The hottest picture to understand 300mm wafer fact

  • Detail

A picture shows how many years 300mm wafer factories will lead the foundry capacity.

with the increasingly bleak prospect of 450mm wafer, it is expected that at least 25 new 300mm wafer factories will be launched in the world from 2016 to 2021

due to the dim development prospect of 450mm wafers, IC manufacturers are trying to increase the production capacity of 300mm and 200mm wafers. According to the prediction of the "2017-2021 global wafer production capacity report" published by IC insights, from this year to 2021, the number of 300mm wafer plants with mass production level in the world will increase every year. By 2021, the number of 300mm wafer plants will reach 123, and this number will be 98 in 2016 when the handwheel on the beam is turned by 2

as shown in Figure 1, by the end of 2016, 300mm wafers had contributed 63.6% of the global IC Fab capacity, which is expected to reach 71.2% by the end of 2021. In these five years, the annual compound average growth rate (CAGR) calculated by silicon wafer area will reach 8.1%

as of the end of 2016, 98 300mm Fabs with mass production level in the world were counted in the report, excluding many production lines used in the R & D stage and some 300mm Fabs with large capacity used to manufacture non IC semiconductors (such as power transistors). This year, eight 300mm wafer factories have been established, and Toray will enhance its PPS material production capacity and start or will soon start operations. According to this global wafer production capacity report, This is a new one opened in one year since 2014 ".300mm wafer factory is the highest number. In 2014, a total of 7 new 300mm wafer factories were opened in the world. Not only that, the report also predicts that 9 300mm wafer factories will be put into operation in 2018. Basically, all new wafer factories will be used to produce DRAM and flash memory in urgent need at present, or to strengthen the existing OEM capacity.

300mm wafer is the main demand in use now, both in terms of the overall surface area and the actual wafer shipment To also take 5 mm or 20 mm force wafer size. Nevertheless, 200mm wafer factory still has a long vitality. From now on to 2021, the IC production capacity of 200mm wafers is expected to continue to grow. Based on the total area of available silicon wafers, the average annual compound growth rate is expected to be 1.1%. However, the share of 200mm wafer in global wafer capacity is expected to decline from 28.4% in 2016 to 22.8% in 2021

ic insights believes that the reason why 200mm wafer factories still have long vitality is that not all semiconductor devices can take advantage of the cost savings that 300mm wafers can provide. 200mm wafer factory can continue to operate for many years and remain profitable. It can be used to manufacture various types of IC, such as dedicated memory, display drivers, microcontrollers, RF devices and analog products. In addition, 200mm wafer factories can also be used to manufacture "non IC" products based on MEMS, such as accelerometers, pressure sensors and actuators, as well as acoustic RF filtering devices and micro mirror chips for digital projectors and displays, as well as discrete power semiconductors and some high brightness LEDs
