Abstract:
A method for producing a semiconductor device comprising:a first step of forming a first electrically insulating layer on a wafer containing a circuit electrode, said first electrically insulating layer covering a periphery portion of said circuit electrode; a second step of forming a second electrically insulating layer, having an inclined portion and a flat portion, on said first electrically insulating layer, said second electrically insulating layer having a function to relax a stress between said semiconductor device and a circuit board on which said semiconductor device is to be mounted, wherein said second electrically insulating layer is formed by printing an electrically insulating material including particles on said first electrically insulating layer with a mask; a third step of forming a wiring on said inclined portion and said flat portion of said second electrically insulating layer, a portion of said wiring on said inclined portion being electrically connected to a portion of said wiring on said flat portion; and a fourth step of forming an external connection terminal on said second electrically insulating layer, said external connection terminal being electrically connected with said circuit electrode through said wiring.
