Patent ID: 7045906

Claim:
A resin-encapsulated package having terminals, including some exposed terminals, the resin-encapsulated package comprising: a semiconductor IC chip sealed in a resin molding; and a lead member comprising a plurality of discrete terminal sections; wherein: each of the terminal sections includes an inner terminal part for electrical connection to a terminal of the semiconductor IC chip, an outer terminal part for connection to an external circuit, and a connecting part joining the inner terminal part and the outer terminal part; the inner terminal part includes a first contact surface, the outer terminal part includes a second contact surface, and the first contact surface and the second contact surface face in opposite directions; the inner terminal part has a first thickness, the connecting part has a second thickness, the outer terminal part has a third thickness, and the third thickness is greater than each of the first thickness and the second thickness; the first contact surface of each terminal section of the lead member is substantially coplanar with the first contact surfaces of the other terminal sections; a surface of the semiconductor IC chip having terminals faces a surface of the lead member including the first contact surfaces; the terminals of the semiconductor IC chip are joined to or in contact with the first contact surfaces of the lead member; the terminals of the semiconductor IC chip are electrically connected to the inner terminal parts of the lead member; each of the first contact surfaces comprises a plated metal layer, and the terminals of the semiconductor IC chip are electrically connected to the inner terminal parts of the lead member through the plated metal layers; and the plated metal layers are formed only on portions of the first contact surfaces facing the terminals of the semiconductor IC chip.
