The application of precision grinding for the formation of a silicon diaphragm is investigated. The test structures involved 26 mm diam diaphragms with thicknesses in the range of 25150 μm. When grinding is performed without supporting the diaphragm, bending occurs due to nonuniform removal of the silicon material over the diaphragm region.

Typical Tolerances of Manufacturing Processes . In the past, one of the traditional weaknesses with graduating mechanical design engineers is their inability to select tolerances. Most students were reasonably proficient using one or more CAD packages and could produce drawings which were pretty good (given their limited experience levels).

This process is preferred in many cases because it is faster and less costly than the newer chemical or plasma etching processes that have been recently developed. However, it does have the disadvantages of applying mechanical stress and heat during the grinding process and of causing scratches on the backside of the wafer.

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 nonuniform 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.
