Abstract
From a silicon-on-insulator (SOI) wafer, a microtranslation table with scratch-drive actuator (SDA) has been fabricated. The device Si layer of SOI wafer is etched to form the plate of SDA, which is partially connected to the handle Si substrate by the SiO 2 layer. Dicing the handle Si substrate, a microtranslation table with the SDA array has been fabricated. Placing the microtranslation table upside down on the other Si substrate on which a thin conductive film is patterned for the electrical connection, the microtranslation table is moved by the SDA without carrying a metal wire. The moving velocity of 45.5 μm/s has been obtained by applying the voltage of 120 V at the operating frequency of 500 Hz.
