The investment, for which Bosch will seek European Union funding under the Important Projects of Common European Interests (IPCEI) framework, should boost Europe's production capacity for chips in a global market still dominated by the U.S. and Asian players.

"Europe can and must capitalize on its own strengths in the semiconductor industry," said Chief Executive Stefan Hartung. "The goal must be to produce chips for the specific needs of European industry."
Bosch last year opened a 1 billion euro chip factory in Dresden, a record investment as it sought to stake its claim in the growing market for chips to equip self-driving and electric cars amid a global shortage.
A total of 170 million euros will go into the new development centres in Reutlingen and Dresden, with 250 million euros to be spent on expanding the existing Dresden site.
How the remaining funds will be spent is yet to be decided, Hartung said.
The CEO expects bottlenecks in chip supply, from strained shipping networks to low production capacity, to continue for several more months, even as inflation eases pressure on some parts of the sector by reducing demand for expensive consumer goods.
Bosch's chips need to be shipped from Germany to Malaysia and back again in the production process, meaning any disturbance to shipping could add weeks to delivery times, Hartung said.
"There are areas where certainly demand will fall such that you can order substantive sums at any time.... there are however also areas where not as much capacity was added and demand is still very high," he said.
