In many cases the SOI wafers provide better process control and better performance. However, SOI MEMS technology has some limitations such as, the gap between the released mechanical structure and the substrate cannot be freely adjusted, but is limited to the thickness of the buried thermal oxide used as a sacrificial layer.
With its balance between cost and material performance, Silicon is one of many choices for MEMs, power electronics, and biosensors, each with their own industry needs. Saint-Gobain Surface Conditioning has recently re-engineered the standard Silicon polishing process to help our partners with capacity, evolving surface needs, and cost.

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 .
The grinding process is employed to thin the silicon wafer rapidly using the GRIND-X GNX200 machine until the deepest trenches expose. The grinding rate is about 100 µm min −1. Then, the polishing process is used to remove grinding marks and smooth the silicon surface. The polishing step sacrifices about 5 µm thick silicon.
For example, a particular process known as in-process electrolytic dressing, (ELID) is employed in a grinding process to mirror-grind silicon wafers [2,40]. Electrolytic dressing exposes the abrasive grains and thus allows a grinding process to take place. Grinding replaces a lapping process with much improved productivity and accuracy.

Inside diameter grinding, also called as internal grinding, is used for grinding the inner diameter of tubular object. Workpiece or object will have already drilled hole and internal grinding process will be performed to finish the inner surface of workpiece with the help of small grinding wheel rotating at higher revolution per minute.
The process is purely physical and does not depend on parameters such as the temperature or wafer doping con-centration. Precision grinding of silicon proceeds in two stages: coarse grinding followed by ﬁne grinding. During the coarse grinding stage, the wafer and grind wheel rotate at 200–250 rpm, the removal rate of silicon is about 250
