The world's richest man started by developing gutter oil

This time LeTV successfully sold 10 futures mobile phones within ten minutes.

You heard correctly that it is a futures mobile phone, not a spot mobile phone. These mobile phones will not be delivered until December 12th. It is not that Deep Blue Electronics Factory is slow in OEM production, but that LeTV has just finalized the foundry contract with Deep Blue Electronics Factory not long ago.

You must know that the Snapdragon 800 was only released in early September, and it only took LeTV more than 9 months from the decision to the release.

However, everyone can imagine the quality of the mobile phones developed in such a short period of time.

The only advantage of LeTV 2pro is that it is very cheap.

However, when friends learned about the price of LeTV 2pro, they were confused. Everyone wanted to take advantage of Deep Blue's disappearance and make a profit. LeTV had to reconsider the pricing of the new mobile phone.

At this time, all mobile phone friends and merchants hated Accountant Jia for being such a troublemaker.

LeTV headquarters building.

Accountant Jia was delighted when he saw the data on the background.

These 100,000 mobile phones are just the beginning. The first batch of LeTV Pro sold only 100,000 units. One reason is that LeTV sells futures, and the other reason is that Accountant Jia learned Rebus’ hunger marketing.

Accountant Jia immediately picked up the mobile phone on the table and dialed the number of operations director Zhou Yujun.

"Mr. Jia." Zhou Yujun greeted after answering the phone.

"Your operations department is preparing to start the second pre-sale in three days." Accountant Jia said.

"Okay, Mr. Jia." Zhou Yujun replied.

September 2012, 12, China time.

In the blink of an eye, more than half a month has passed. Last night, Fruit released the iPhone 6. The first-day pre-orders for the iPhone 6 exceeded 500 million. The sales volume in this life is even more exaggerated than in the previous life. The first-day pre-orders for the iPhone 6 in the previous life were only 400 million.

Judging from the first-day sales data of iPhone 6 alone, iPhone will become the best-selling mobile phone in the next year.

All mobile phone manufacturers were so envious after learning about Deep Blue's sales volume.

Shenlan Group Nantian Pioneer Park X-ray lithography machine laboratory.

Han Chen and a group of researchers are standing in front of a machine that is three meters long, two meters wide, and two meters high. Because the internal parts of the circuit without a shell are all exposed to the air, this machine is what Han Chen has been studying. X-ray lithography machine.

At this moment, the staff is installing the power supply and transformer for the X-ray lithography machine.

"Mr. Han, the power supply is installed." said Liu Guorong, the researcher responsible for installing the power supply and transformer.

"Very good, turn on the power." Han Chen said.

After speaking, Han Chen and a group of people walked to the console aside. As the power was turned on, a picture appeared on the console. Soon the console entered the operation interface. The operation interface of the lithography machine is also very simple. You can understand it with a little training. How to operate.

Han Chen operated the mouse and pressed the button on the operation interface to let the lithography machine enter vacuum charging.

As the machine operates, the air in the lithography cabin is removed by the vacuum pump, and the pipe on the other side injects nitrogen into the vacuum chamber.

"Feng Xianliang, put the wafer into the cabin." Han Chen said.

"Okay, Mr. Han." Feng Xianliang said, standing behind Han Chen.

Then Feng Xianliang pushed a cart toward the lithography machine. After a while, he came to the feed port on the right side of the lithography machine. The feed port popped out under Han Chen's operation. Feng Xianliang put the wafer in into the feed port.

"Mr. Han, the wafers have been sent into the cabin." Feng Xianliang said.

"Okay." Han Chen replied.

Han Chen then imported the chip drawings into the system and pressed the start button of the lithography machine.

Although the cabin of the lithography machine is vacuum-sealed, there is a camera installed inside the cabin, through which the situation inside the cabin can be viewed. The laser head hits the X-rays on the wafer according to a preset program.

As the machine is running, the staff now become nervous, but it is useless no matter how anxious they are now, because the processing speed of the X-ray lithography machine is very slow.

Because this X-ray lithography machine takes 8 minutes to process an 5-inch wafer, which means that an X-ray lithography machine can process up to 12 wafers in an hour.

Compared with the DVU lithography machines of AMSL, Canon, and Nikon, there is a huge difference. The DUV lithography machines developed by these manufacturers can process 100 wafers per hour, and the efficiency is more than 9 times that of X-ray lithography machines.

Regardless of the slow efficiency of the X-ray lithography machine developed by Han Chen, it is much more powerful than the existing DUV lithography machine.

The cost of an X-ray lithography machine is only 58 yuan. In addition, the power consumption of an X-ray lithography machine is lower than that of a DUV. The power consumption of making a wafer is only 58% of that of a DUV. The most important thing is that it does not A mask needs to be made.

If the efficiency is not enough, it depends on the quantity. One machine can produce 1 pieces in one hour, and 12 machines can produce 10 pieces in one hour.

A DUV lithography machine costs tens of millions of coins, and 10 X-ray lithography machines only cost 580 million coins.

It can be said that X-ray lithography machines completely beat existing DUV lithography machines in other aspects except efficiency. However, EUV lithography machines cannot compare with X-ray lithography machines.

The best thing about the X-ray lithography machine is that it is very simple to upgrade and iterate. In the future, you only need to upgrade the existing laser head. The cost of upgrading a piece of equipment is less than 10 soft sister coins.

Although the X-ray lithography machine only needs to upgrade the laser head, the production of the laser head of the X-ray lithography machine is very complicated, but the research and development cost of the laser head is not lower than that of the DUV lithography machine.

X-ray lithography machines only have relatively low production costs after mass production.

Five minutes later, a wafer was transferred out of the lithography machine warehouse, but Han Chen and others were not in a hurry to touch it. If they wanted to know whether there was a problem with the lithography machine, more samples would be needed for testing.

An hour passed in the blink of an eye.

The X-ray lithography machine successfully sent 12 wafers out of the lithography machine cabin. "Duan Zhenyuan, send these wafers for etching and let me know when the results come out." Han Chen said.

"Okay, Mr. Han." Duan Zhenyuan replied.

Although the photolithography machine has engraved the circuit on the wafer, there are still many processes waiting for it.

For example, etching requires the use of liquid, gas or plasma methods to remove the excess part of the oxide layer, leaving only the part covered by the photolithography pattern. The etching process is usually divided into wet etching and dry etching. The former uses a specific chemical solution to perform a chemical reaction, and the latter uses gas or plasma to perform a physical or chemical reaction.

The next step is ion implantation, which requires the use of high-energy ion beams to inject dopants into specific areas of the wafer to change its conductive properties. The ion implantation process can control the type, size and performance of transistors.

These steps are just the front-end production. To complete the front-end production, you need to do the back-end production. The back-end production needs deposition, photolithography, etching, and filling.

Deposition requires depositing a layer of insulating material, called a "dielectric layer," on the surface of the wafer. Dielectric layers prevent current interference and crosstalk between metal lines. The deposition process usually uses methods such as chemical vapor deposition, atomic layer deposition or physical vapor deposition to form a uniform and defect-free film on the wafer surface.

Photolithography requires repeating the photolithography process in the front-end production, coating the dielectric layer with photoresist, and exposing it with a mask and light source to leave the desired pattern on the dielectric layer.

Etching requires repeating the etching process in the previous stage of production to remove the excess part of the dielectric layer, leaving only the part covered by the photolithography pattern. This forms holes in the dielectric layer, called "vias" or "contact holes."

Filling requires filling through holes or contact holes with metallic materials (such as copper, tungsten, etc.) to achieve connections between transistors. The filling process usually uses methods such as electroplating or chemical vapor deposition to form metal lines in vias or contact holes.

After the front-end and rear-end production is completed, the chip must be inspected. The inspection process is divided into four steps. The first step is electrical parameter monitoring, the second step is wafer aging test, and the third step is wafer sorting. , the last step is encapsulation.

Electrical parameter monitoring requires monitoring the electrical parameters of the wafer, that is, measuring the electrical characteristics of various devices and structures on the wafer, such as threshold voltage, leakage current, contact resistance, etc. EPM can evaluate whether there are abnormalities or deviations in the chip manufacturing process and the impact on chip performance and reliability.

Wafer aging testing requires aging testing of wafers, that is, stress testing the wafers under extreme conditions such as high temperature, high pressure, or high frequency to simulate various stresses that the chip may encounter in actual use environments. Burn-in testing can evaluate the stability and longevity of a chip, as well as predict possible failures.

Wafer sorting requires sorting wafers, that is, using special equipment to test the function and performance of each chip on the wafer to screen out qualified chips and unqualified chips. The sorting process can divide qualified chips into different categories and batches according to their grade and needs.

Packaging requires encapsulating qualified chips, that is, connecting the chips to external pins or pads, and wrapping them with materials such as plastic, ceramics, or metals to protect the chips from physical, chemical, or electromagnetic interference. The packaging process can choose different packaging forms and technologies according to the type and application of the chip.

These steps take about three to four weeks to complete. If there are no problems with the manufactured chips, then the X-ray lithography machine is considered a success. If there are problems, the equipment must be improved.

However, the time it takes to improve the X-ray lithography machine is unknown. The fastest one may be solved in a week or two, while the slower one depends on where the problem lies.

After Han Chen returned to the office, he called Yin Zhengbang, the head of the wafer factory, to the office.

After a while, a man in his forties opened the door of Han Chen's office. The man was dressed in a white shirt and black trousers. The man was Yin Zhengbang, the director of Deep Blue Wafer Factory.

Yin Zhengbang is the deputy director hired by Deep Blue from Huahong Semiconductor two months ago.

"When will the fab equipment arrive?" Han Chen asked.

"Mr. Han, the relevant equipment will be delivered in February next year, and the relevant production raw materials have been booked. Because the raw materials are relatively abundant, the manufacturer can deliver it to your door at any time. The fluorinated acid you asked me to reserve is already here. Reserved." Yin Zhengbang said.

In addition to photolithography machines, chip production also requires etching machines, ion implanters, polishing machines, grinding machines, slicing machines, packaging machines and other equipment.

Equipment such as etching machines, polishing machines, grinders, slicing machines, and packaging machines can all be purchased domestically.

Only ion implanters can only be purchased from abroad. In order to avoid attracting the attention of Black Rock Group, Han Chen registered a company in Hong Kong Island in the name of Kong Huimin, and then used this company to purchase ion implanters.

Fortunately, the ion implanter is a restricted equipment, so the ordering process was very smooth.

"When can the fab come in?" Han Chen asked.

"The wafer fab is already undergoing dust-free decoration, and it won't be able to enter the site until March next year at the earliest." Yin Zhengbang said.

"Okay, then you go and do your business." Han Chen said.

After listening to Yin Zhengbang's report, Han Chen already had a rough idea of ​​when the wafer fab would be launched.

According to the current situation, the wafer plant will not be ready until June next year at the earliest, and the Deep Blue Group will not be able to produce its own chips until August next year at the earliest.

Fast forward to November 2013, 2.

In the past period of time, major mobile phone brands have launched their new mobile phones.

According to the original plan, we were going to launch it around April this year. Because LeTV, a troublemaker, launched new mobile phones in advance, other manufacturers could only launch their own mobile phones in advance.

Among many mobile phone brands, three companies use self-developed chips.

The first company is the Fruit Company, the second company is Bangzishanxing, and the third company is Warwick Company.

The performance of the CPU independently developed by Warwick is very similar to that of MediaTek's CPU. I don't know if it is because of the experience of Deep Blue Group. Warwick is very low-key in marketing and does not promote their products.

Although Huawei is very low-key in terms of marketing, their sales are not bad at all. Their marketing method is to cooperate with operators. The mid-to-low-end contract phones promoted by operators are basically Huawei.

Deep Blue Semiconductor in Nantian Pioneer Park.

Display processor department.

This is the second year that Pascal Banning has been working at Deep Blue Semiconductor. In the past two years, they have developed many products, but Deep Blue has not produced any of the products they developed after being banned.

Since Deep Blue was banned, Pascal Banning began to worry about whether the company would ax the semiconductor department because of this incident.

What surprised him was that Deep Blue Group did not lay off any employees due to the ban.

Normally, no matter which company encounters this kind of thing, it will definitely eliminate useless departments and eliminate the right departments. Deep Blue not only did not lay off employees, but also strongly encouraged chip research and development. This incident left Pascal Banning a little confused.

The annual salary offered by Deep Blue is not low, and the company has not proposed layoffs, so Pascal Banning and his team have been working until now. (End of chapter)
