   Abstract:
   We describe a method for estimating the Young's modulus of thin-film gold deposited on the poly2 layer in the MUMPs process is described. An optical detection system employing position sensitive detectors (PSD) is built to measure the bimetallic (gold/poly2) cantilever deflection with increasing temperature. Measured cantilever deflections are compared to finite element simulations performed with MEMCAD [trademark] which show an excellent match for a Young's modulus of 78GPa and a Poisson's ratio of 0.35.
