1. In the back-chip test stage, wafer cp test verifies the perfect combination of package circuit chip development , FT test verifies the stability of chip development , and ESD test ensures the safety of the chip. And reliability testInspection and testing, like the ultimate acceptance of the work, every link is related to whether the chip can win praise and trust in the market. Every step is crucial, every step is full of challenges.
2, chip development, like creating a piece of scientific and technological art, its process is delicate and challenging. First of all, the specification definition is the blueprint for creation, which requires a deep understanding of market needs and precise setting of the functions and performance of the chip. This involves not only evaluating the feasibility of the technology, but also considering multiple dimensions such as cost, power consumption, security and robustness.
3, then is the most important part of the production of chipsPhotolithography. Using some special chemicals, which dissolve when exposed to ultraviolet light, we get the shape we need. Then, by using an etching machine to implant ions on the exposed silicon, the corresponding P and N semiconductors are formed, and the above process is repeated to make a three-dimensional structure. 4. Researchers at Fujitsu have developed an experimental quantum chip that they say can perform up to a trillion calculations per second. Existing supercomputers are limited to a few hundred billion calculations per second. The electrons in this quantum chip need very little current to jump from one place to anotherTo another part, so its power consumption is also negligible.
5, the entire chip manufacturing process to use a large number of fine optical technology, material technology and precision processing technology, any of which is indispensable. The high precision lithography machine here is the most important thing in the entire chip production process.
Interestingly, three in the troubled auto industryIn the case of more than years of lack of core problems have been alleviated, major car brands have been scrambling to enter the core. According to incomplete statistics, at present, more than a dozen Oems in China have entered the chip field through self-research, cooperative research and development or investment. The word "swarm" is not too strong.
The Kirin chip is jammed, and various scenarios are cut off and shielded, everyone can see that without their own local chips to support, without our own Great Wall of science and technology, there will be no freedom and autonomy of future science and technology. In the smart phone industry, our local enterprises have chip research and development capabilities,Only a handful. However, with the increasing influence of domestic mobile phone brands, it is more and more unsafe to put this key component of the chip in the hands of others, because it may be jammed at any time, so even these brands are determined to do their own chips.
"Stuck neck" is the "encouragement" to force efforts! While closely following the international pace, domestic core making is also a breakthrough in exploring new directions! -- Graphene technology can be said to have started at the same time around the world.
The baseband used by the Surging S1 chip produced by Xiaomi at that year is the base of the coreBand, the performance of the baseband is very weak, as shown below, and several other basebands can not be compared.
On the one hand, the huge market size of the chip market has attracted the attention of Internet manufacturers, and the current "lack of core tide" and "jam neck" threat, Internet manufacturers have to build cores. On the other hand, the development of the chip industry chain is becoming more and more mature, and the cost of core making is reduced, and the deep development of cloud computing and other businesses is inseparable from the blessing of chips. Throughout the Internet, people with names are not "making core", or on the way to "making core".
OPPO has the ability, the technology, and the choice is the image computing unit and AI computing unit, the two most difficult self-developed IP, regardless of OPPOHow the final effect of the chip is, the difficulty of the two units is not hard to see the determination of OPPO core making and the gold content of this NPU chip is still relatively high. Chinese smartphone maker OPPO is accelerating its drive to develop its own chips to reduce dependence on overseas suppliers and build a competitive edge in the international market.
At the 2021 Future Technology Conference (OPPO InnoDay 2021), OPPO solemnly launched the first self-developed chip Mariana
