Various methods of attaching a lid to an integrated circuit substrate are provided. In one aspect, a method of attaching a lid to a substrate that has an integrated circuit positioned thereon is provided. An adhesive is applied to the substrate and an indium film is applied to the integrated circuit. The lid is positioned on the adhesive. The adhesive is partially hardened and the indium film is reflowed. The adhesive is cured.

Lid attach process

Thermal interface materials and method of using the same in packaging are provided. In one aspect, a thermal interface material is provided that includes an indium preform that has a first surface and a second surface opposite to the first surface, an interior portion and a peripheral boundary. The indium preform has a channel extending from the peripheral boundary towards the interior portion. The channel enables flux to liberate during thermal cycling.

Void reduction in indium thermal interface material

A semiconductor component having a lid for protecting a semiconductor chip and a method for manufacturing the semiconductor component. The semiconductor chip has an active surface and a mounting surface. It is flip-chip mounted to a support substrate so the active surface is adjacent the support substrate. A passive or active circuit element may be mounted to the support substrate. The mounting surface of the semiconductor chip has a radius of curvature. A thermal interface material is dispensed on the mounting surface of the semiconductor chip. A lid is coupled to the support substrate via a lid adhesive. A portion of the lid has a radius of curvature that corresponds to the radius of curvature of the semiconductor chip. A force is applied to the lid so that it contacts the thermal interface material and urges the interface material to the sides of the semiconductor chip. The force causes wetting of the thermal interface material.

Semiconductor component and method of manufacture

An integrated circuit package having a die supported on a ball grid array substrate and wire bonds electrically connecting the die to the substrate. Supported on the substrate is a lock ring having a threaded opening encircling the die. Encapsulant covers the die and the wire bonds and adheres the lock ring to the substrate. A heat sink having a threaded portion can be threaded into the lock ring into an operative cooling position relative to the die and subsequently to an unthreaded removed position. When in the latter position, a repair station can be positioned over the package and the solder balls are accessible for hot gas melting thereof for removal (or replacement) of the package from the underlying motherboard.
