Abstract

Abstract Translated from Japanese (57)【要約】 【課題】 GaN基板上に成長させるデバイス構造に微 細なクラックが発生することを防止し、寿命特性などの 素子特性を向上させ、信頼性の更なる向上が可能な窒化 物半導体素子を提供することである。 【解決手段】 GaN基板上に、GaNより熱膨張係数 の小さい窒化物半導体[Al a Ga 1-a N(0<a< 1)]を成長させ、その上にデバイス構造を形成させて なる。 PROBLEM TO BE SOLVED: To provide a nitride capable of preventing generation of minute cracks in a device structure grown on a GaN substrate, improving element characteristics such as life characteristics, and further improving reliability. It is to provide a semiconductor device. SOLUTION: On a GaN substrate, a nitride semiconductor [Al a Ga 1-a N (0 <a < 1)], and a device structure is formed thereon.
