Title: Gallium nitride semiconductor device and method of manufacturing gallium nitride semiconductor device
Inventor: YOSHIDA KIYOTERU
IPC: H01L29/20
Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To obtain an amorphous state buffer layer free from surface uneven ness, by forming a GaN single crystal buffer layer whose film thickness is specified, on the surface of a substrate. SOLUTION: Since a natural oxide film sticks on a substrate, the film is eliminated by increasing the substrate temperature. After the substrate temperature is set at, e.g. 700 deg.C and then stabilized, irradiation with Ga and dimethyl hydrazine is started. When the surface is observed by using a high speed electron beam diffraction equipment (RHEED), spots of GaN are appearing between spot rows showing a sapphire substrate. The growth of GaN is stopped when the RHEED spots do not vanish, e.g. after 5 minutes. The RHEED pattern shows that the GaN surface is flat in the atomic order and GaN is composed of single crystal. By Auger measurement and a transmission electron microscope, it can be confirmed that the film thickness of GaN is at most 3nm, e.g. equivalent to 2nm.
