Chapter 83 CMOS process technology is mature

"Thirty-six brethren."

"More than thirty? There are not so many people in my yard, so Zhang Ke told Han Laosan to recruit them into a security company to provide security services and regional security for merchants in this area, and I will choose a few reliable ones to watch in that yard, so be it. After Ling Shizhe finished speaking, he sat down.

"Thank you, Seventh Young Master, thank you, Seventh Young Master." After Chen Gengniu thanked him, he took his little brother away with interest.

This kind of thing doesn't matter if Ling Shizhe bothers for him, after arranging them, he doesn't need to take care of them, and the people below will deal with it. I was very hungry after not eating for most of the day, smelling the aroma of the food on the table, picking up the chopsticks, and after greeting Mark and Bai Lu, I ate a large piece.

It's been a long time since I've eaten such authentic Sichuan food, and Ling Shizhe's appetite is also open.

After being full of wine and food, Ling Shizhe first sent Bai Lu home, then sent Mark home, and finally went to Yan Xiaoyun's house by himself.

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Mark got three pieces of information from Ling Shizhe, after a few days of detailed research, he was very interested in the 3.5-inch floppy drive and floppy disk in the data, he decided to start with the floppy disk, and then step by step in making these machines, he found a few assistants from the laboratory, and began to tackle the sketches of the floppy drive drawn by Ling Shizhe.

The first is a floppy disk, this floppy disk is 3.5 inches, the structure is very simple, with a double-sided reading and writing window, the outer packaging should use a hard plastic shell, with an anti-miswriting device.

Although the structure is simple, the difficulty is not in its structure, but in the materials used in the floppy disk, the preparation of magnetic materials, the preparation of magnetic recording media, and the magnetic head material are the core of the floppy drive.

Magnetic materials, the main material is iron oxide, this material has a wide range of sources, can be obtained in large quantities from the pickling pond of Hong Kong steel mills, but now people do not know how to obtain high-purity iron oxide materials cheaply from the pickling waste liquid of steel, the previous method is concentration method and chemical co-precipitation method.

Prepared by concentration method, the fineness of iron oxide particles is not enough to only 20-400 microns, which cannot meet the design requirements of the disk, and the chemical co-precipitation method has serious pollution, and the separation is difficult, the process is more complicated, and the cost is quite high.

Fortunately, the information given by Ling Shizhe mentioned how to cheap high-purity iron oxide method.

Hydrothermal preparation method, a new preparation method, first put iron oxide and M2+ aqueous solution into the solution, stir and then put in a special alkali solution, so as to form a colloidal suspension containing intermediate precipitate in the middle of the solution. Take the intermediate suspension, heat it to a certain temperature, and then blow it into pure air to make it oxidize, when the precipitate disappears, the high-purity iron oxide will be converted.

The cost of hydrothermal preparation is comparable to that of the concentration method, but the particles of iron oxides reach between 0.5 and 1 micron, which is close to the quality of chemical precipitation method.

With this preparation method, the produced iron oxide can be used as an excellent magnetic material for the manufacture of high-density and high-capacity floppy disks. However, it is very inexpensive, only the same cost as low-density floppy disks.

Floppy disks are not unusual, the first floppy disk in history was developed by IBM in 1971, with a diameter of 8 inches.

In 1981, Japan's Sony Corporation first launched a 3.5-inch floppy disk, Apple began to use a 3.5-inch floppy disk in Mac machines in 1984, with a capacity of less than 1MB at this time, and later, it was replaced by Japan's Sony 3.5-inch floppy disk with a capacity of 1.44MB, this floppy disk was prevalent in the 80s to 90s, until the 2000s, the 3.5-inch floppy disk was still one of the popular computer devices, and then gradually eliminated.

It's 1971, and this time is the time when IBM launched the world's first floppy disk, presumably they have launched it, after all, the time has entered July, and Mark made the first 3.5-inch floppy disk in late October, and the capacity of the floppy disk is 1.44M.

After the floppy disk was made, Mark began to make floppy drives, and there was no way to seriously lack manpower.

Mark, the director of the Hong Kong laboratory, is often like a university professor of science and technology, and has been training qualified scientific and technological talents, because Hong Kong's qualified scientific and technological talents are seriously insufficient, and its comprehensive quality is much worse than that of the West, which is the sadness of Hong Kong. Due to the serious shortage of scientific and technological talents, Hong Kong's future development can only rely on real estate, international trade, finance and other development methods without any technical content.

Mark also knows this, so the research and development progress of floppy drives and floppy disks is not fast, even with Ling Shizhe's guidance, it took nearly two months to make the first floppy disk, and the floppy drive has not yet started, he is not panicked, many times he lectures to those students in the School of Computer Science, and selects a few qualifications from those students to make up for his R&D team, so that these students can learn theory and practice at the same time.

The head of the floppy drive uses an anisotropic head invented by Ampex in 1970. Its advantages are small working clearance, steep magnetic field distribution, and narrow magnetic track width, which can well improve the working speed and reading accuracy.

Historically, after Ampex invented this head, it has not been adopted by other companies, but it was adopted by Ambrera in this time and space, and Ambre, the president of Ampex, attaches great importance to this business, and has lined up 3 technicians to make technical support for the floppy drive that Mark is developing.

Ling Shizhe also thought about buying Ampex, but when he learned that Ampex also produced electric motors and radar accessories for General Electric, he dismissed the idea of acquiring. Just kidding, the company that produces radar accessories, no matter how small the Ampex company is, is not something that he, an outsider, can touch, the radar is too sensitive, and he doesn't even dare to have the idea of investing in shares.

Time entered 72 years in February, Mark finally made a floppy drive, and sent a report to Ling Shizhe, asking it to be produced and put on the market as soon as possible, his reason is that although the storage capacity of the solid state drive is large, it is very costly, before the price has not become cheap, the market capacity is quite limited, generally only large enterprises and institutions will buy; The price of floppy drives and floppy disks is very cheap, it will be the most important storage tool for people, Mark predicts that for a long time in the future, floppy disks and solid-state drives will be in a state of coexistence, and floppy drives will become an intermediate transmission medium for data storage and output of hard disks.

Seeing Mark's report, Ling Shizhe realized that he had overlooked a key device in the blade server, that is, a floppy drive.

As we all know, to enter data into the computer, there must be a device that can read and write, this device is a floppy drive or optical drive, in the 21st century, network technology has become extremely developed, many computers have canceled the optical drive, you need to download data directly on the network download, to output data directly with the USB disk, the optical drive is not many people use it at all, the floppy drive has long been eliminated.

The world's first 5.2-inch floppy drive for reading and writing equipment was developed in 1976 by Shugartassociates for IBM's mainframes. It's only 1972, and it hasn't come out yet, and without a floppy drive, the computer can't read and write data.

Realizing his mistake, Ling Shizhe immediately began to remedy it, sending two floppy drive samples and 100 floppy disks to a laboratory in North America, requesting that the floppy drive developed by the Hong Kong laboratory be used as a reading and writing device for blade computers.

When the North American laboratory sent a fax, the floppy drive had been received, and supporting research was underway, Ling Shizhe breathed a long sigh of relief, and he had forgotten such an important device as a reading and writing device. Ay! The mistake of empiricism was made.

Although the floppy drive has been made, Ling Shizhe is currently unable to put him into production, because the driver chip of the floppy drive cannot find a place to produce, and the existing chip factory cannot free up any production capacity. Now we can't find a company willing to do OEM for us, and they all have their own chip production tasks.

Now Ling Shizhe has put all his hopes on the new wafer production equipment and the new CMOS process chip production line, I don't know what happened to them after so long? It's been so long, and I should have gone to see it.

Thinking of this, Ling Shizhe drove to the process laboratory next to the Hong Kong Computer Institute.

"Xiaoling, the new chip process production line, CMOS process technology has finally matured and finalized, and is waiting to send orders to various processing plants." Wang Haihua saw Ling Shizhe coming over to know his intentions, and before he could ask, he said it first.

"Oh, when did it happen?" When he first arrived, he heard a good news, and Ling Shizhe felt that his luck was not bad.

"Yesterday's finalization, the whole set of high-intensity trial operation of the whole process for more than half a year, without any problems, the performance fully meets the design requirements? Yes, this is the test report. Wang Haiwen handed him the report.

Ling Shizhe flipped through the report, looked at it carefully, and nodded, judging from the data, it was quite perfect.

He put the report away and said to Wang Haihua: "Take me to the experimental factory to have a look." ”

The chip laboratory factory is located in Tseung Kwan O near the Kwun Tong Industrial Zone, which Ling Shizhe intends to use as a billion-chip industrial park, and is now negotiating with the Hong Kong government, and it has been almost discussed, and I believe that it will be all over in a month or two.

After coming to the factory, he found that Christopher was also there, changed into a dustproof suit and entered the ultra-clean workshop, looking at the chip production equipment like science fiction, Ling Shizhe nodded secretly.

Christopher acted as a guide and took Ling Shizhe around the factory, looking at the chips being packaged in the observation window, Ling Shizhe said to Wang Haihua: "Professor Wang's new process is very good, it can be developed so quickly, I really want to thank the teachers and students of various universities in Hong Kong." ”

"There, there, Ling Shao is serious, Ling Shaodu has already provided us with relevant information, and it took us more than three years to figure it out, ashamed."

"Three years is a very fast time, which is very much more than I expected, I thought I would have to wait another three years." Ling Shizhe was very happy in his heart, he remembered that it took ten years for Intel to develop CMOS process technology in history, and Wang Haihua and they only took more than three years to get the CMOS process out, which was greatly unexpected by him.

Wang Haihua and Ling Shizhe praised each other, changed the topic and asked: "Ling Shao, this set of technology is a 7-micron process, your factory is still using a 9-micron process, when do you plan to go to 7-microns?" ”

"The equipment is on the production stage, it is now February, it is the off-season for chip sales, and I will take advantage of this time to immediately replace all the equipment in the Canadian factory, and change it one by one, until all the equipment is replaced."

"Upgrading to 7 microns all at once, is that appropriate?" Wang Haiwen was shocked by Ling Shizhe's decision, he just made an upgrade last year, and he will upgrade again at the beginning of this year, and the upgrade range has jumped from 9 microns to 7 microns at once, which is too big.

"Yes, it's very suitable, 7 microns is too far behind, I can't wait to jump to the Angstrom level all at once."

Hearing Ling Shizhe's words, Wang Haihua and Christopher looked at each other, and shook their heads at the same time, this young boss is completely crazy, the whole technology upgrade freak, and he actually wants to skip the nano upgrade to Amy directly, it's crazy.

After thinking about it, Wang Haiwen persuaded and said: "Although the equipment upgrade is good, it can't be done too often, so the cost will be too high, and the gains outweigh the losses." ”

"Professor, you don't understand, you don't understand," Ling Shizhe looked at the chips that were packaged in the window and said: "There is a guy named William H. Davidor in the United States, who once said that if a company wants to always dominate the market, then it must be the first to develop a new generation of products and the first to eliminate its existing products." What I'm doing now is to weed myself out, and Ambrera must always be ahead of the curve in semiconductor technology, and must not be overtaken by those behind us. Our China is too backward, we finally have a world-leading advanced technology in microelectronics technology, it must not be surpassed by the West, Chinese semiconductor people must have the spirit of wildebeest migration, to keep running forward, can not stop, otherwise our only advantage will be gone, either you keep up, or be eliminated; We have been chased, but never overtaken. ”
