Method for forming semiconductor structure
A method for forming a semiconductor device structure is provided. The method includes forming a material layer over a substrate and forming a resist layer over the material layer. The method includes exposing a portion of the resist layer by performing an exposure process. The resist layer includes a compound, and the compound has a carbon backbone, and a photoacid generator (PAG) group and/or a quencher group are bonded to the carbon backbone. The method also includes performing a baking process on the resist layer and etching a portion of the resist layer to form a patterned resist layer. The method includes patterning the material layer by using the patterned resist layer as a mask and removing the patterned resist layer.
