Abstract:
A semiconductor assembly including:a semiconductor device having opposed longer peripheral sides and opposed ends, an active surface in substantially a first horizontal plane, an inactive bottom surface in substantially a second horizontal plane, and a plurality of bonds pads located on the active surface of the semiconductor device, a first portion of the plurality of bond pads located adjacent one of the opposed longer peripheral sides and a second portion of the plurality of bond pads located adjacent another of the opposed longer peripheral sides; and a lead frame comprising: a first plurality of lead fingers extending substantially in the first horizontal plane of the active surface of the semiconductor device, each lead finger of the first plurality of lead fingers terminating in an end located adjacent a longer peripheral side of the opposed longer peripheral sides of the semiconductor device; and a second plurality of lead fingers extending below the inactive bottom surface of the semiconductor device, each lead finger of the second plurality of lead fingers having a portion thereof extending adjacent an end of the opposed ends of the semiconductor device and terminating in an end located adjacent a longer peripheral side of the opposed longer peripheral sides of the semiconductor device, some of the second plurality of lead fingers forming a die paddle for locating the semiconductor device thereon, a plurality of lead fingers of the second plurality of lead fingers each having a portion thereof extending adjacent a portion of a lead finger of the first plurality of lead fingers, a portion thereof extending substantially adjacent an end of the opposed ends of the semiconductor device, a portion extending substantially opposed to an end of the opposed ends of the semiconductor device and extending adjacent a portion of the die paddle, and having a portion extending beyond a side of the opposed longer peripheral sides of the semiconductor device.
