Can BYD develop 7nm chips and 7nm mask aligner replace Foxconn?

BYD will replace Foxconn. Can BYD make a 7nm chip to buy a 7nm mask aligner? In the field of OEM, BYD is also very strong, but it can't be compared with Foxconn and can't be replaced by Foxconn. However, in the field of chip design and manufacturing, these two companies are not particularly strong at present, and there is no question of who will replace who. Comparatively speaking, BYD may be better than Foxconn in chip design and manufacturing.

BYD and Foxconn are involved in a wide range of business, both of which are involved in chip design and manufacturing. Comparatively speaking, BYD set foot in chips deeper and earlier. Foxconn didn't lay out chips until the last year or two. 20 18 When giving a speech at Peking University, Foxconn mentioned that after the acquisition of Toshiba Semiconductor failed, it would make its own chips and set up a semiconductor division. Now it has more than 100 engineers. In addition, it also controls related chip companies, such as Tianqi Technology, an LCD driver IC manufacturer, Xunxin Technology, a system-level packaging company, Peixin Energy, a semiconductor manufacturer, and Hongjing Technology, an IC design service.

BYD is not only strong in the fields of automobiles and batteries, but also has its own place in the field of foundry and its own achievements in the field of chips. It made its own IGBT chip IGBT on insulated gate bipolar transistor, which broke the monopoly position of foreign companies such as Infineon and Toyota on this chip. IGBT is very important for electric vehicles, and directly controlling the DC/ AC conversion of the drive system is as important as the battery unit. And it has a wide range of uses, from cars to subways and high-speed trains.

BYD not only has the ability to design IGBT chips, but also has the ability to manufacture them. At present, BYD's semiconductor manufacturing plant in Ningbo can produce 50,000 pieces, and by 2020, it can reach the production capacity of 6,543,800 pieces, which can be self-sufficient. However, compared with the manufacturing technology and equipment of mobile phone chips, the requirements of IGBT chips are not so high. BYD can't achieve the current 7nm process, and neither can Foxconn. In the field of mobile phone chip manufacturing, TSMC and Samsung are the absolute bosses. They not only have advanced manufacturing equipment, but also have accumulated a large number of manufacturing process patents, which are beyond the reach of other chip manufacturers (parameter | picture).
