Semiconductor Back-Grinding 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.

Grinders can thin silicon wafers, compound semiconductors, and many other types of materials with a high degree of accuracy. Processing for applications which use the DBG system or DAF (Die attach film) is also possible by incorporating a polisher and wafer mounter with the grinder into an inline system*.
