Abstract:
A method for manufacturing a semiconductor device includes: forming a multilayered epitaxial structure on a substrate; applying a novolac-based resist on the multilayered epitaxial structure and patterning the resist through transfer; tapering a shape of the patterned resist by baking; dry-etching the multilayered epitaxial structure using the tapered resist as a mask; and after the dry etching, removing the resist and forming a coating film on the multilayered epitaxial structure, wherein an etching selection ratio between the resist and the multilayered epitaxial structure in the dry etching is controlled to 0.8 to 1.2 so that an inclination is formed in the multilayered epitaxial structure.

Claim (Index 6):
The method for manufacturing a semiconductor device according to  claim 2 , wherein the multilayered epitaxial structure is a GaN-HEMT structure, and\n a depth of the dry etching is greater than a depth of the 2DEG part which is an operation layer of the GaN-HEMT structure.
