Solder bumps are placed in direct contact with the silicon substrate of an amplifier integrated circuit having a flip chip configuration. A plurality of amplifier transistor arrays generate waste heat that promotes thermal run away of the amplifier if not directed out of the integrated circuit. The waste heat flows through the thermally conductive silicon substrate and out the solder bump to a heat-sinking plane of an interposer connected to the amplifier integrated circuit via the solder bumps.

Implementations of a semiconductor device may include a semiconductor die including a first largest planar surface, a second largest planar surface and a thickness between the first largest planar surface and the second largest planar surface; and one of a permanent die support structure, a temporary die support structure, or any combination thereof coupled to one of the first largest planar surface, the second largest planar surface, the thickness, or any combination thereof where the semiconductor die may be coupled with one of a substrate, a leadframe, an interposer, a package, a bonding surface, or a mounting surface. The thickness may be between 0.1 microns and 125 microns.

The present disclosure provides a semiconductor device and a method of manufacturing a semiconductor device. The semiconductor device includes a substrate, a conductive feature, a redistribution layer, at least one through silicon via and at least one bump. The conductive feature is disposed over a front surface of the substrate, and the redistribution layer is disposed over a back surface opposite to the front surface. The through silicon via penetrates through the substrate and contacts the conductive feature embedded in an insulative layer. The bump contacts the redistribution layer and the through silicon via and serves as an electrical connection therebetween.
