Filed:

Apr 5, 2004
Appl. No.:

10/818981
Inventors:

Seah Sun Too - San Jose CA, US
James Hayward - Santa Clara CA, US
Janet D. Kirkland - Fremont CA, US
Assignee:

Advanced Micro Devices, Inc. - Sunnyvale CA
International Classification:

H01L023/12
US Classification:

438122, 438106, 257704, 257706, 257713, 257724
Abstract:

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.

International Classification:

H01L 21/00
US Classification:

438106, 438118
Abstract:

A method for coupling a lid to a support substrate having a semiconductor chip coupled thereto and a clamp fixture. Each semiconductor component has a semiconductor chip mounted to a semiconductor component and a lid coupled to the support substrate via a lid attach material. The lid attach material is cured either using a two-step process that includes a partial cure step followed by a clampless cure step or by curing the die attach material in a clamp fixture without including a pre-cure step. The semiconductor component manufacture decides on the curing approach based on cost and the number of semiconductor components being manufactured. If the semiconductor manufacturer opts for curing with a clamp fixture, the clamp fixture includes a base plate insert on which the semiconductor components are placed and a compression mechanism that includes a compression plate having a compressive material disposed thereon.
