Title:
LOW-RELATIVE-DIELECTRIC CONSTANT INSULATING FILM, FORMATION THEREOF, AND INTERLAYER INSULATING FILM
Document Type and Number:
Japanese Patent JPH11289011
Kind Code:
A
Abstract:

To provide a low-relative-dielectric constant insulating film which can have stable characteristics, a high adhesion to a metallic wiring layer and a high resistance to plasma, and can be suitably used as an interlayer insulating film.

The low-relative-dielectric constant insulating film includes a semiconductor substrate 21, an aromatic polyimide film 25 formed on the substrate 21 and containing a predetermined amount of fluorine, and inorganic insulating films 24A and 24B having a thickness of 1/10 or less (100 nm or less) of a thickness of the polyimide film 25 and formed on both surfaces of the film 25 as closely adhered thereto. The inorganic insulating films contain one or more selected from a group of SiO2, Si3N4 and glass.
