On the same day when ZTE announced that the 5g base station 7Nm chip was commercially available, SMIC International’s second generation FinFET technology happened to make new progress. On October 11, Zhuhai municipal Party Committee organ newspaper Zhuhai Special Zone News reported that IP and customized chip enterprise core technology had completed the world’s first chip assembly and test based on SMIC international FinFET n + 1 advanced technology, and all IP were home-made, and the function test passed at one time. < p > < p > as of press release, SMIC A shares and Hong Kong shares both rose nearly 14%, and semiconductor equipment suppliers such as Zhongwei company, North Huachuang and Anji technology also increased by more than 5%. < p > < p > regarding the N + 1 process, CEO Liang Mengsong of SMIC disclosed last year that the 7Nm process is very similar in terms of power and stability, and does not need EUV lithography machine, but the performance improvement is not enough, so the N + 1 process is oriented to low-power applications. < / P > < p > the so-called successful tape is introduced to the observer network by the Institute of semiconductors of the Chinese Academy of Sciences, which means to get devices with performance up to the target in the laboratory. However, in order to achieve real mass production, the reliability and degradation mechanism of the device still need a lot of data support and repeated verification. < p > < p > in a report entitled “it’s urgent to break through the domestic core”, Zhuhai Special Zone Daily wrote: “the first chip assembly and test of SMIC based on the international advanced technology of SMIC technology is successful, which not only means that the” domestic chip “with independent intellectual property rights has broken the foreign monopoly again, but also shows that the manufacturing technology of 7Nm chip of” domestic version “has been improved Broken. ” < / P > < p > in fact, it is a necessary step before chip mass production. In order to test whether the integrated circuit design is successful, it is necessary to carry out trial production of the chip to verify whether the circuit has the required performance and function. If the tape is successful, the chip can be mass produced in large scale; on the contrary, we need to find out the reasons and optimize the design accordingly. < / P > < p > a relevant person from the Institute of semiconductors of the Chinese Academy of Sciences told the observer network: “before the technology is delivered, there will be a user trial stage. According to different situations, it may be months or years before mass production can be realized.” < / P > < p > just one month ago (September 18), SMIC disclosed that “FinFET n + 1 has entered the customer introduction stage, and is expected to trial produce in small quantities by the end of 2020” in response to investors’ questions in the “Shanghai Stock Exchange E-interaction” < p > < p > in February this year, the joint CEO of SMIC, Liang Mengsong, disclosed for the first time at the financial report meeting that in terms of power and stability, N + 1 and 7Nm processes are very similar, with the only difference in performance, and the improvement of N + 1 process is relatively small. < / P > < p > on specific data, he revealed that compared with 14nm, SMIC’s N + 1 process has a performance improvement of 20% and a power consumption reduction of 57%, while the benchmark performance improvement of 7Nm market should be 35%. Therefore, the company’s N + 1 process is oriented to low-power applications. < / P > < p > prior to this, SMIC ordered an EUV lithography machine from ASML of the Netherlands for the next generation process manufacturing, with a value of up to US $150 million, which was originally planned for delivery in early 2019. But the deal has not yet been completed despite the obstruction of the US government. < / P > < p > as for the query that “the next generation process development cannot be realized without EUV lithography machine”, Liang Mengsong mentioned that in the current plan, EUV equipment will not be used in N + 1 and N + 2 processes, and EUV equipment will not be used in N + 2 process until the equipment is ready. < p > < p > Forbes china.com also pointed out in a report in March this year that SMIC’s 7Nm process development is similar to that of TSMC. There are three kinds of processes developed for 7Nm nodes, namely, low-power N7, high-performance n7p and N7 + using EUV technology. < / P > < p > it should be noted that at present, only TSMC and Samsung can mass produce 7Nm chips in the world. Intel 10nm products of IDM manufacturer have just come into the market soon, and 7Nm chips may be postponed to 2023. This means that SMIC is expected to catch up with Intel in the manufacturing process. < / P > < p > in the news released on the official website, Xindong technology mentioned that since 2019, the company has invested tens of millions of yuan to optimize the design and take the lead in completing the nto production when the core n + 1 process is still immature. The first chip based on N + 1 process has been tested and iterated for several months to help SMIC break through the bottleneck of N + 1 process yield. < / P > < p > the observer’s website found that there were many news related to SMIC international on the official website of Xindong technology. For example, it has been awarded the best partner of SMIC for four consecutive years (2013-2016), the R & D and mass production success of a number of high-speed interface IP based on SMIC’s international 14nm process. < p > < p > according to qixinbao information, Xindong Technology Co., Ltd. was established in July 2006 with a registered capital of 10 million yuan. The controlling shareholder is Ao Jikang, holding 94.8% of the shares. < p > < p > at first, the core technology business was to do optical communication chips, and later transformed to bitcoin mining machine chips. It has launched a number of mining machine chips, once competing with mining machine manufacturers such as bitland, Jianan technology and Yibang international. It was only after the bitcoin miner market cooled that the company began to turn to other IP and custom chip development. As a one-stop leader in chip IP and chip customization in China, SMIC provides the world’s mainstream generation factories (TSMC / Samsung / lattice core / SMIC international / Lianhua Electronics / Intel / Shanghai Huali / Wuhan Xinxin, etc.), a complete set of high-speed hybrid circuit IP core and ASIC customization solutions from 180nm to 5nm process, especially the FinFET process below 22nm Up to now, it is the only technology provider in China that has the capability of 5nm process library and design flow sheet for two generation factories (TSMC and Samsung) < / P > < p > “all IP and products are self-contained and controllable, supporting the mass production of billions of chips by well-known enterprises at home and abroad, such as Huawei Hisense, ZTE, Ruixin micro, Junzheng, AMD, Microsoft, Amazon, microchip, cypress, micro, Synaptics, Google, ONSEMI and other well-known enterprises at home and abroad, and China’s market share has been far ahead for 10 consecutive years.” Core technology in self introduction said. < / P > < p > according to the company, SMIC and Changdian technology signed the contract for entrusted chip packaging design and processing in March 2018, and the latter provided chip packaging services to it. Due to the unqualified packaging quality, the chip could not work normally, resulting in the loss of incoming material cost of 14.151 million US dollars, and the chip and wafer inventory temporarily detained by Changdian technology lost US $12.864 million The total is $25 million. < / P > < p > Changdian technology disclosed in the announcement that the core technology company (overseas company of core technology) registered in Samoa has entrusted Xingke Jinpeng, a holding subsidiary of Changdian technology, to provide chip packaging services for its bitcoin miner chip since August 2017. By the end of March 2018, Xindong should pay about $8 million for packaging and testing services of Xingke Jinpeng, and until June 2018, it should pay service fees To $13.25 million. Coincidentally, on the day when Zhuhai Special Zone news released the success news of SMIC’s N + 1 process, ZTE vice president Li Hui disclosed that the 7Nm chip developed by ZTE had been put into commercial use on the main control chips of 5g wireless base stations and switches. < / P > < p > it is worth mentioning that in mid-2018, when commenting on ZTE, China Merchants Securities said: “the self-sufficiency rate of base station chip is almost zero, which is the most thorny problem of ZTE in the embargo incident.” The report shows that the number of app store purchases soared in the first half of this year due to the impact of covid-19
