In small diamter wafering process, wafers are sliced one by one from the ingot using a rotating diamond inner peripheral blade. The image shown on left is slicing with wire-saw. Beveling (Peripheral Rounding) The periphery of a wafer is ground with a diamond tool to attain the required product diameter.

One option is to planar grind the specimens with a conventional alumina or Silicon carbide grinding stone. This requires a special purpose machine, as the stone must rotate at a high speed, ≥1500 rpm, to cut effectively.

Grinding Machine Definition: A grinding machine is a production machine tool used in the manufacturing industry in which the grinding wheel is attached in the tool post and the workpiece is fixed to the work table and when the operation starts it removes the unwanted material to get the desired surface finish, correct size, and accurate shape of the workpiece.

TSV (through silicon via) is regarded as a key technology for 2.5D and 3D electronic packaging. And the manufacturing of the through silicon interposer is very challenge and costly.
