Back Grinding Machines In Semiconductor
Semiconductor BackGrinding The silicon wafer on which the active elements are created is a thin circular disc typically 150mm or 200mm in diameter During diffusion and similar processes the wafer may become bowed but wafers for assembly are normally stress relieved and can be regarded as flat grinding machines for semiconductor wafers koyo
