Title: Semiconductor device and its manufacturing method
Inventor: FUJIMOTO HIDETOSHI
IPC: H01L21/205
Filed: 2001-07-26
Abstract: PROBLEM TO BE SOLVED: To solve the problem that the performance is deteriorated by a capacitive component through a substrate at the time of high frequency operation and the problem that the lifetime of an element is shortened due to bad heat radiation at the time of high power operation. SOLUTION: A material having high thermal conductivity, e.g. aluminum nitride or the like, is employed in a substrate for crystal growth. A single crystal film having good quality can be formed on a polycrystalline substrate by an epitaxial growth method where a buffer layer is formed by heat-treating the surface of the substrate in arsin atmosphere or a polycrystalline buffer layer is formed at a temperature low enough not to start epitaxial growth of a single crystal. Since an aluminum nitride substrate having low permittivity is employed, deterioration in the performance of the device due to a capacitive component through the substrate can be suppressed. Since aluminum nitride has high thermal conductivity, heat generated especially at the time of high output can be released through the substrate and the lifetime of the element can be prolonged.
