摘要： A field effect transistor (10) for chemical sensing by measuring a change in a surface potential of a gate electrode (48) due to exposure to a fluid has a semiconductor substrate (12) with a trench (18,20). The trench has a first sidewall (30) and a second sidewall (32) disposed opposite the first sidewall to provide a fluid gap (50) for the fluid to be sensed. The gate electrode is disposed overlying the first sidewall of the trench, and a source region (54) and a drain region (56) are disposed in the second sidewall of the trench. A channel region (52) is disposed between the source and drain regions, and the gate electrode is disposed opposite the first channel region across the fluid gap. A heater (26) for regulating the temperature of the gate electrode is disposed in the first sidewall of the trench.

摘要： A micro-electromechanical (MEM) device has a folded tether spring in which each fold of the spring is surrounded by a rigidly fixed inner structure and outer structure. The fixed inner structure increases restoring force of the spring. The rigidly fixed inner and outer structures each have a major surface that include a plurality of notches of fixed width relative to a distance between the major surface and the spring. Additionally in one form extensions from the major surface of the rigidly fixed inner and outer structures are provided at distal ends thereof to make initial contact with the spring. The notches of the MEM device both reduce surface area contact with the spring and wick moisture away from the spring to minimize stiction.
