"ULTRA FLAT SILICON WAFER 4"",EA"

Ultra-Flat 4" Silicon Wafers

Ultra-Flat 4" Silicon Wafer for demanding substrate studies. Can also be used as substrate for AFM or SEM samples by dicing the wafer into smaller pieces using a scriber and the Wafer Cleaving / Glass Breaking Pliers. The 4" ultra-flat silicon wafer is shipped in a  4" wafer carrier.
