Abstract:
The method of this invention provides a method for manufacturing a capacitor element composed of films. The films have a precise etched shape without a residue that may be generated as a reaction product in a dry-etching process. In this invention, washing in a non-oxidizing atmosphere, inclining a side of a mask for etching or heating a substrate prevents the reaction product from remaining on the film as a residue. The reaction product can be washed away with water, acid or organic solvent in inert gas. The reaction product can be removed from the side of the mask by sputter-etching with ions for dry-etching. The reaction product can be exhausted without adhering to the mask by heating the substrate at a temperature between 100.degree. C. and 400.degree. C.

A semiconductor device forming a capacitor through an interlayer insulating layer on a semiconductor substrate on which an integrated circuit is formed. This semiconductor device has an interlayer insulating layer with moisture content of 0.5 g/cm.sup.3 or less, which covers the capacitor in one aspect, and has a passivation layer with hydrogen content of 10.sup.21 atoms/cm.sup.3 or less, which covers the interconnections of the capacitor in other aspect.
