Patent ID: 8486809

Claim:
A method for producing a semiconductor device, comprising the steps of: forming a semiconductor layer on a substrate; forming a non-silicon-containing resin layer on the semiconductor layer; forming a first pattern having a projection and a recess in the non-silicon-containing resin layer; forming a silicon-containing resin layer on the non-silicon-containing resin layer so as to cover the projection and the recess; etching the silicon-containing resin layer until a surface of the projection of the non-silicon-containing resin layer is exposed, the silicon-containing resin layer being left in the recess of the non-silicon-containing resin layer; selectively etching the non-silicon-containing resin layer through the silicon-containing resin layer left in the recess of the non-silicon-containing resin layer, the non-silicon-containing resin layer having a second pattern reverse to the first pattern; and etching the semiconductor layer through the non-silicon-containing resin layer having the second pattern, wherein the step of forming the silicon-containing resin layer includes the steps of: applying a silicon-containing resin solution with a first viscosity on a surface of the non-silicon-containing resin layer to provide the silicon-containing resin layer, the silicon-containing resin solution containing a silicon-containing resin and a volatile solvent; heating the silicon-containing resin layer to a first temperature, the silicon-containing resin layer having a second viscosity by heating to the first temperature, the second viscosity being larger than the first viscosity; and applying a rinse solution containing a volatile component to an edge portion of the silicon-containing resin layer.
