The thickness variation and the breakage of silicon diaphragms are mainly dictated by the grinding process, since grinding forces may deflect the diaphragm leading to non-uniform material removal within the cavity area. The thickness variation is largest at the centre of the cavity and decreases towards the edge of the cavity.

The process frequency can act as an actuator on any part of the MEMS. Depending on the geometry and materials of the MEMS under consideration, it is necessary to analyze to likelihood of problems. If one of the eigenfrequencies of the MEMS or the WLTFP is (very) close to the bonding frequency, it may start to resonate.

All commercially available grinding systems use a two-step process including a coarse grinding (with thinning rates of about 5 µm/sec) and a subsequent fine grinding (thinning rate ≤1µm/sec). The second step of the process is necessary to remove most of the damage layer created by the coarse grinding step and reduce surface roughness.

Coolant is used in centerless grinding to not only keep the grinding wheel cool, but also remove heat from the zone where the workpiece contacts the grinding wheel. Centerless grinding requires the use of correctly pressurized coolant to overcome the air barrier created between the grinding wheel and workpiece during the grinding process.
