Patent ID: 6991996

Claim:
A method for manufacturing a semiconductor device, comprising the steps of: (a) forming a laminated substrate by laminating a device formation layer consisting of single crystalline semiconductor on a supporting substrate consisting of single crystalline semiconductor via an insulating layer wherein a direction of a crystallographic axis of the device formation layer is shifted from a corresponding crystallographic axis of the supporting substrate; (b) forming semiconductor devices on the device formation layer within a plurality of areas divided by scribe lines, the scribe lines being defined on the device formation layer and not on the supporting substrate, the scribe lines extending to a direction being parallel to a direction of a crystallographic axis of the supporting substrate where the supporting substrate is easy to be cleaved; and (c) splitting the laminated substrate into a plurality of chips by cleaving the supporting substrate along the scribe lines; wherein the step (b) further comprises the step of forming a wiring layer comprising wiring wherein at least 70% of a full length of all the wiring in the wiring layer extends to a direction being substantially parallel to a direction of a crystallographic axis of the supporting substrate where the supporting substrate is easy to be cleaved.
