Abstract: A circuit for controlling operation of a load. In one example, a MEMS switch is positioned in the circuit to place the load in one of a conducting state or a nonconducting state. A piezoelectric transformer provides a relatively high voltage output signal or a relatively low voltage output signal to control movement of the switch between a closed position, placing the load in the conducting state, and an open position. The high voltage output signal includes a frequency component in the resonant frequency range of the transformer. Control circuitry provides an input voltage signal to the piezoelectric transformer to provide the high voltage output signal or the low voltage output signal at the output terminals of the piezoelectric transformer.

Abstract: A method for forming smooth walled, prismatically-profiled through-wafer vias and articles formed through the method. An etch stop material is provided on a wafer, which may be a silicon wafer. A mask material is provided on the etch stop material and patterned in such a way as to lead to the formation of vias that have at least one pair of opposing side walls that run parallel to a plane in the wafer. A wet etchant, such as potassium hydroxide, is used to etch vias in the wafer. The use of a wet etchant leads to the formation of smooth side walls. This method allows an aspect ratio of height versus width of the vias of greater than 75 to 1.
