Title: Base substrate for bonding and its manufacturing method
Inventor: KOMATSU KEI
IPC: H01L27/12
Filed: 1996-07-02
Abstract: PROBLEM TO BE SOLVED: To provide a base substrate for bonding which does not require any large quantity of polishing, a method for manufacturing the same, and an inexpensive base substrate which is free from Fe contamination and a method for manufacturing the same. SOLUTION: The etched surface of a wafer is polished by 3μm until the total thickness variation(TTV) of the polished surface becomes 0.35μm with a #4000 vitrified grinding wheel on which abrasive grains are solidified together by using a porcelain bonding material. Then, the polished surface is ground by 7μm by mirror polishing until the TTV becomes 0.40μm. Thus, the surface of the etched wafer is removed by 10μm in total. Alternatively, after the vitrified grinding wheel (#4000) and resinoid grinding wheel (#2000) are respectively mounted on the shafts of a two-shaft grinding machine, the etched surface of the wafer is polished by 3μm with the vitrified grinding wheel and 2-5μm with the resinoid grinding wheel.  In addition, the polished surface is ground by 5μm by mirror polishing so as to obtain a base substrate for bonding SOI having high flatness (of about 0.40μm in TTV). Therefore, the polishing and grinding amounts of the etched surface of the wafer become smaller and a substrate which is free from Fe contamination can be manufactured inexpensively.
