Patent ID: 8551828

Claim:
A method of manufacturing a semiconductor device: preparing a base substrate and a semiconductor substrate; irradiating the semiconductor substrate with ions, whereby a damaged region is formed in the semiconductor substrate; forming a bonding layer over at least one of the base substrate and the semiconductor substrate; attaching the base substrate and the semiconductor substrate to each other with the bonding layer interposed therebetween; heating the semiconductor substrate and the base substrate by a heating apparatus at a first temperature; and heating the semiconductor substrate and the base substrate by a rapid thermal annealing apparatus at a second temperature, so that a semiconductor layer separated at the damaged region of the semiconductor substrate is formed over the base substrate with the bonding layer therebetween, wherein the ions include H + ions, H 2 + ions, and H 3 + ions, and wherein the H 3 + ions occupy 70% or more of the total amount of the H + ions, the H 2 ± ions, and the H 3 + ions.
