Patent ID: 8791513

Claim:
A semiconductor device comprising: a first substrate; a transistor over a first surface of the first substrate, the transistor comprising a channel forming region and a gate electrode with a gate insulating film interposed therebetween; an interlayer insulating film over the transistor; source and drain wirings over the interlayer insulating film, the source and drain wirings electrically connected to the transistor; a second substrate over the transistor, a first surface of the second substrate facing the first surface of the first substrate; a first sealing member between the first surface of the first substrate and the first surface of the second substrate; and a second sealing member being in contact with the first sealing member, the second sealing member being in contact with side surfaces of the first and second substrates beyond end portions of the first surfaces of the first and second substrates, wherein at least one of the source and drain wirings has a taper portion at an edge portion thereof.
