PARIS, Dec 1 (Reuters) - French semiconductor materials supplier Soitec (SOIT.PA) and chipmaker STMicroelectronics said on Thursday they were deepening their cooperation over the manufacturing of a key and fast-growing material used in the electric car industry. The material, silicon carbide (SiC), is used to make a growing number of chips that improve the power management of electric vehicles. Under the enhanced cooperation, STMicro, whose biggest clients include EV maker Tesla Inc (TSLA.O), agreed to use Soitec's SiC substrate technology, in the form of a bigger, 200 millimetre wafer which is upcoming, the two companies said in a statement. While not exclusive, the Soitec-STMicro cooperation gives STMicro a time advantage in the adoption of the technology. STMicro is aiming to sell $700 million worth of SiC chips this year and is targeting $1 billion in 2023, it has said.
