Abstract:
1. A method of manufacturing a semiconductor device, comprising: forming an element forming layer including a plurality of element forming regions on a front surface of a semiconductor substrate; forming a passivation layer on said element forming layer; selectively removing said passivation layer and forming a scribe line groove along a periphery of each of said element forming regions; grinding a back surface of said semiconductor substrate with said front surface of said semiconductor substrate covered with a protection tape; removing said protection tape; and cutting said semiconductor substrate along said scribe line groove, wherein said forming said scribe line groove includes forming a stopper which blocks said scribe line groove, in said scribe line groove, wherein said forming said scribe line groove includes performing a step exposure so as to form said scribe line groove on said semiconductor substrate and said stopper through a single reticle at a same time, and wherein said forming said scribe line groove includes selectively removing a predetermined depth of said element forming layer together with said passivation layer.
