摘要： A first solder resist section and a second solder resist section are formed over an upper surface of a wiring board. A semiconductor chip is bonded onto the first solder resist section via an adhesive interposed therebetween. Electrodes of the semiconductor chip are respectively electrically connected to connecting terminals exposed through openings of the second solder resist section via bonding wires. An encapsulating resin is formed over the upper surface of the wiring board so as to cover the semiconductor chip and the bonding wires. A plane dimension of the first solder resist section is smaller than that of the semiconductor chip, and the encapsulating resin is filled even below an outer peripheral portion of a back surface of the semiconductor chip.

摘要： There are constituted by a tab on which a semiconductor chip is mounted, a sealing portion formed by resin-sealing the semiconductor chip, a plurality of leads each having a mounted surface exposed to a peripheral portion of a rear surface of the sealing portion and a sealing-portion forming surface disposed on an opposite side thereto, and a wire for connecting a pad of the semiconductor chip and a lead, wherein the length between inner ends of the sealing-portion forming surfaces of the leads disposed so as to oppose to each other is formed to be larger than the length between inner ends of the mounted surfaces. Thereby, a chip mounting region surrounded by the inner end of the sealing-portion forming surface of each lead can be expanded and the size of the mountable chip is increased.
