  • HOW TO MAKE A SILICON WAFER

    HOW TO MAKE A SILICON WAFER A wafer is a slice of silicon roughly 1 millimeter thick that has an extremely flat surface thanks to procedures that are technically very demanding. The subsequent use determines which crystal growing procedure should be employed. In the Czochralski process, for examp...
