Abstract
A semiconductor device and method of manufacturing the same includes the steps of forming silicon nitride films including much silicon than a stoichiometric silicon nitride (Si.sub.3 N.sub.4) and which will be an anti-reflection film, forming a resist film on the plasma silicon nitride films and, and concurrently patterning plasma silicon nitride films and conductive layers and using the resist film as a mask. As a result, high integration of the semiconductor device can be attained.
