Grinding of silicon wafers: A review from historical,

01/10/2008· This review paper discusses historical perspectives on grinding of silicon wafers, impacts of wafer size progression on applications of grinding in silicon wafer manufacturing, and interrelationships between grinding and two other silicon machining processes (slicing and polishing). It is organized into six sections. Following this introduction section, Section 2 describes extension of,Grinding plant - Fives in Cement | Minerals,Ores and industrial minerals: GBFS, silicon metal, ilmenite slag, calcium carbonate, aggregates, phosphates… Solid fuels: coal, petro coke; Key references.

High speed grinding of silicon nitride with resin bond,

This paper reports on the high speed grinding performance of silicon nitride using resin bond diamond wheels. The investigation focuses on the effect of wheel speeds on material removal mechanisms and ground surface quality. With a wheel of grit size 160 μm, the effect of wheel speed on the ground surface quality was insignificant because brittle fracture was prevalent during grinding.
