High Frequency Gallium Arsenide Mmic Die Coating Method

US Patent:

6531344, Mar 11, 2003

Filed:

Jul 6, 2000

Appl. No.:

09/611043

Inventors:

Ken Brice-Heames - Mesa AZ
James Landers - Mesa AZ
Ronald Dee Fuller - Mesa AZ

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H01L 2156

US Classification:

438127, 438780, 427 96

Abstract:

A moisture resistant conformal coating ( ) effectively protects high frequency circuits such as gallium arsenide MMICs from humidity and environmental contamination without the performance degradation inherent in conventionally applied conformal coatings. The conformal coating preferably comprises an organic polymer, such as silicone, applied to the MMIC die in a substantially uniform thickness of less than 0. 002 inches, preferably of less than 0. 0015 inches. This is accomplished by applying the organic polymer directly to the surface of the die ( ) in a mixture containing the solid organic polymer diluted with a low surface tension solvent, such as a volatile methyl siloxane.

Transparent Compound And Applications For Its Use

US Patent:

6246123, Jun 12, 2001

Filed:

May 4, 1998

Appl. No.:

9/072053

Inventors:

James F. Landers - Mesa AZ
Robert K. Denton - Winchester VA

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H01L 2328

US Classification:

257787

Abstract:

A mold compound made from a polymer resin and an isorefringent, transparent filler is used to form optical electronic components (10, 20, 30). The mold compound can be used to form a lens (13) on a display device (10), to form the outer housing (21) of a waveguide (20), or to form a dome (34) that reflects light from a light emitting device (32) to a light detecting device (33).
