Abstract: The method for manufacturing a semiconductor substrate comprises (a) depositing a silicon layer (32), an insulating film (39)and a polycrystalline silicon layer (36) on a monocrystalline silicon substrate (31), and polishing the surface of the layer (36), (b)bonding the layer (36) to a monocrystalline silicon substrate (37), heat-treating them, and polishing the substrate (31)to form a monocrystalline silicon layer (31a), and (c) selectively wet-etching the layer (31a) to retain the substrate (37)and the layer (32). The method is used in the mfr. of the silicon on insulator (SOI) substrate.
