METHOD FOR PRODUCING SEMICONDUCTOR DEVICE

摘要

Provided is a semiconductor device manufacturing method, comprising forming a first sacrificial layer that contacts at least a portion of a first semiconductor layer and has a higher solid solubility for impurities included in the first semiconductor layer than the first semiconductor layer; annealing the first sacrificial layer and the first semiconductor layer; removing the first sacrificial layer through a wet process; after removing the first sacrificial layer, performing at least one of forming an insulating layer that covers at least a portion of the first semiconductor layer and etching a portion of the first semiconductor layer; and forming an electrode layer that is electrically connected to the first semiconductor layer.
