Abstract. An analysis has been conducted to determine biaxial initial
stresses in gold bilayer switches processed with sacrificial photoresists.
The electroplated gold layer was characterized by wafer curvature
technique and an analytical method based on the cantilever deflection
method is investigated numerically and experimentally to characterized the
evaporated gold seed layer. |
