摘要: Surface micromachined, polysilicon fuse and weld microstructures are modeled, fabricated, characterized. The current required to cut the thin, 2000 AA is 30 mA, compared 80 mA for a 2 mu m-thick fuse. For large currents, simple model shows that time inversely proportional square of current. An aluminum microbridge used form robust weld, connecting two structures. surface tension molten Al produces force approximately 15 M, which about 100 times larger than electrostatic comb drive forces. A series pulses melt without destroying joint. >
