US Patent:

8617913, Dec 31, 2013

Filed:

Sep 29, 2008

Appl. No.:

12/240775

Inventors:

Nathan P. Lower - North Liberty IA, US
Alan P. Boone - Swisher IA, US
Ross K. Wilcoxon - Cedar Rapids IA, US
David D. Hillman - Cedar Rapids IA, US

Assignee:

Rockwell Collins, Inc. - Cedar Rapids IA

International Classification:

H01L 21/00

US Classification:

438 57, 438 72, 438127

Abstract:

A coating for reducing interaction between a surface and the environment around the surface includes an alkali silicate glass material configured to protect the surface from environmental corrosion due to water or moisture. The alkali silicate glass material is doped with a first element to affect various forms of radiation passing through the coating. The electromagnetic radiation is at least one of ultraviolet, x-ray, atomic (gamma, alpha, beta), and electromagnetic or radio wave radiation. The coating may also be used to protect a solar cell from the environment and UV rays while retransmitting received light as usable light for conversion into electrical energy. The coating may also be used to prevent whisker formation in metal finishes of tin, cadmium, zinc, etc.

Abstract:

High strength gold wire for use in microelectronics and a method of producing the same are disclosed. In the methods of the present invention, a gold alloy having gold and a dilute rare earth (RE) element is produced. Next, the gold alloy is atomized into a powder. The dilute RE element is at least partially oxidized during atomization. Then, the powder is consolidated into an oxide dispersion strengthened gold billet. Finally, gold wire is formed from the oxide dispersion strengthened gold billet. The high strength gold wire can be drawn to a diameter less than conventional gold wire, while still maintaining mechanical and electrical properties, thereby facilitating microelectronics miniaturization.
