Reducing mems stiction by introduction of a carbon barrier
A mechanism for reducing stiction in a mems device by decreasing an amount of carbon from teos-based silicon oxide films that can accumulate on polysilicon surfaces during fabrication is provided. A carbon barrier material film is deposited between one or more polysilicon layer in a mems device and the teos-based silicon oxide layer.

Ultrananocrystalline diamond films with optimized dielectric properties for advanced rf mems capacitive switches
An efficient deposition process is provided for fabricating reliable rf mems capacitive switches with multilayer ultrananocrystalline (uncd) films for more rapid recovery, charging and discharging that is effective for more than a billion cycles of operation. Significantly, the deposition process is compatible for integration with cmos electronics and thereby can provide monolithically integrated rf mems capacitive switches for use with cmos electronic devices, such as for insertion into phase array antennas for radars and other rf communication systems..
