Patent ID: 7968980

Claim:
A semiconductor device comprising: a support member having an insulating substrate and a pair of first conductive materials disposed on the insulating substrate, one of said first conductive materials being disposed adjacent a first end portion of said insulating substrate and another of said first conductive materials being disposed adjacent a second end portion opposite to said first end portion, and said support member also having a pair of second conductive materials on the insulating substrate, one of said second conductive materials being disposed adjacent a third end portion of said insulating substrate and another of said second conductive materials being disposed adjacent a fourth end portion opposite to said third end portion, said third and fourth end portions being longer than said first and second end portions; and a sealing member covering a semiconductor element arranged on said support member; wherein said support member has an insulating portion where the insulating substrate is exposed between the pair of the first conductive materials, and at least one of the pair of the second conductive materials is arranged adjacent to a side of the insulating portion, and said sealing member is disposed so that said sealing member covers at least a part of at least one of the first conductive materials and the second conductive materials.
