Abstract:
A semiconductor device is made by forming solder bumps over a copper carrier. Solder capture indentations are formed in the copper carrier to receive the solder bumps. A semiconductor die is mounted to the copper carrier using a die attach adhesive. The semiconductor die has contact pads formed over its active surface. An encapsulant is deposited over the copper carrier, solder bumps, and semiconductor die. A portion of the encapsulant is removed to expose the solder bumps and contact pads. A conductive layer is formed over the encapsulant to connect the solder bumps and contact pads. The conductive layer operates as a redistribution layer to route electrical signals from the solder bumps to the contact pads. The copper carrier is removed. An insulating layer is formed over the conductive layer and encapsulant. A plurality of semiconductor devices can be stacked and electrically connected through the solder bumps.
Abstract:
A semiconductor device is made by mounting a prefabricated heat spreader frame over a temporary substrate. The heat spreader frame includes vertical bodies over a flat plate. A semiconductor die is mounted to the heat spreader frame for thermal dissipation. An encapsulant is deposited around the vertical bodies and semiconductor die while leaving contact pads on the semiconductor die exposed. The encapsulant can be deposited using a wafer level direct/top gate molding process or wafer level film assist molding process. An interconnect structure is formed over the semiconductor die. The interconnect structure includes a first conductive layer formed over the semiconductor die, an insulating layer formed over the first conductive layer, and a second conductive layer formed over the first conductive layer and insulating layer. The temporary substrate is removed, dicing tape is applied to the heat spreader frame, and the semiconductor die is singulated.

Abstract:
A semiconductor device is made by providing a semiconductor die having an optically active area, providing a leadframe or pre-molded laminated substrate having a plurality of contact pads and a light transmitting material disposed between the contact pads, attaching the semiconductor die to the leadframe so that the optically active area is aligned with the light transmitting material to provide a light transmission path to the optically active area, and disposing an underfill material between the semiconductor die and leadframe. The light transmitting material includes an elevated area to prevent the underfill material from blocking the light transmission path. The elevated area includes a dam surrounding the light transmission path, an adhesive ring, or the light transmission path itself can be the elevated area. An adhesive ring can be disposed on the dam. A filler material can be disposed between the light transmitting material and contact pads.

A second semiconductor die is mounted to the first conductive layer opposite the first die. A second encapsulant is deposited over the second die and semiconductor package. A second via is formed in the second encapsulant to expose the conductive bump. A second conductive layer is formed over the second encapsulant and into the second via. The second conductive layer is electrically connected to the second die.
