  • METHOD OF MANUFACTURING A SEMICONDUCTOR DEVICE
    Publication number: 20220270886
    Abstract: In a method of manufacturing a semiconductor device, a mask pattern is formed over a target layer to be etched, and the target layer is etched by using the mask pattern as an etching mask. The etching is performed by using an electron cyclotron resonance (ECR) plasma etching apparatus, the ECR plasma etching apparatus includes one or more coils, and a plasma condition of the ECR plasma etching is changed during the etching the target layer by changing an input current to the one or more coils.
    Type: Application
