At present, there are two shareholders: Chengdu Jiji Semiconductor Co., Ltd. has invested 3.065 billion yuan, holding 60% of the shares; Zhenxin (Beijing) Semiconductor Co., Ltd. has invested 2.04364 billion yuan, holding 40% of the shares.
At present, the number of core technicians of true core semiconductor has reached 230. In addition to Cui Zhenju, there are two senior generals, skhan and yhkhoh, serving as coo and CTO respectively.
According to the sources in the industry, gaozhen technology, a joint venture between Zhenxin semiconductor and Chengdu government, will take over the factory building invested by Chengdu municipal government for grid core Chengdu plant, which will build DRAM production line on this basis.
Whats Cui Zhenju, vice president of SK hailis?
In addition, according to people familiar with the matter, Cui has been in China for many years.
In an interview with domestic media in 2018, he said, the Korean semiconductor industry has felt the progress of China. Although South Koreas enterprises are larger and their comprehensive technical strength is stronger, Chinas pace is obviously faster.
In 2019, Cui Zhenji established Zhenxin (Beijing) Semiconductor Co., Ltd. in China. According to the companys data, Zhenxin has applied for 43 patents related to wafer manufacturing. All technologies are developed in cooperation with microelectronics of the Chinese Academy of Sciences. Two of the patents are directly related to DRAM chips.
At present, in the rumor that there will be a new supplier, the industry is waiting to see whether Chengdu grid core can really usher in a new life.
How did Chengdu Gexin decline when the 10 billion project was completed?
Before Wuhan Hongxin, which plans to invest 100 billion yuan, disclosed itself or will be ruined, Chengdu Gexin was once regarded as the largest factory corpse in the industry.
Global foundries, headquartered in California, is now the worlds third largest semiconductor foundry, second only to TSMC and Samsung Electronics.
Lattice chip used to belong to AMD (SUPERWAY semiconductor), and then became independent when amd spun off its chip manufacturing business in 2009. It was acquired by Mubadala Investment Co, a sovereign fund of Abu Dhabi government, as its subsidiary.
Over the past decade, mubada has invested more than US $21 billion in the establishment and expansion of semiconductor production lines in Europe and the United States, resulting in further expansion of lattice core capacity.
As a wafer manufacturer that can compete with TSMC and Samsung, Gexin will not miss this big cake of China.
At that time, the main chip manufacturing factories in the world, TSMC, grid core and united power, all came to the Chinese mainland to seek cooperation. When Nanjing has TSMC and Xiamen has liandian, Chengdu, as a new first tier city in Central China, is not willing to fall behind.
In May 2017, lattice core announced the construction of a 12 inch wafer plant in Chengdu, with an estimated investment of more than US $10 billion, making it the first 12 inch wafer production line in the southwest of the mainland.
The total investment scale of grid core in Chengdu has exceeded 10 billion US dollars. The Chengdu government has invested 7 billion yuan for the construction of grid core plant, which is responsible for the construction of plant and supporting facilities, as well as the establishment of R & D, operation and logistics teams.
In October 2018, Gexin announced that it had signed an amendment with Chengdu, canceling its contribution to the phase I project.
However, the closure of Chengdu Gexin factory is closely related to its parent company.
In addition, different from the FinFET process used by most wafer manufacturing companies, the fd-soi process is selected for the grid core. However, the development of fd-soi process is limited by the imperfect ecosystem, and the IP construction, mass production experience and application promotion are not satisfactory. The research and development of chip technology needs first-class technology and second, strong financial support.
It is worth noting that similar unfinished plots are not new in China. Wuhan Hongxin, Nanjing dekema and Dehui semiconductor have become cannon fodder.
Ren Zhengfei, President of Huawei, also said this:
Making chips is not a matter of pinching mud balls. It cant be done overnight. This process involves various fields of technology, as well as some raw materials, all of which take time to acquire. At present, some people are exaggerating the research and development of chips in order to get some money in the secondary market.
