  • Publication number: 20250079177
    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

  • Publication number: 20010048549
    Abstract: A camera adapter for microscope compromising a sleeve with an internal lens tube replacing the eyepiece of a microscope and placed on the location of eyepiece. There is a thumbscrew on lower portion of the sleeve to fix the sleeve firmly on the location of eyepiece. There is a connecting ring on top of the sleeve. On the top outer rim surface of the connecting ring covers with threads, external camera can tie to the sleeve through the threads. Based on above description, an external camera can tie to a microscope by connecting the camera on the threads of the connecting ring of the sleeve. This is for connecting an external camera to a microscope without a third eyepiece.
