Bulk silicon etching techniques, used to selectively remove silicon from substrates, have been broadly applied in the fabrication of micromachined sensors, actuators, and structures. Despite the more recent emergence of higher resolution, surface-mic

Devices and circuits capable of high-voltage operation are necessary for the actuation of micromachined electrostatic structures that require high voltages (20–100 V). These high-voltage devices have traditionally been fabricated using specialized
