Bosch to enter production of SiC power semiconductors
The automotive supplier Bosch plans to use more efficient power semiconductors to extend the range of electric vehicles.

The company is the only automotive supplier that also manufactures semiconductors. In addition to the power components, these are mainly MEMS sensors and ASICs. At its second production site in Dresden, which is scheduled to start operations in spring 2020, Bosch will manufacture on 300-mm wafers. Already this year, the first 200 employees will start their work in the new wafer factory in the immediate vicinity of Globalfoundries. The fabs in Reutlingen and Dresden will complement each other ideally, Kröger said.

Bosch currently estimates the average value of semiconductor products (power electronic components, sensors, and integrated circuits) used in vehicles at around 370 US dollars. This figure is growing at an annual rate of 1 to 2 %. The electrification of the powertrain will give a significant boost to the semiconductor content of cars: it will also bring on board semiconductors worth an average of 450 dollars. Experts assume that the automation of driving will increase this value by a further 1000 dollars.
