Abstract
Abstract A semiconductor device comprises a square-shaped first semiconductor chip having a first LSI, a square-shaped second semiconductor chip having a second LSI, which is smaller in size than the first semiconductor chip and connected to the first semiconductor chip by face down bonding, and a square-shaped package made of a molding resin for packaging the first and second semiconductor chips. The respective centers of the first and second semiconductor chips are offset from each other, while the center of the second semiconductor chip is substantially coincident with the center of the molding resin.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
127 words
A semiconductor device comprising: a first semiconductor chip having a first LSI; a second semiconductor chip having a second LSI, said second semiconductor chip being smaller in size than said first semiconductor chip and connected to said first semiconductor chip by face down bonding; and a package for packaging said first and second semiconductor chips, wherein the center of said first semiconductor chip is offset from the center of said second semiconductor chip in a first direction in which a first one of two contiguous edges of said second semiconductor chip extends, said first edge being as long as or shorter than the other one of the two contiguous edges, while the center of said second semiconductor chip is substantially coincident with the center of said package.
Claim 2
Dependent Claim
127 words
A semiconductor device comprising: a first semiconductor chip having a first LSI; a second semiconductor chip having a second LSI, said second semiconductor chip being smaller in size than said first semiconductor chip and connected to said first semiconductor chip by face down bonding; and a package for packaging said first and second semiconductor chips, wherein the center of said first semiconductor chip is offset from the center of said second semiconductor chip in a first direction in which a first one of two contiguous edges of said second semiconductor chip extends, said first edge being as long as or shorter than the other one of the two contiguous edges, while the center of said second semiconductor chip is substantially coincident with the center of said package.
Claim 3
Dependent Claim
71 words
A semiconductor device according to claim 1, wherein the center of said first semiconductor chip is offset from the center of said second semiconductor chip in a second direction in which a second one of the two contiguous edges of said second semiconductor chip extends, said second edge being different from said first edge, while the center of said second semiconductor chip is substantially coincident with the center of said package.
