SiC Wafer Grinding - Engis Corporation
Grinding; Lapping (1 or 2 steps) Polish and Chemical-Mechanical Polishing (CMP) Silicon Carbide Wafer Grinding. The EVG-250/300 series Vertical Grinding Machine combined with Engis MAD Grinding Wheels can achieve a superior surface finish on silicon carbide wafers to reduce or even eliminate loose abrasive lapping steps.
Wafer Backgrinding | Silicon Wafer Thinning | …
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.

Back grinding is a process that removes silicon from the back surface of a wafer. Silicon Valley Microelectronics provides grinding on our own substrates or on customer supplied wafers. We process bare and device patterned wafers with high yield and offer wafer thinning to customer specifications. SVM Wafer Back Grinding Capabilities:
Wafer backgrinding - Wikipedia
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.

Fine grinding of silicon wafers - Kansas State University
Fine grinding of silicon wafers requires high predictability and consistency, which requires the grinding wheel to possess self-dressing ability, i.e., after initial truing, the wheel should not need any periodic dressing by external means. In other words, there should be “a perfect equilibrium

Grinding of silicon wafers: A review from historical ...
It is intended to help readers to gain a more comprehensive view on grinding of silicon wafers, and to be instrumental for research and development in grinding of wafers made from other materials (such as gallium arsenide, germanium, lithium niobate, sapphire, and silicon carbide).
Grinding Machine for Semiconductor Wafers.
Double side grinding is a single wafer operation and all silicon wafers will have the same thickness after this process. Ground wafers can be transferred to polishing without sorting procedures. Full tracking of wafers through all production steps becomes much easier, using this technology.
Wafer grinding, ultra thin, TAIKO - dicing-grinding …
Partial Wafer Grinding is an efficient grinding method to process broken or damaged wafers, or wafer sections. This technique can be employed to process wafers that had been damaged, or wafer sections that are still intact, thereby avoiding loss of the entire wafer material.
