Abstract
Method for producing composite wafers with thin high-quality semiconductor films atomically attached to synthetic diamond wafers is disclosed. Synthetic diamond substrates are created by depositing synthetic diamond onto a nucleating layer deposited on bulk semiconductor wafer which has been prepared to allow separation of the thin semiconductor film from the remaining bulk semiconductor wafer. The remaining semiconductor wafer is available for reuse. The synthetic diamond substrate serves as heat spreader and a mechanical substrate.
