Abstract:
A semiconductor device comprising:a semiconductor chip having a main surface, said semiconductor chip including an integrated circuit and external terminals formed in said main surface, said main surface having a first pair of edges and a second pair of edges, said first pair of edges extending in a first direction, said second pair of edges extending in a second direction different than said first direction;a first signal lead and a second signal lead, each having an inner lead and an outer lead which is continuous with said inner lead, said inner lead having a first portion and a second portion, each of the first portions being disposed over said main surface of the semiconductor chip and being spaced from each other in said first direction, each of the second portions of the inner leads of each of said first and second signal leads crossing one of said first pair of edges and extending out of said semiconductor chip;an insulating adhesive film being disposed between said main surface of said semiconductor chip and said first portions of said inner leads of said first and second signal leads;bonding wires electrically connecting said external terminals of said semiconductor chip with said first portions of said inner leads of said first and second signal leads; anda sealing member sealing said semiconductor chip, said bonding wires, and said inner leads of said first and second signal leads, said outer leads of said first and second signal leads extending outwardly from said sealing member,wherein said main surface of said semiconductor chip and each of said first portions of said inner leads of said first and second signal leads are adhered to each other by said insulating adhesive film,wherein said insulating adhesive film has a first part disposed under said first portion of said inner lead of said first signal lead, a second part disposed under said first portion of said inner lead of said second signal lead, and a third part between said first and second parts, andwherein a width of said third part of said insulating adhesive film, extending in the second direction, is narrower than that of each of said first and second parts of said insulating adhesive film in said second direction.
