Abstract:
In a method of manufacturing a semiconductor device, an underlying structure is formed. A surface grafting layer is formed on the underlying structure. A photo resist layer is formed on the surface grafting layer. The surface grafting layer includes a coating material including a backbone polymer, a surface grafting unit coupled to the backbone polymer and an adhesion unit coupled to the backbone polymer.

Claim (Index 29):
A method of manufacturing a semiconductor device, the method comprising:\n forming an underlying structure; forming a first dielectric layer over the underlying structure; forming a silicon nitride layer on the first dielectric layer; forming a second dielectric layer on the silicon nitride layer; forming a first hard mask layer on the second dielectric layer; forming a bottom layer on the hard mask layer; forming a middle layer on the bottom layer; forming a surface grafting layer on the middle layer; forming a photo resist layer on the surface grafting layer; patterning the photo resist layer, thereby forming a resist pattern; and etching the surface grafting layer and the middle layer by using the resist pattern as an etching mask, wherein the surface grafting layer includes a coating material comprising:\n a backbone polymer; \n a surface grafting unit coupled to an end of the backbone polymer; and \n an adhesion unit different from the surface grafting unit and coupled to the backbone polymer as a side chain.
