Title: Sapphire substrate for semiconductor device
Inventor: KIMURA MINORU
IPC: H01L21/304
Filed: 1981-11-25
Abstract: PURPOSE:To make easy preparation of chips and prevent generation of crack by providing a cut-away portion matching the crossing direction of the sapphire single crystal surface and cleavage surface. CONSTITUTION:A sapphire substrate of plane orientation of (-1012) has a cleavage surface of (-1012). It also has two zone axes orthogonally crossing each other, the crossing lines [2-201] and [02-21] of the cleavage surface and plane orientation. When a cut-away surface 2 matching the zone axis [2-201] is formed at the surface 1, the other zone axis [02-21] orthogonally crosses the cut-away surface. The dicing at the time of cutting a chip can easily be done only with shallower cutting than that of conventional one. Therefore, the life of diamond stylus can be expanded several times and a minute crack at the right angle to the scribe direction can be reduced. This cut-away 2 in the SOS structure does not give any influence on the element characteristic substantially formed since an error to the crystal axis of the Si epitaxial layer is about 2-3 deg.. According to this structure, a sapphire substrate which ensures easy scribe and high reliability of dicing can be obtained.
