I've done whatever I want

Chapter 174 Strong Faith

On that day, Xin Tong, who loves to accept new knowledge, stayed in the CNAS laboratory all day in a law-abiding manner like a primary school student, listening to the laboratory leader Ouyang Xiaoxiao.

This laboratory, which is larger than a basketball court, has powerful functions and includes two parts. One is the reliability laboratory, which is responsible for the environmental stress and aging tests of chips. The employees of Mingyueguang like to call it RA laboratory, and RA is Reliability. Abbreviation, RA laboratory is the reliability laboratory.

The other part is the failure analysis laboratory, which is responsible for the analysis of abnormalities in the chip manufacturing process and customer complaints. The employees of Bright Moonlight like to call it the FA laboratory. FA is the abbreviation of Failure Analysis, and the FA laboratory is the failure analysis laboratory.

The two laboratories are separated independently and connected through a door to form a whole.

As a well-known foreign semiconductor company, Mingyueguang Factory’s report records are bilingual in Chinese and English. The employees inside are proud of speaking a few words of English, even if they spit out a few letters of abbreviation.

Xin Tong spent the morning in the RA laboratory, learned about reliability, listened to Ouyang's little lecture on activation energy and the Arrhenius model, and understood that the service life of the product can be calculated using this acceleration factor formula.

The chip has been verified by the HTOL aging test for 1000 hours, and its life is equivalent to working at room temperature for ten years.

It turns out that the thinking of Westerners is full of speculative models and formulas, and this is how the 49 days came about!This is much more scientific than looking at eight-character fortune-telling.

Seeing that the monitoring current of the 77 chips was consistently stable, he was relieved.

In the afternoon, he followed Ouyang Xiaoxiao to the FA laboratory.

"Manager Xin, look, that's our SEM scanning electron microscope, Scanning Electron Microscope!" Ouyang Xiaoxiao said, pointing to a device with a monitor.

Xin Tong has long heard of SEM, which is the main equipment for FA failure analysis in the factory. However, the laboratory where expensive equipment is gathered is a forbidden area and is not open to the public. Before he was promoted to the project manager, he had no permission to enter the laboratory.

"This Gemini SEM field emission scanning electron microscope can magnify the product to 20 times, and the resolution of the backscattered electron image is 0.8nm, reaching the atomic level. With this equipment, we can analyze the grain surface or fracture morphology. Observation and analysis, any small structural defect can't escape the palm of SEM!" Ouyang Xiaoxiao was beaming with joy when she spoke.

With so many rare treasures in his hand, can Ouyang Xiaoxiao not be floating?
"Is this SEM also an imported device?" Xin Tong asked in a low voice.

"Yes, it is made by German Zeiss company, with original imported equipment! Its working principle is to bombard the surface of the chip with a finely focused electron beam, and the secondary electrons and backscattered electrons generated by the interaction between the electrons and the chip will impact the surface of the chip. Or fracture morphology for observation and analysis.” Ouyang Xiaoxiao seems to be very knowledgeable.

Xin Tong has long heard of Zeiss, a German company that is a pioneering technology leader in the optical and optoelectronic industries worldwide.

The company has so many imported advanced equipment, logically speaking, Xin Tong should be proud, but when he heard that Ouyang Xiaoxiao's novel is a German equipment, instead of feeling a little happy, he frowned , My heart is full of heaviness.

When can domestic products be proud?

"Manager Xin, come and try!" Ouyang Xiaoxiao warmly invited after the introduction.

Xin Tong was born as an engineer in the bonding process, and he is full of love for equipment operation. He doesn't want to miss such advanced equipment, and looks eager to try it.

Under Ouyang's little guidance, he carefully placed a bare chip on the stage, started the equipment, and slowly operated the SEM.

The miracle happened quickly!

Under the scanning electron microscope, the ordinary-looking chip looks like a bustling city, full of streets and dense buildings extending in all directions. The process of chip manufacturing is the process of a city's construction. There is no doubt that this The direct visual impact gave him a deeper understanding of the microscopic chip structure.

"I really didn't expect that the structure of a chip as big as a fingernail is so complicated, and there are so many things!" Xin Tong moved his eyes away from the display screen, and Xin Tong was deeply moved. This was the first time he observed a chip from a microscopic perspective.

"Of course, I heard that it takes hundreds of people to work for several years to design a microprocessor chip like MPC5200!" Ouyang Xiaoxiao was also full of emotion. He observed the chip for many years with a SEM microscope, and he naturally had a speech right.

"Really?" Xin Tong cast his eyes on the display screen again, moved the chip slowly, and found that the chip was infinitely extended, and it was so big that it was boundless. He suddenly had a desire to gallop.

Taking his eyes away from the screen again, he looked at the small silver grain on the objective stage, and said softly: "Under the scanning electron microscope, I feel that this chip seems to be magical, just like the Tathagata Buddha. Like the palm of your hand, it grows infinitely, and Sun Wukong can't do anything with a somersault!"

Hearing Xin Tong talking about magic and mentioning Sun Wukong Tathagata Buddha Lord, Ouyang Xiaoxiao couldn't help laughing.

"It's not easy! It's not easy!" Whether it's design or manufacturing, chips are a miracle in human history!Xin Tong was shocked.

"It's not easy. Just think about it. Hundreds of people have worked crazily for several years for a single chip to solve thousands of bugs. They are not designing chips, they are building a magnificent Great Wall!" Ouyang Xiaoxiao Also said with emotion.

Xin Tong's expression suddenly became serious. All his life, he was born for chips!
Choosing chips as the career that you have dedicated your life to is choosing a life journey full of thorns!
He suddenly had some understanding of the behavior of the design lunatic Yuan Chengxu who believed in Buddhism.

With such a complex chip structure, bugs are prone to appear in the design process. Designers need 996, day and night, without strong beliefs. This is an impossible design task.

Believing in Buddhism is also a kind of faith!
When he was about to get off work, he returned to the RA laboratory again, staring affectionately at the chips lying flat in the aging furnace, and suddenly felt that those chips were like his own gourd baby children, innocent and cute, he had a feeling that he wanted to touch them The impulse of their faces!

Sorry to make you suffer in the stove!

After walking out of the laboratory, what surprised him was that the production workshop was much quieter, and the scene of chattering in groups in the morning was gone.

The sudden change of the environment quickly caught Xin Tong's attention. It seemed that the precarious situation in the production department had been sorted out. He had been busy in the laboratory all day, but he didn't know what happened in the production department.

He suddenly remembered his old classmate Jiang Hua, and hurried towards the office of the production department.
