Abstract:
A method of manufacturing a semiconductor device includes stacking a first substrate comprising a first surface having a semiconductor element and an opposing second surface and a second substrate comprising a third surface having a semiconductor element and an opposing fourth surface, forming a first contact hole extending from the second surface to the first surface of the first substrate and forming a first groove inwardly of a first region of the second surface of the first substrate by etching inwardly of the first substrate from the second surface thereof, forming a first patterned mask on the first substrate, so that the first groove is covered by the material of the first patterned mask, forming a first metal electrode in the first contact hole through an opening in the first mask as a mask, and removing the first mask and subsequently cutting through the first substrate in the first groove.

Claim (Index 8):
A semiconductor device comprising:\n a first semiconductor substrate comprising a first surface having a semiconductor element layer thereon and a second surface opposite to the first surface; a second semiconductor substrate comprising a third surface having a semiconductor element layer thereon and a fourth surface opposite to the third surface, wherein the second semiconductor substrate is stacked on the first semiconductor substrate with the third surface facing the first surface; a metal electrode extending at least one of between the first surface and the second surface of the first semiconductor substrate and between the third surface and the fourth surface of the second semiconductor substrate; and an insulating film extending along a side surface of the second semiconductor substrate.
