Patent ID: 7456494

Claim:
A surface mount electronic component comprising: a set of a first lead terminal and a second lead terminal; a semiconductor element die-bonded to an upper surface of an island portion integrally formed at an end of the first lead terminal; a metal wire electrically connecting the semiconductor element and an upper surface of a bonding portion integrally formed at an end of the second lead terminal to each other; and a package made of synthetic resin and hermetically sealing the island portion and the bonding portion; wherein the island portion of the first lead terminal and the bonding portion of the second lead terminal are formed by plastic deformation of a portion of each of the lead terminals to be positioned within the package, the plastic deformation being performed from a lower surface side to reduce thickness and increase width while keeping upper surfaces of the island portion and the bonding portion flush or generally flush with upper surfaces of the lead terminals, and wherein a portion of a lower surface of each of the first lead terminal and the second lead terminal which is not subjected to the plastic deformation is exposed at a lower surface of the package to serve as a mount surface for soldering.
