Patent ID: 7238232

Claim:
A process of synthesizing a textured thin film of gallium nitride on a substrate comprising the steps of: using a dissolution of atomic nitrogen rather than molecular nitrogen to allow for growth at subatmospheric pressure; preparing a substrate sheet selected from the group consisting of a single crystalline substrate, a polycrystalline substrate and an amorphous substrate by: a) cleaning the sheet with a hydrogen fluoride (HF) solution; b) ultra sonicating said sheet in acetone; c) covering with a thin liquid gallium film; d) heating said gallium film on said sheet to a temperature of 800 –1,000 degrees C.; e) exposing said sheet to a nitrogen plasma environment, dissolving nitrogen in the liquid gallium; and f) precipitating out of the solution gallium nitride crystals whereby said gallium nitride crystals self-orient with one another to form a uniform texture.
