Fabrication Of Devices Using Phosphorus Glasses

US Patent:
4731293, Mar 15, 1988
Filed:
Jun 20, 1986
Appl. No.:
6/876442
Inventors:
David T. Ekholm - Mountainside NJ
William H. Grodkiewicz - Glen Gardner NJ
Bertram Schwartz - Westfield NJ
Shobha Singh - Summit NJ
LeGrand G. Van Uitert - Morris Township, Morris County NJ
George J. Zydzik - Columbia NJ
Assignee:
American Telephone and Telegraph Company, AT&T Bell Laboratories - Murray Hill NJ
International Classification:
B32B 1706
US Classification:
428426
Abstract:
A fabrication technique is described for making various devices in which a type of glass is used as a surface protection layer. The glass layers are put down by particle bombardment (generally sputtering or e-beam bombardment) of a phosphorus-containing silicate glass target. Devices with such layers are also described. Such glass layers are highly advantageous as encapsulating material, diffusion barrier layers, etc. , particularly for optical type devices and certain semiconductor devices. Particularly important is the preparation procedure for the glass target used in the bombardment process. The glass layers are moisture stable, act as excellent barriers against diffusion, and are usable up to quite high temperatures without cracking or peeling. The glass layers also provide long-term protection against atmosphere components including water vapor, oxygen, atmosphere pollution contaminants, etc.
