Latest Patents

One of Tsuchiya's latest patents is a semiconductor device featuring bumper portions that are integral with a heat sink. This device is a Quad Flat Package (QFP) designed to lower heat resistance while increasing the number of pins. The QFP includes a heat-radiating metal plate with bumpers formed at the four corners as a unitary structure. A semiconductor chip is mounted on this plate, with leads surrounding the chip's periphery. Bonding wires connect the leads to the semiconductor chip, and a sealing resin member encapsulates part of the chip, inner leads, bonding wires, and part of the heat-radiating metal plate. The tips of the bumpers are strategically positioned outside the tips of the outer leads that protrude from the sealing resin member. The method of producing this QFP involves securing the heat-radiating metal plate with bumpers and the lead frame with leads outside the sealing resin member.
