A student majoring in microelectronics, if he has not read the book "Electrons and Holes in Semiconductors", it is incredible, and the place where Zhang Heng and others visited next is related to the author of this book.

His father is a mining engineer who graduated from MIT, knows 8 Chinese, and his mother is the first female mineral surveyor in American history, graduated from Stanford.

After receiving his Ph.D. from MIT, Shockley joined the then-world-famous Bell Labs, where two scientists led a team of scientists who fabricated the first germanium transistor in human history on December 23, 1947, marking the beginning of the semiconductor age.

Due to patent conflicts, Shockley, who was the head of the experiment, did not get the signature of the inventor of the germanium transistor's patent, so he held his breath and worked hard, and finally two years later, he independently manufactured the first junction transistor (PN diode), completely justifying his name.

In 1956, Shockley and two of Bell Labs' henchmen were awarded the Nobel Prize in Physics for their invention of the transistor.

Earlier in the same year, the Shockley Semiconductor Laboratory, funded by Beckman and headed by Shockley, was established in Palo Alto Lookout Mountain, which immediately attracted countless top talents from all over the United States to join.

However, at this time, in front of Zhang Heng and the others, it was only a slightly dilapidated warehouse, if it weren't for that special map, they wouldn't have been able to find this place at all.

Shockley was a good scientist, but not a good business manager, and the management methods and business strategies he adopted in the company ended up hurting all the employees, who were attracted to him because of their admiration and admiration.

In October 1957, eight scientists, who were later angrily denounced by Shockley as the "Eight Rebels," resigned from Shockley and founded Fairchild Semiconductor the next day, just 1.5 miles from Shockley's lab.

It's ruthless!

The story of "Eight Rebellions" will continue to be exciting.

Eight Rebellion has created many epic achievements in Fairchild, such as the first silicon transistor and the first silicon wafer integrated circuit, which has made the parent company Fairchild Photographic Equipment Company a huge profit.

However, due to equity and management reasons, the eight rebels parted ways one after another, and they and other scientific researchers who also ran away from Fairchild Semiconductor embarked on their own bullish life paths.

As a result, Fairchild became known as the "West Point Military Academy of Silicon Valley", and at a semiconductor industry symposium in Silicon Valley in 1969, only 24 of the 400 attendees had not worked at Fairchild.

Fairchild Semiconductor, located at No. 844 Charleston Road at the foot of Lookout Mountain, is still operating reasonably well at this time, Zhang Heng and a few people stayed at the door of the company for a while, got in the car and rushed to the last destination of the day, INTEL (Intel).

In the first half of 1968, Robert Noyce, the main founder, helmsman, and spiritual leader of Fairchild Semiconductor, the eldest brother of the Eight Rebellions, submitted his resignation to the board of directors of the parent company and left the company he had helped found.

A week later, Gordon Moore, the lab director who had followed him all his life, also left Fairchild, followed by deputy director Andy Grove.

On July 18 of the same year, Intel Corporation officially opened, co-founders are Arthur Locke, Robert Noyce, Gordon Moore, the company's name comes from the suggestion of Noyce's daughter, is an abbreviation of integrated electronic words.

I don't know if these people are all temperamental, or if this hill is no more than 100 meters high has good feng shui, Intel's address also chose to be near Lookout Mountain, not far from Shockley Lab and Fairchild Semiconductor.

At 16 o'clock in the afternoon of January 2, 1973, there were two people who received Zhang Heng in the small reception room of Intel, Federico Fagin, an engineer in the R&D department, and Edward Gherbo, the head of the sales department.

The latter jumped from TI (Texas Instruments) to Intel last year to replace Bob Graham, the former sales executive who was forced out by Andy Grove because he had no technical background, and it is clear from this incident that Grove has successfully established his strong style at Intel.

Gerbo personally came forward, because Zhang Heng told Intel's procurement plan on the phone in the afternoon, 500 sets of 8008 chips and supporting systems, as the new sales executive, it is of great significance to be able to open up another sales line.

At this time, the vast majority of Intel's profits came from its legendary DRAM chip, which easily occupied all the application market at this time with almost no competitors, and will maintain a good time for nearly 10 years until RB people enter this market.

Within Intel, however, there is another group of engineers who are strongly advocating the development of higher-performance microprocessor chips based on the existing 4004 and 8008 in an effort to create new revenue streams.

Fajin in front of Zhang Heng is the representative of this group of engineers, because he is the actual person in charge of 4004 and 8008, after his supervisor Ted Hough completed the design of the chip instruction set of 4004, this skilled immigrant from Italy undertook most of the remaining work: designing circuits, making layouts, building systems, and debugging and testing.

Andy Grove's biography of Intel written in the 80s recorded that the circuit diagrams, layouts, and PCB wiring diagrams of the 4004 system were all hand-drawn by Farkin, and the only tools were pencils and rulers.

One can imagine how deep this person's obsession with the development of microprocessors must be.

However, it is precisely because of the boom of DRAM and other memories that Intel's senior management, including President Noyce, does not care too much about the microprocessor market, and they believe that 4004 and 8008 may only be used in electronic watches and rice cookers, and there is no huge high-profit application market to support these two chips.

At this time, there is an unwritten rule within Intel that the estimated gross profit margin of a product must reach 55% before it is worth investing resources in organizing R&D and production.

Faggin was destined to be disappointed, and when he completed the development of Intel's third-generation microprocessor 8080 next year, he would leave his job to join another colleague who also left Intel to found Zilog, and then launched the Z80 in '75.

Around the same time, MOS Technologies, another company founded by a few disappointing Motorola engineers, launched an 8-bit microprocessor MOS6502 that also achieved great results.

The market performance of these two chips, along with Motorola's MC6800 in the next few years, finally aroused the vigilance of Intel's top management, and increased investment in microprocessors, and in 1978 hastily launched the 8086 to steal the market.

"I have placed this order with Intel now, will it affect Intel's R&D policy and change the fate of Fajin?" After the two sides shook hands and got to know each other, Zhang Heng instantly turned this thought in his heart, and he had a headache for a while.

He really didn't want to see this happen, because the engineers in Fajin and the R&D MOS6502 had long been put into the talent pool that he had to recruit and was likely to recruit.

Zhang Heng plans to recruit and integrate these two groups of original talents, integrate the technical advantages of the previous MOS6502 and Z80, design the first general-purpose microprocessor chip, and lay the CPU system belonging to Daheng Technology.

In this way, whether it is arcade machines, electrical appliances, computers or industrial control equipment, Daheng Technology can use the invincible core of its own intellectual property rights.

PS: The job advertisement published in the newspaper was written in binary code, and he also designed the field test questions himself, and interested friends can try to answer one of the questions: 127 people participate in a tennis knockout match, and finally have to play several matches to determine the champion, and the easiest way to get the answer.
