Abstract:
1. A method of manufacturing a semiconductor article comprising the steps of: preparing a first structure comprising a first semiconductor substrate, a compound semiconductor multilayer film, and an etching sacrificial layer provided between the first semiconductor substrate and the compound semiconductor multilayer film; preparing a second structure comprising a second semiconductor substrate and an insulating layer; bonding the first structure and the second structure; forming a second groove intermittently in the second semiconductor substrate; forming a third groove in the insulating layer through the second groove; forming a first groove in the compound semiconductor multilayer film through the second and third grooves so as to expose the etching sacrificial layer; and etching the etching sacrificial layer through the first, second, and third grooves so as to separate the first semiconductor substrate and transfer the compound semiconductor multilayer film to the second semiconductor substrate from the first semiconductor substrate.
