Abstract:
1. A semiconductor package with a lead frame as a chip carrier, comprising: a lead frame having a die pad and a plurality of leads spaced apart from the die pad by a predetermined distance, each of the leads being composed of an inner lead portion and an outer lead portion integral with the inner lead portion, wherein the leads are all disposed on one side of the lead frame; at least a chip mounted on a surface of the die pad and electrically connected to the inner lead portions; a first encapsulant formed on the lead frame for encapsulating bottom portions of the chip, the die pad, and the inner lead portions and for allowing the outer lead portions to outwardly protrude from the first encapsulant; and an injection-molded second encapsulant made of a thermoplastic resin material for covering the first encapsulant and the outer lead portions protruded from the first encapsulant, allowing a surface of each of the terminals of the outer lead portions and a surface of the first encapsulant to be exposed to outside of the second encapsulant and level with a surface of the second encapsulant, whereby the injection-molded second encapsulant prevents resin flash over the exposed terminals that may be electrically connected to an external device, thereby assuring quality of the electrical connection with the external device.
