Read OnChemical-mechanical polishing is a key technology in the production and processing of silicon wafers and other semiconductor materials. CMP is one of the technologies that make the realization of state-of-the-art microelectronic devices and micro-electro-mechanical systems (MEMS) possible in the first place.
Read OnPressure controls the velocity of the fluid; the flow rate and temperature control the rate of heat transfer into the fluid. The direction of the flow allows the fluid to remove the air-barrier that travels with the wheel. Many researchers have studied the role of grinding fluids in preventing thermal damage to the workpiece over the past 30 years.
