Abstract

In gas panel fabrication, orthogonal conductor arrays are formed on glass plates and the conductors are then overcoated with a dielectric. A method of fabrication using aluminum conductors operates as follows. By anodizing an aluminum film on substrate glass, a conductor pattern can be formed. About 7 microns of aluminum are deposited on the gas panel substrate glass. A photoresist conductor pattern is applied, and the part is anodized in oxalic acid solution. The unprotected aluminum is oxidized to aluminum oxide, which is a clear dielectric material. The portion of the pattern covered by photoresist remains unoxidized and forms the aluminum conductors. After stripping the photoresist, the aluminum conductors are partially anodized to cover the conductor with the aluminum-oxide dielectric.

Aluminum-Aluminum Oxide Gas Panel

In gas panel fabrication, orthogonal conductor arrays are formed on glass plates and the conductors are then overcoated with a dielectric. A method of fabrication using aluminum conductors operates as follows. By anodizing an aluminum film on substrate glass, a conductor pattern can be formed. About 7 microns of aluminum are deposited on the gas panel substrate glass. A photoresist conductor pattern is applied, and the part is anodized in oxalic acid solution. The unprotected aluminum is oxidized to aluminum oxide, which is a clear dielectric material. The portion of the pattern covered by photoresist remains unoxidized and forms the aluminum conductors. After stripping the photoresist, the aluminum conductors are partially anodized to cover the conductor with the aluminum-oxide dielectric. This dielectric, which covers the conductors and separates them and is required to provide proper operating characteristics, also acts as a an anti-glare coating.
