Title: Method of manufacturing compound semiconductor device
Inventor: ASANO TETSURO
IPC: H01L29/04
Filed: 2002-07-08
Abstract: PURPOSE: To solve a problem that the yield of a semiconductor device is lowered or work efficiency is not improved because of working at a decelerated dicing speed since chipping frequently occurs in the case of cutting conventionally when the orientation flat of a wafer is formed in the direction of '01 bar 1 bar' and dicing is performed vertically and horizontally with the orientation flat. CONSTITUTION: By forming a pattern on the wafer, with which the orientation flat is formed therewith in any one direction among '01 bar 0', '001 bar', '001' and '010', respective chips are arrayed to cross the direction of '01 bar 1 bar' at 45° and dicing is enabled. Since chipping is remarkably reduced, a chip size can be shrunk, the wafer yield can be improved and work efficiency can be improved.
