Abstract:
1. A method for manufacturing a semiconductor apparatus, comprising: forming a step layer having a top surface and sidewalls in a first region on a substrate; forming a first semiconductor thin film on the top surface and sidewalls of the step layer; forming a second semiconductor thin film in a second region that is separated from the first region on the substrate; removing part of the first semiconductor thin film from the top surface while leaving part of the first semiconductor thin film on the sidewalls; removing part of the second semiconductor thin film in one part of the second region while leaving part of the second semiconductor thin film in the other part of the second region; removing the step layer; forming a fin-type transistor that includes the first semiconductor thin film disposed on the sidewalls as a channel; and forming a planar transistor that includes the part of the second semiconductor thin film remaining in the other part of the second region as a channel.
