发明名称 Semiconductor device fabrication method and semiconductor device
摘要 In fabricating a semiconductor device, an element forming surface formation step of forming a plurality of element forming surfaces of different heights on a semiconductor layer to have different levels, a semiconductor element formation step of forming a plurality of semiconductor elements and, one in each of a corresponding number of regions of the semiconductor layer, each region including an associated one of the plurality of element forming surfaces, a level-difference compensation insulating film formation step of forming a level-difference compensation insulating film on the semiconductor layer to cover the semiconductor elements and have a surface with different levels along the element forming surfaces, a release layer formation step of forming a release layer in the semiconductor layer by ion-implanting a peeling material through the level-difference compensation insulating film into the semiconductor layer, and a separation step of separating part of the semiconductor layer along the release layer are performed.
