Abstract: To deposit optical quality films by PECVD (Plasma Enhanced Chemical Vapor Deposition), a six-dimensional space wherein five dimensions thereof correspond to five respective independent variables of which a set of four independent variables relate to the flow-rate of respective gases, a fifth independent variable relates to total pressure, and a six dimension relates to observed FTIR characteristics is first created. Then an optical film is deposited while maintaining three of the set of four independent variables substantially constant as well as the fifth independent variable, and varying a fourth of the set of four independent variables to obtain desired characteristics in the sixth dimension.

Abstract: Thick dielectric films are deposited on a substrate by building up a plurality of layers by PECVD (Plasma Enhanced Chemical Vapor Deposition) in a reactor, each layer having a thickness less than the final thickness of the film to be deposited. The reactor is cleaned between the deposition of each layer. In this way, it is possible to form high quality, optical films.

Abstract: A method of depositing an optical quality silica film on a substrate is described wherein the film is formed on the substrate by plasma enhanced chemical vapor deposition (PECVD) in the presence of reactive gases while controlling the total pressure of the gases. The as-deposited film is then subjected to a low temperature treatment between 400° to 1200° C. to minimize the presence of contaminant compounds in the film.

Abstract: A method of forming capacitors in a semiconductor device, involves providing a first insulating layer, providing a first mask with an array of apertures over the insulating layer, and etching an array of holes in the first insulating layer through said apertures in said first mask. A first electrode layer extending into the holes is formed over the first insulating layer. A second dielectric layer extends into the holes on said first electrode layer. A second electrode layer extends into the holes on the dielectric layer. The capacitors are patterned with a second mask. The capacitors can be subsequently connected into the circuit in a sequence of processing steps that only involve the addition two extra masks beyond those conventionally employed in integrated circuit manufacture.
