Diamond film electronic devices

摘要

A pair of electrodes 3 are first formed on a substrate 1. Subsequently, an undoped diamond film 2 is selectively deposited between the above electrodes. A B-doped diamond film 4 is then selectively formed on both the insulating diamond film and pan of each electrode. The substrate may be contained in a container provided with an opening portion from which only the B-doped diamond film is exposed.
