    摘要: A micromachined multi-layered microbellows-style actuator capable of delivering larger deflections compared to a single layered flat membrane of comparable size. Anchor structures are disclosed that improve the strength of the microbellows membrane. A characterization apparatus is used to measure microbellows membrane performance. Thermopneumatic actuators having a resistive heater chip are also disclosed. The microbellows membrane is manufactured by alternating deposition of structural layers and sacrificial layers on a substrate. The structural layers can be made of silicon nitride and the sacrificial layers can be made of polysilicon. The substrate is etched from the back to form an opening exposing the sacrificial layers, and then the membrane is released by etching away the sacrificial layers.

    摘要: An anti stiction structure for cantilever formation technique. In one embodiment, the polymer cantilever is prevented from sticking to the substrate by at amortized stick layer on the substrate during formation that is later removed as a sacrificial layer. In another embodiment, the cantilever includes downwardly extending legs.
