摘要： The present invention provides a method of fabricating a thermally stable polysilicon/high-k dielectric film stack utilizing a deposition method wherein Si-containing precursor gas which includes silicon and hydrogen is diluted with an inert gas such as He so as to significantly reduce the hydrogen content in the resultant polysilicon film. Semiconductor structures such as field effect transistors (FETs) and capacitors which include at least the thermally stable polysilicon/high-k dielectric film stack are also provided herein.

摘要： Etching equipment and methods are disclosed herein for more efficient etching of sacrificial material from between permanent MEMS structures. An etching head includes an elongate etchant inlet structure, which may be slot-shaped or an elongate distribution of inlet holes. A substrate is supported in proximity to the etching head in a manner that defines a flow path substantially parallel to the substrate face, and permits relative motion for the etching head to scan across the substrate.

摘要： Methods, devices, and systems provide MEMS devices exhibiting at least one of reduced stiction, reduced hydrophilicity, or reduced variability of certain electrical characteristics using MEMS devices treated with water vapor. The treatment is believed to form one or more passivated surfaces on the interior and/or exterior of the MEMS devices. Relatively gentle temperature and pressure conditions ensure modification of surface chemistry without excessive water absorption after removal of sacrificial material to release the MEMS devices.
