Abstract: A deposition system includes a process chamber for conducting an ALD process to deposit layers on a substrate. In one embodiment, instead of varying the gas flux on a substrate in the chamber by controlling the flow of gas upstream of the process chamber, the gas flux on the substrate is controlled by controlling the conductance between the process chamber and a lower pressure volume outside the process chamber. The flux of the gas on the substrate varies inversely with the chamber conductance, such that the flux of the gas on the substrate increases when the conductance decreases. Various methods of performing an ALD process by controlling the conductance are disclosed as well as various structures for controlling the conductance.

Sprinkler water contacts and dissolves the solid polymeric products, carrying water soluble polymer into the wheel track.

Abstract: A heterogeneous mixture produced by blending aliphatic or cyclic organic compounds with carboxylic acids of chemical structure R—COOH and applied to soils in a manner to produce high levels of dust and erosion control, and soil stabilization. Alternatively, a heterogeneous mixture may be produced by blending aliphatic or cyclic organic compounds with polyolefins of chemical structure CnH2n or R—C2nH3n, and applied to soils in a manner to produce high levels of dust control and soil stabilization. The aliphatic and cyclic compounds act as plasticizers and carriers for the carboxylic acids or polyolefin compounds. When applied to soil the carrier provides a mechanism for the carboxylic acid or polyolefin to penetrate the soil and also acts as a dust suppressing weighting agent. The plasticized carboxylic acid and/or polyolefin provides a durable, reworkable binder that associates small particulates while stabilizing soil and aggregate.

Abstract: A method for depositing an anti-stiction coating on a MEMS device comprises reacting the vapor of an amino-functionalized silane precursor with a silicon surface of the MEMS device in a vacuum chamber. The method can further comprise cleaning the silicon surface of the MEMS device to form a clean hydroxylated silicon surface prior to reacting the precursor vapor with the silicon surface. The amino-functionalized silane precursor comprises at least one silicon atom, at least one reactive amino (or imine) pendant, and at least one hydrophobic pendant. The amino-functionalized silane precursor is highly reactive with the silicon surface, thereby eliminating the need for a post-process anneal step and enabling the reaction to occur at low pressure. Such vapor-phase deposition of the amino-functionalized silane coating provides a uniform surface morphology and strong adhesion to the silicon surface.

Abstract: A chalcogen film is applied to an acute tip of a glass fiber and the acute tip is held in physical contact with a metal layer so as to induce diffusional reaction for generation of a metal chalcogenide nano-particle or nano-particles at the acute tip. In the case where the chalcogen film is directly applied to the acute tip, the generated nano-particle or nano-particles are transferred from the acute tip to a corresponding part of the metal layer. When a silane-adsorbed film is pre-formed on the acute tip before application of the chalcogen film, the generated nano-particle or nano-particles are fixed to the acute tip. The nano-particles are several to tens in number with very narrow distribution of particle size. Since particle size and fixed position of the nano-particle or nano-particles can be controlled with high freedom, the nano-particle or nano-particles are useful as a light-emitting or photo-detecting element.
