Filed:

Oct 20, 1988

Appl. No.:

7/262244

Inventors:

Dagobert M. de Leeuw - White Plains NY
Walter K. Zwicker - Scarborough NY
Rameshwar N. Bhargava - Ossining NY

Assignee:

North American Philips Corporation - New York NY

International Classification:

B05D 506

US Classification:

427 64

Abstract:

Luminescent thin films are produced by a sol-gel process in which a gellable liquid is applied to a substrate to form a thin film, gelled and heated to remove volatile constituents and form a polycrystalline luminescent material.

International Classification:

H01G 101
H01G 410

US Classification:

361321

Abstract:

A thin film capacitor is formed of a thin crystalline electrically insulative or semiconductive substrate. With the insulative substrate a thin conductive metal layer is deposited on the substrate and a thin film of a crystalline strontium barium niobate deposited on the thin conductive metal layer so that its 2. 77. ANG. spaced atomic planes are oriented in a non-perpendicular manner to the substrate and an additional thin conductive layer is deposited on the surface of the strontium barium niobate film. When a semiconductive substrate is employed the strontium barium niobate film is deposited directly on the substrate. These capacitors exhibit a low temperature coefficient of capacitance and a high capacitance density.
