发明名称 SEMICONDUCTOR DEVICE AND METHOD FOR FABRICATING SEMICONDUCTOR DEVICE
摘要 A semiconductor device includes: a semiconductor substrate; a wiring layer provided on a front-surface side of the semiconductor substrate; a through-via that penetrates through the semiconductor substrate from a back-surface side of the semiconductor substrate and is coupled to a wire included in the wiring layer; and a stress relaxation part that protrudes toward a through-via side and is disposed on a section in the wire and coupled to the through-via, the stress relaxation part including at least one insulating portion containing an insulating material having a smaller thermal expansion coefficient than a material of the through-via.
