Grinding wheel - Wikipedia

A grinding wheel is a wheel composed of an abrasive compound and used for various grinding (abrasive cutting) and abrasive machining operations. Such wheels are used in grinding machines.. The wheels are generally made from a composite material consisting of coarse-particle aggregate pressed and bonded together by a cementing matrix (called the bond in grinding wheel terminology) to form a ...

Wafer dicing - Wikipedia

Wafer grinding may be performed after this step, to reduce die thickness. Dice before grind. The DBG or "dice before grind" process is a way to separate dies without dicing. The separation occurs during the wafer thinning step. The wafers are initially diced using a …

Products – Siltronic / perfect silicon solutions

The final step is grinding orientation markings, such as notches for large-diameter wafers or straight edges (flats) on the side of small wafers. Wire slicing The first step when wafering the silicon ingots is multi-wire slicing, which is the slicing method commonly employed today.

Silicon Carbide | CoorsTek

Silicon Carbides (SiC) exhibit characteristically high hardness, wear resistance, corrosion resistance, and strength — even at high temperatures. CoorsTek has engineered a variety of silicon carbide processes and compositions which deliver properties and features optimized for specific application requirements including:

Silicon Wafer Production - MKS Inst

The final stage in silicon wafer manufacture involves chemically etching away any surface layers that may have accumulated crystal damage and contamination during sawing, grinding and lapping; followed by chemical mechanical polishing (CMP) to produce a highly reflective, scratch and damage free surface on one side of the wafer. The chemical ...
