Hi everybody: Does anyone know where to buy the MicroSi, CEM 388S? The 'CEM' means Contrast Enhancement Material. It is used following the PR. I know the CEM from papers. In general it is used in submicro-um process. But it also work well for the high aspect ratio process. If somebody know the telephone or Fax of the MicroSi, please let me know. Thanks a lot.
