次に、本発明の実施形態に係る半導体装置の製造方法の具体例を、以下に図面を参照しつつ説明する。本明細書中においては、個別面を()、集合面を{}でそれぞれ示す。また、負の指数については、結晶学上、”−”(バー)を数字の上に付けることになっているが、本明細書中では、数字の前に負の符号を付けている。
まず、本発明の一態様である実施形態1に係る半導体装置の製造方法について説明する。図1を参照して、まず工程(S10)として半導体基板準備工程が実施される。この工程(S10)では、図2を参照して、たとえばポリタイプが4H型である炭化珪素(SiC)インゴット(図示しない)を所定厚みにスライスすることにより、SiC基板10(半導体基板)が得られる。SiC基板10は、(0001)面(シリコン面)である主面10a(第1主面)と、当該主面10aと反対側の(000−1)面(カーボン面)である主面10b(第2主面)とを有している。
次に、本発明の他の態様である実施形態2に係る半導体装置の製造方法について説明する。本実施形態に係る半導体装置の製造方法は、基本的には上記実施形態1に係る半導体装置の製造方法と同様の工程により実施され、かつ同様の効果を奏する。しかし、本実施形態に係る半導体装置の製造方法は、工程(S20)におけるSiC基板10の固定方式において上記実施形態1とは異なっている。
