摘要:
A semiconductor device including a plurality of leads respectively made up of an inner lead and an outer lead, a semiconductor chip electrically connected to the inner leads, and a package encapsulating at least the inner leads of the leads and the semiconductor chip so that the outer leads extend outwardly of the package. The package has an upper part and a lower part which have mutually different sizes such that a stepped part is formed between the upper and lower parts by the different sizes, and each of the outer leads have a wide part which is wider than other parts of the outer lead extending outwardly of the package only within the stepped part of the package.

A semiconductor device having a package of a single in-line type includes a semiconductor chip, a package body that accommodates the semiconductor chip therein and defined by a pair of opposing major surfaces and a plurality of interconnection leads held by the package body to extend substantially perpendicularly to a bottom surface. Each of the interconnection leads consists of an inner lead part located inside the package body and an outer lead part located outside the package body, the outer lead part being bent laterally at a boundary between the inner part and the outer part, in one of first and second directions that are opposite from each other and substantially perpendicular to the opposing major surfaces of the package body. A plurality of support legs extend laterally at the bottom surface of the package body for supporting the package body upright when the semiconductor device is placed on a substrate.
