the process.
And, finally, special processes are needed to connect the electrical components with special wires...
If it weren't for the fact that virtual space can automatically generate various elements and ensure the absolute purity of raw materials, Zhou Yan would never study chips. The purity of the materials alone is enough to make the hair on his head turn gray or become bald. Knowing what an integrated circuit is, doesn't mean you can make an integrated circuit.
Before manufacturing, you also need a "tool" with a processing scale of ten nanometers to carve grooves in the crystalline silicon that can accommodate transistors and electronic components.
This "tool" that can process scales up to the nanometer level is called a photolithography machine.
Of course, the processing of integrated circuits does not require a photolithography machine.
No matter how sharp the beam of a photolithography machine is, it cannot carve crystalline silicon. To process grooves on crystalline silicon, you need to use high-purity hydrofluoric acid, which is an extremely corrosive medium.
A few years before his rebirth, Bangzi had a fight with the Japanese and was cut off from the supply of raw materials. He immediately became honest, involving hydrofluoric acid with a purity as high as ten-nine.
In order to ensure that hydrofluoric acid can corrode the places where it should be corroded, you also need a photoresist that can resist hydrofluoric acid corrosion but can be decomposed by light.
The size of the light source of the lithography machine depends on the wavelength of the beam used by the light source. The wavelength of the extreme ultraviolet light source with the earliest wavelength is more than ten nanometers. To achieve ten nanometer level processing, you also need a high-precision light condensing device.
, High-precision light-shielding device-mask...
A set of data has not yet been compiled. Even though he claims to have a photographic memory and can read ten lines at a glance, Zhou Yan is still dizzy when faced with more than ten grams of data. His head is full of various names: mask plate
, photoresist, ultraviolet light source...
Fortunately, the cooling time of the virtual space is only one month.
By the time Zhou Yan had memorized all the information like he was swallowing it, the cooling time of the virtual space was up.
Zhou Yan directly used the points to redeem a hundred years.
After entering the space, Zhou Yan did not rush to manufacture a photolithography machine. Instead, he used the rich mechanical knowledge of the "worker bees" to first create a batch of high-precision measuring instruments.
Next, a batch of machine tools were manufactured, and then they were gradually improved. Colleagues who continued to improve precision also began to add CNC devices to achieve automatic processing.
Although the virtual space can manufacture parts according to Zhou Yan's orders to a certain extent, the shapes are relatively simple and can only be described in Zhou Yan's head. For example, Zhou Yan said he wanted a glass ball with a diameter of one centimeter.
Virtual space can be generated, and it can also ensure that the instruction of the glass ball is one centimeter or one nanometer.
But at a microscopic scale, and the parts are very complex in shape, and the capacity of Zhou Yan's brain is not enough, it is difficult to automatically generate virtual space, and it can only be achieved mechanically.
The next step is the photolithography machine.
Zhou Yan did not plan to reach the nanometer level in one step, so he used 193 nanometer technology, which has been eliminated by many photolithography machine manufacturers. Not only is the manufacturing process relatively simple, but the data is also relatively easy to obtain.
Because all the materials were swallowed whole, during the process of manufacturing the photolithography machine, Zhou Yan could only manufacture and digest the materials at the same time.
When it comes to knowledge in the field of high-energy physics, Zhou Yan has no way to digest it. He can only spend points to exchange books from the system library to study hard. Zhou Yan has been studying the DUV deep ultraviolet light source of the lithography machine for five years. However, sharpening the knife does not waste time cutting wood. After digesting the deep ultraviolet light source, other components of the lithography machine will become much easier.
The lens system of the lithography machine does not need to be processed by Zhou Yan himself. He only needs to know the size and material and directly use the system to generate it. The mechanical mechanism of the lithography machine is relatively troublesome, but with high-precision machine tools, it is nothing.
Question...
After more than thirty years, Zhou Yan finally copied the 193nm lithography machine of a certain artillery factory based on the stolen information.
Next, there are the materials for making chips.
Crystalline silicon is easy to obtain in the virtual space, and even if Zhou Yan uses his own technology to prepare it, it is much simpler than outside: absolute vacuum can be achieved in one sentence, and true pure silicon can be obtained in one sentence...
Finally, there is manufacturing.
To be on the safe side, Zhou Yan came up with another piece of "homework": the 193-nanometer chip technology that a certain Semiconductor Manufacturing Company has eliminated...
It took Zhou Yan fifty years to finally create the 193nm Xeon processor from the toothpaste factory. It took another ten years to create a replica of a 512m memory graphics card, which was then paired with a motherboard.
A server blade with xeon processor as the core comes out.
The next work is relatively simple. Copy the blade servers from the storage device in the virtual space. There are tens of thousands of them at once.
Building a server is even simpler for Zhou Yan, who has become a network security master. He assembles the blade servers like building blocks, pulls out the power cords one by one, and connects them to the sockets provided by the virtual space. p>
As for the gas turbine power plants manufactured in the past, they have all been omitted by the virtual space.
Seeing that there were still more than forty years left, Zhou Yan was no longer in a hurry. He first equipped the server's chip with the copied instruction set, and then perfected the operating system step by step.
To be on the safe side, Zhou Yan uses unix as the operating system.
The last step is to install the 3D film and television production engine "No. 36 Dinghai Zhu" that has achieved the Animation Master Badge reward into the server...
