Patent ID: 7999364

Claim:
A lead frame structure, providing both mechanical support and means for electrical communication between at least one semiconductor die and external circuitry, comprising: at least two electrical leads, each of said electrical leads having a plurality of finger shaped structures extended unilaterally outward therefrom, wherein said at least two electrical leads are arranged so that, from a top plan view, said plurality of finger shaped structures forms inter-digital patterns where said at least one semiconductor die is attached to said lead frame structure, wherein said at least two electrical leads comprise a first electrical lead, a second electrical lead, and a third electrical lead, wherein said plurality of finger shaped structures further comprises a first plurality of finger shaped structures, a second plurality of finger shaped structures, a third plurality of finger shaped structures, and a fourth plurality of finger shaped structures and wherein: said first electrical lead including said first plurality of finger shaped structures extending unilaterally outward therefrom; said second electrical lead coupling to said second plurality of finger shaped structures and said third plurality of finger shaped structures, said second plurality of finger shaped structures extended unilaterally outward from one side of said second electrical lead, said third plurality of finger shaped structures extended unilaterally outward from the opposite side of said second electrical lead; and said third electrical lead coupling to said fourth plurality of finger shaped structures extending unilaterally outward therefrom, said second electrical lead, and said third electrical lead are juxtaposed next to one another so that said first plurality of finger shaped structures and said second plurality of finger shaped structures form a first inter-digital pattern where a first semiconductor die is bonded to said lead frame structure, and so that said third plurality of finger shaped structures and said fourth plurality of finger shaped structures form a second inter-digital pattern where a second semiconductor is bonded to said lead frame structure.
