Packaged semiconductor device having multilevel leadframes configured as modules

摘要

A semiconductor system (100) has a first planar leadframe (101) with first leads (102) and pads (103) having attached electronic components (120), the first leadframe including a set of elongated leads (104) bent at an angle away from the plane of the first leadframe; a second planar leadframe (110) with second leads (112) and pads (113) having attached electronic components (114); the bent leads of the first leadframe conductively connected to the second leadframe, forming a conductively linked 3-dimensional network between components and leads in two planes; and packaging material (140) encapsulating the 3-dimensional network.
