The present technology is directed toward semiconductors packaged by electrically coupling a plurality of die to an upper and lower lead frame. The opposite edges of each corresponding set of leads in the upper lead frame are bent. The leads in the upper lead frame are electrically coupled between respective contacts on respective die and respective lower portion of the leads in the lower lead frame. The bent opposite edges of each corresponding set of leads of the upper lead frame support the upper lead frame before encapsulation, for achieving a desired position of the plurality of die between the leads of the upper and lower lead frames in the packaged semiconductor. After the encapsulated die are separated, the upper leads have an L-shape and electrically couple die contacts on upper side of the die to leads on the lower side of the die so that the package contacts are on the same side of the semiconductor package.

The radiation performance of a resin sealed semiconductor package is enhanced and further the fabrication yield thereof is enhanced. A drain terminal coupled to the back surface drain electrode of a semiconductor chip is exposed at the back surfaceof an encapsulation resin section. Part of the following portion and terminal is exposed at the top surface of the encapsulation resin section: the first portion of a source terminal coupled to the source pad electrode of the semiconductor chip and a gate terminal coupled to the gate pad electrode of the semiconductor chip. The remaining part of the second portion of the source terminal and the gate terminal is exposed at the back surface of the encapsulation resin section. When this semiconductor device is manufactured, bonding material and a film member are placed between the drain terminal and the semiconductor chip. At the same time, paste-like bonding material and a film member are placed between the source terminal 3 and gate terminal and the semiconductor chip. The paste-like bonding material is cured and turned into bonding material. As the result of use of the film members, variation in the thickness of the bonding material is suppressed.
