Dear Group, I am working on a project that requires planarization of a CVD oxide layer on 4 inch substrates. I have spoken with Sandia about their CMP capabilities but they are set up for 6 inch substrates. Does anyone know of a source for CMP on 4 inch wafers? Any suggestions would be appreciated.
