Wafer grinding, also called wafer thinning, is a process performed during the semiconductor manufacturing to reduce wafer thickness. This manufacturing step is essential in producing the ultra-thin wafers required for stacking and high-density packaging in portable and handheld devices.

Wafer backgrinding is a semiconductor device fabrication step during which wafer thickness is reduced to allow stacking and high-density packaging of integrated circuits (IC). ICs are produced on semiconductor wafers that undergo a multitude of processing steps. The silicon wafers predominantly used today have diameters of 200 and 300 mm. They are roughly 750 μm thick to ensure a minimum of mechanical stability and to avoid warping during high-temperature processing steps.

Grinding Machines for Semiconductor Wafers. Koyo Machine Industries developed several types of grinding machines, used in the semiconductor industry for silicon wafer manufacturing and IC production. Vertical and horizontal spindle systems are used in combination with special designed diamond grinding wheels, that cut just at the edge of the

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.

In the context of manufacturing integrated circuits, wafer dicing is the process by which die are separated from a wafer of semiconductor following the processing of the wafer. The dicing process can involve scribing and breaking, mechanical sawing (normally with a machine called a dicing saw) or laser cutting.All methods are typically automated to ensure precision and accuracy.

Heat resistance back grinding tape can correspond to the secondary process of wafer backside. After the back-grinding process, the wafers with the heat resistance back grinding tape can be processed (wet etching, ashing, metalizing, exposure/processing and so on).
