Packaged semiconductor device

Claim 2

A packaged semiconductor device comprising: a resin package having a generally rectangular shape with a pair of opposed longer sides and a pair of opposed shorter sides; a semiconductor device contained within said resin package, said semiconductor device having a plurality of terminals oriented along said shorter sides of said resin package; a pad to which said semiconductor device is bonded within said resin package; a plurality of leads extending outwardly from the shorter sides of said resin package generally parallel to said longer sides, each lead having an inner end disposed within said package in the vicinity of one of said terminals; a plurality of lead wires respectively connecting each of said plurality of terminals of said semiconductor device to one of said plurality of leads at said inner end within said resin package; and two pairs of pad leads extending from said pad for supporting said pad on a frame while said semiconductor device is being bonded to said pad during assembly of said packaged semiconductor device wherein said pad leads are disposed generally parallel to said shorter sides and extend to said longer sides of said packaged device.

Claim 3

The packaged semiconductor device according to claim 1 wherein said pad and semiconductor device are generally rectangular and respectively have a pair of opposed longer pad and device edges generally parallel to said pair of opposed longer sides of said resin package and a pair of opposed shorter pad and device edges generally parallel to said pair of opposed shorter sides of said resin package and each of said pairs of pad leads is disposed proximate a respective shorter pad edge for stabilizing said pad during assembly of said packaged semiconductor device.

Claim 4

A packaged semiconductor device comprising; a resin package having a generally rectangular shape with a pair of opposed longer sides and a pair of opposed shorter sides; a semiconductor device contained within said resin package, said semiconductor device having a plurality of terminals oriented along said shorter sides of said resin package; a pad to which said semiconductor device is bonded within said resin package; a plurality of leads extending outwardly from the shorter sides of said resin package generally parallel to said longer sides, each lead having an inner end disposed within said package in the vicinity of one of said terminals, at least one of said leads including a widened portion extending from said inner end toward one of said longer sides proximate the respective terminal, the widened portion being trapezoidal in shape and including a first edge generally parallel to said longer sides and a second edge, intersecting said first edge, diagonal to said longer and shorter sides wherein the inner end of the lead disposed adjacent said lead including a trapezoidal widened portion includes an inner end disposed generally parallel to and spaced from said second edge; pad leads extending from said pad for supporting said pad on a frame while said semiconductor device is being bonded to said pad during assembly of said packaged semiconductor device wherein said pad leads are disposed generally parallel to said shorter sides and extend to said longer sides of said packaged device.

Claim 5

A packaged semiconductor device comprising; a resin package having a generally rectangular shape with a pair of opposed longer sides and a pair of opposed shorter sides; a semiconductor device contained within said resin package, said semiconductor device having a plurality of terminals oriented along said shorter sides of said resin package; a pad to which said semiconductor device is bonded within said resin package; a plurality of leads extending outwardly from the shorter sides of said resin package generally parallel to said longer sides, each lead having an inner end disposed within said package in the vicinity of one of said terminals, at least one of said leads including a widened portion extending from said inner end toward one of said longer sides proximate the respective terminal, the widened portion being trapezoidal in shape and including a first edge generally parallel to said longer sides and a second edge, intersecting said first edge, diagonal to said longer and shorter sides wherein the inner end of the lead disposed adjacent said lead including a trapezoidal widened portion includes an inner end disposed generally parallel to and spaced from said second edge; pad leads extending from said pad for supporting said pad on a frame while said semiconductor device is being bonded to said pad during assembly of said packaged semiconductor device wherein said pad leads are disposed generally parallel to said shorter sides and extend to said longer sides of said packaged device.

Claim 6

The packaged semiconductor device according to claim 3 including a plurality of leads having trapezoidal widened inner lead portions disposed proximate respective terminals along both shorter sides of said package.

Claim 7

The packaged semiconductor device according to claim 4 wherein the trapezoidal widened portions of two adjacent leads at one of said shorter sides are respectively disposed toward opposite ones of said longer sides.
