Patent ID: 8574962

Claim:
A method of manufacturing a semiconductor device, comprising the steps of: (a) applying a resin member directly onto a first main surface of a semiconductor wafer having an uneven structure on said first main surface thereof; (b) flattening a surface of said resin member by heating said resin member; (c) performing a thinning process for said semiconductor wafer on a second main surface thereof after said step (b); (d) removing said resin member from said semiconductor wafer after said step (c); (e) between said step (b) and said step (c), attaching a surface protection tape directly onto said surface of said resin member which is flattened; (f) removing said surface protection tape from said resin member between said step (c) and said step (d); further comprising the steps of: (g) forming a diffusion layer on said second main surface of said semiconductor wafer between said step (c) and said step (d); (h) forming an electrode on said second main surface of said semiconductor wafer between said step (g) and said step (d); and further comprising the steps of: (i) mounting said second main surface of said semiconductor wafer onto a dicing tape between said step (h) and said step (d); and (i) performing dicing on said semiconductor wafer to dice said semiconductor wafer into individual chips between said step (i) and said step (d).
