Abstract

According to this invention, a method of manufacturing a semiconductor device includes the steps of forming a carbon film on a surface of a substrate, forming a mask pattern on the carbon film, etching the carbon film along the mask pattern to form a carbon film pattern, and reactive ion etching the substrate along the carbon film pattern using a high density plasma produced by application of a high frequency and a magnetic field, application of a microwave, irradiation of an electron beam, application of a high frequency of not less than 27 MHz, or application of a inductive coupled high frequency.
