A method for fabricating a Group III nitride semiconductor substrate according to the present invention includes the steps of: (a) preparing a substrate; (b) forming, on the substrate, a first semiconductor layer composed of a Group III nitride semiconductor; (c) forming, on the first semiconductor layer, a heat diffusion suppressing layer lower in thermal conductivity than the first semiconductor layer; (d) forming, on the heat diffusion suppressing layer, a second semiconductor layer composed of a Group III nitride semiconductor; and (e) irradiating the first semiconductor layer through the substrate with a light beam transmitted by the substrate and absorbed by the first semiconductor layer to decompose the first semiconductor layer.
摘要:
A protector film is formed on the surface of a substrate to cover at least the side surface thereof. Then, a compound semiconductor film including nitrogen is grown through epitaxial growth on the substrate at an exposed portion. Then, the substrate and the compound semiconductor film are separated from each other by irradiation of laser light, polishing of the substrate, etching, cutting, etc. Consequently, the resulting compound semiconductor film is used as a free-standing wafer.
摘要:
An image forming apparatus has a plurality of image bearing members which are disposed along the conveying direction of transfer material and on which latent images are formed. Developing devices are disposed corresponding to the plurality of image bearing members and develop the latent images with developers. A transfer material bearing and conveying member and a transfer device to sequentially transfer the developer images developed on the plurality of image bearing members to the transfer material on the transfer material bearing and conveying member are also a part of the image forming apparatus. The apparatus also has a cleaning member which cleans the surface of the transfer material bearing and conveying member. A developer image that is not to be transferred onto the transfer material is formed only onto one image bearing member disposed downstream in the movement direction of the transfer material bearing and conveying member among the plurality of image bearing members. The developer image is transferred onto the transfer material bearing and conveying member by the transfer member and the transfer material bearing and conveying member is moved so that the transferred developer image reaches the cleaning member.
