WebThe residual stress of the corrugated diaphragm seriously affects the yield, service life and reliability of the cavity type MEMS device. Therefore, this paper studies the reduction of residual stress by optimizing the structural parameters of the corrugated diaphragm applied to MEMS devices. The test results are in agreement with the simulation results, … WebJul 1, 2002 · The diaphragm deflections, caused by relaxation of the residual stress in a patterned thin film residing on top, were measured using a Twyman–Green laser interferometer. The first diaphragm used was a Si 3 N 4 (top)/SiO 2 /Si composite diaphragm and the second a 0.5-μm-thick Si 3 N 4 membrane.
