Title: Substrate for epitaxial treatment, epitaxial wafer, semiconductor device, and epitaxial growth method
Inventor: UEDA TETSUZO
IPC: C30B25/18
Filed: 2002-07-11
Abstract: PROBLEM TO BE SOLVED: To provide a wafer which remains flat after III-V nitride growth on a substrate and which is suitable for subsequent high-yield processing of a high performance device. SOLUTION: A substrate comprising at least two layers which have different thermal expansion coefficients (TECs) is used for subsequent epitaxial growth of a semiconductor. A typical example is an epitaxial growth of III-V nitride (InGaAlBNAsP alloy semiconductor) on sapphire 210. Due to the thermal mismatch between a III-V nitride epitaxial layer 214 and the sapphire 210, an epitaxially-processed wafer bows in a convex manner during cool down after growth. The layered substrate compensates for the thermal mismatch between the epitaxial layer 214 and the top layer 210 of the substrate, resulting in a flat wafer suitable for subsequent processing at a high yield.
