Abstract:
A method of protecting a substrate during fabrication of semiconductor, MEMS, or biotechnology devices. The method includes application of a protective thin film which typically has a thickness ranging from about 3 Å to about 1,000 Å, wherein precursor materials used to deposit the protective thin film are organic-based precursors which include at least one fluorine-comprising functional group at one end of a carbon back bone and at least one functional bonding group at the opposite end of a carbon backbone, and wherein the carbon backbone ranges in length from 4 carbons through about 12 carbons. In many applications at least a portion of the protective thin film is removed during fabrication of the devices.
Abstract:
An improved vapor-phase deposition method and apparatus for the application of multilayered films/coatings on substrates is described. The method is used to deposit multilayered coatings where the thickness of an oxide-based layer in direct contact with a substrate is controlled as a function of the chemical composition of the substrate, whereby a subsequently deposited layer bonds better to the oxide-based layer. The improved method is used to deposit multilayered coatings where an oxide-based layer is deposited directly over a substrate and a SAM organic-based layer is directly deposited over the oxide-based layer. Typically a series of alternating layers of oxide-based layer and organic-based layer are applied.

Abstract:
The present invention is related to carbon-doped metal oxide films. The carbon-doped metal oxide films provide a low coefficient of friction, for example ranging from about 0.05 to about 0.4. In addition, the carbon-doped metal oxide films applied over a silicon substrate, for example, provide anti-stiction properties, where the measured work of adhesion for a MEMS device cantilever beam coated with the carbon-doped metal oxide film is less than 10 μJ/m2. In addition, the carbon-doped metal oxide films provide unexpectedly good water vapor transmission properties. The carbon content in the carbon-doped metal oxide films ranges from about 5 atomic % to about 20 atomic %.

Abstract:
We have developed an improved vapor-phase deposition method and apparatus for the application of layers and coatings on various substrates. The method and apparatus are useful in the fabrication of biotechnologically functional devices, Bio-MEMS devices, and in the fabrication of microfluidic devices for biological applications. In one important embodiment, oxide coatings providing hydrophilicity or oxide/polyethylene glycol coatings providing hydrophilicity can be deposited by the present method, over the interior surfaces of small wells in a plastic micro-plate in order to increase the hydrophilicity of these wells. Filling these channels with a precise amount of liquid consistently can be very difficult. This prevents a water-based sample from beading up and creating bubbles, so that well can fill accurately and completely, and alleviates spillage into other wells which causes contamination.
