BERLIN/FRANKFURT, Feb 1 (Reuters) - U.S. chipmaker Wolfspeed (WOLF.N) will build a $3-billion chip plant and a research and development centre in Germany, it said on Wednesday, expecting to start construction within months provided it receives subsidy approval from the European Union. Automotive supplier ZF (ZFF.UL) will invest $185 million for a stake in the chip fab and will take a majority stake in the research centre, the companies said. Wolfspeed expects to receive 20% of the investment amount in subsidies, Chief Executive Gregg Lowe told German newspaper Handelsblatt. Volkswagen, Europe's top carmaker, earlier this month warned that the chip squeeze meant 2023 would remain volatile and challenging, but expected supplies to improve. The company announced in September a new plant in the United States due for completion in 2030.
