A semiconductor substrate having an SOI layer is provided. Between an SOI layer and a glass substrate, a bonding layer is provided which is formed of one layer or a plurality of layers of phosphosilicate glass, borosilicate glass, and/or borophosphosilicate glass, using organosilane as one material by a thermal CVD method at a temperature of 500° C. to 800° C.
