Abstract:
A microelectromechanical structure is formed by depositing sacrificial and structural material over a substrate to form a structural layer on a component electrically attached with the substrate. The galvanic potential of the structural layer is greater than the galvanic potential of the component. At least a portion of the structural material is covered with a protective material that has a galvanic potential less than or equal to the galvanic potential of the component. The sacrificial material is removed with a release solution. At least one of the protective material and release solution is surfactanated, the surfactant functionalizing a surface of the component.
