Abstract:
An electronic device is described comprising at least one chip enclosed in a package, in turn provided with a metallic structure or leadframe having a plurality of connection pins, this chip having at least one first contact realized on a first face and at least one second contact realized on a second and opposite face of this chip. The chip comprises at least one through via crossing the whole section of the chip as well as a metallic layer extending from the second contact arranged on the first face, along walls of the at least one through via up to the second and opposite face in correspondence with an additional pad. The electronic device comprises at least one interconnection layer for the electrical and mechanical connection between the chip and the metallic structure having at least one portion realized in correspondence with the at least one through via so as to bring the second contact placed on the second face of the chip back on its first face. An assembly process of such an electronic device is also described.
Abstract:
Packaged semiconductor device having a frame, of conductive material; a body of semiconductor material, fixed to the frame through a first adhesive layer; a heatsink element, fixed to the body through a second adhesive layer; and a packaging mass surrounding the body and, at least partially, the frame and the heatsink element. The heatsink element is formed by a heatsink die facing, and coplanar to, a main face of the device and by a spacer structure, which includes a pair of pedestals projecting from the perimeter of the heatsink die towards the body and rest on the body.

Abstract:
A system includes a device of the surface-mounting type having an insulating package provided with a mounting surface and a contact pin exposed on the mounting surface. The device is attached to an insulating board including a gluing surface and an opposite surface. The process for manufacturing the system includes forming through holes a contact region on the gluing surface. The mounting surface is glued to the gluing surface with the contact pin aligned with the contact region. Wave soldering is performed to electrically join the device to the board by hitting the opposite surface with a wave of soldering paste to form, by capillary action with the soldering paste ascending in the through holes up to the overflow on the gluing surface, a conductive contact electrically connecting the contact pin of the electronic device through a solder connection to the contact region of the electronic board.
