Abstract:
1. A method for manufacturing a partial SOI substrate, the method comprising: a step of forming a first substrate which has a semiconductor region, a partial insulating layer and a semiconductor layer, the semiconductor region including first and second regions, the partial insulating layer being arranged on the first region so as to be in contact with the first region, and the semiconductor layer being arranged on the second region and the partial insulating layer; a step of implanting ions into the first substrate through a surface of the first substrate to form a separation layer at a position deeper than a position of the partial insulating layer; a step of bonding a second substrate to the surface of the first substrate, in which the separation layer is formed, to form a bonded substrate stack; and a step of splitting the bonded substrate stack at the separation layer to form a partial SOI substrate including an SOI layer comprising the first region arranged on the partial insulating layer so as to be in contact with the partial insulating layer.
