Process for semiconductor device fabrication in which a insulating layer is formed on a semiconductor substrate

摘要

The present invention provides a method for manufacturing a semiconductor device comprising a III-V semiconductor substrate, and an insulating layer deposited on the substrate by Atomic Layer Deposition (ALD). The use of ALD to deposit the insulating layer was found to facilitate the creation of active devices that avoid Fermi layer pinning. In addition, such insulating layer may be advantageously used as a passivation layer in III-V substrate based active devices and transistors.
