Patent ID: 7132315

Claim:
A method for fabricating a plastic-encapsulated semiconductor device, the method comprising the steps of: a) preparing a leadframe comprising an outer frame with a plurality of sides surrounding a region of the leadframe on which a semiconductor chip is to be mounted, a die pad on which the semiconductor chip is to be mounted, and a plurality of leads each having land portions and connections, the land portions each having an upper surface serving as a bonding pad to be connected with a metal wiring and a lowermost part serving as an external terminal, the connections each being devoid of its lower part so as to be thinner than the land portion and being provided between the outer frame and the land portions, between the land portions associated with each other in each lead and between the land portions and the die pad, wherein the plurality of leads include no member that functions as a suspension lead during plastic encapsulation; b) mounting the semiconductor chip on the die pad of the leadframe; c) placing the leadframe on an adhesive sheet for encapsulation; d) cutting the connections with the leadframe placed on the encapsulation sheet, thus detaching, from the outer frame, the isolated land portions and the die pad; e) connecting, through a connecting member, a portion of the semiconductor chip to the associated bonding pad; and f) carrying out plastic encapsulation with the leadframe placed on the encapsulation sheet, wherein the step c) is carried out prior to or subsequent to the step b), and the steps d), e) and f) are carried out in this order after the step c) has been carried out.
