Abstract:

Numerous studies suggest that the current popular designs of coronary stents are functionally equivalent and suffer a 16 to 22 percent rate of restenosis. Although the use of coronary stents is growing, the benefits of their use remain controversial in certain clinical situations or indications due to their potential complications. The application of gas cluster ion beam (GCIB) surface modification such as smoothing or cleaning appears to reduce these complications and lead to genuine cost savings and an improvement in patient quality of life. The present invention is directed to the use of GCIB surface modification to overcome prior problems of thrombosis and restenosis. The atomic level surface smoothing of stents utilizing GCIB substantially reduces undesirable surface micro-roughness in medical coronary stents.

US Classification:

709231, 709219

Abstract:

Abstract:

A gas cluster ion beam (GCIB) processing system using multiple nozzles for forming and emitting at least one GCIB and methods of operating thereof are described. The GCIB processing system may be configured to treat a substrate, including, but not limited to, doping, growing, depositing, etching, smoothing, amorphizing, or modifying a layer thereupon. Furthermore, the GCIB processing system may be operated to produce a first GCIB and a second GCIB, and to irradiate a substrate simultaneously and/or sequentially with the first GCIB and second GCIB.

International Classification:

F21V 13/00

US Classification:

362245, 362235, 36224902

Abstract:

Disclosed exemplary solid state light fixtures use optical cavities to combine or integrate light from LEDs or the like. In such a fixture, the cavity is formed by a light transmissive structure having a volume, and a diffuse reflector that covers a contoured portion of the structure. A circuit board has flexible tabs mounting the light emitters. A heat sink member supports the circuit board and is contoured relative to the shape of the light transmissive structure so that the tabs bend and the emitters press against a sufficiently rigid periphery of the light transmissive structure. TIM may be compressed between the heat sink member and the opposite surface of each tab. Various contours/angles of the periphery of the light transmissive structure and the mating portion of the heat sink member may be used.

Abstract:

Disclosed are methods of operation to grow, modify, deposit, or dope a layer upon a substrate using a multi-nozzle and skimmer assembly for introducing a process gas mixture, or multiple process gases mixtures, in a gas cluster ion beam (GCIB) system. Also disclosed is a method of forming a shallow trench isolation (STI) structure on a substrate, for example, an SiOSTI structure, using a multiple nozzle system with two separate gas supplies, for example providing a silicon-containing gas and an oxygen-containing gas.

US Classification:

2504923, 250423 R, 250427

Abstract:

A processing system is provided for irradiating a substrate with a gas cluster ion beam (GCIB). The system includes a nozzle for forming and emitting gas cluster beams through a nozzle outlet, and a stagnation chamber that is located upstream of and adjacent the nozzle. The stagnation chamber has an inlet, and the nozzle is configured to direct a single gas cluster beam toward the substrate. An ionizer is positioned downstream of the outlet and is configured to ionize the gas cluster beam to form the GCIB. The system also includes a gas supply that is in fluid communication with the inlet of the stagnation chamber, and which includes a gas source and a valve located between the gas source and the nozzle for controlling flow of a gas between the gas source and the nozzle.

Abstract:

Disclosed is a multi-nozzle and skimmer assembly for introducing a process gas mixture, or multiple process gases mixtures, in a gas cluster ion beam (GCIB) system, and associated methods of operation to grow, modify, deposit, or dope a layer upon a substrate. The multiple nozzle and skimmer assembly includes at least two nozzles arranged in mutual close proximity to at least partially coalesce the gas cluster beams emitted therefrom into a single gas cluster beam and/or angled to converge each beam toward a single intersecting point to form a set of intersecting gas cluster beams, and to direct the single and/or intersecting gas cluster beam into a gas skimmer.
