A backside grinding apparatus removes semiconductor material from a surface of a semiconductor wafer. The wafer is mounted to a backing plate. The backside surface undergoes a first grinding operation in a rotational motion to remove excess semiconductor material. The semiconductor wafer is then aligned such that edges of the die are oriented along a reference line.

grinding wheel (small mesh) in order to remove the bulk of the Si at high speed (in the order of a few µm per second). Yet, it causes deep SSD due to the brittle nature of the Si wafer in combination with the big grit size. This damage layer is typically confined to the first 20 µm below the ground surface. A fine grinding .
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.
