The hollow gas deposition volume may include a volume reducing lower portion. An aerodynamically shaped substrate support chuck is disposed inside gas deposition chamber with a substrate support surface positioned in the constant volume cylindrical middle portion. The volume expanding top portion reduces gas flow velocity between gas input ports and the substrate support surface.

Method and apparatus for producing high efficiency fibrous media incorporating discontinuous sub-micron diameter fibers, and web media formed thereby

A composite filtration medium web of fibers containing a controlled dispersion of a mixture of sub-micron and greater than sub-micron diameter polymeric fibers is described. The filtration medium is made by a two dimensional array of cells, each of which produces a single high velocity two-phase solids-gas jet of discontinuous fibers entrained in air. The cells are arranged so that the individual jets are induced to collide in flight with neighboring jets in their region of fiber formation, to cause the individual nascent fibers of adjacent jets to deform and become entangled with and partially wrap around each other at high velocity and in a localized fine scale manner before they have had an opportunity to cool to a relatively rigid state. The cells are individually adjusted to control the mean diameters, lengths and trajectories of the fibers they produce. Certain cells are adjusted to generate a significant percentage of fibers having diameters less than one micron diameter, and which are relatively shorter in length and certain other cells are adjusted to generate a significant percentage of structure-forming reinforcing fibers having diameters greater than one micron diameter which are relatively longer in length. By employing appropriate close positioning and orientation of the cells in the array, the sub-micron fibers are caused to promptly entangle with and partially wrap around the larger reinforcing fibers. The larger fibers thereby trap and immobilize the sub-micron diameter fibers in the region of formation, to minimize the tendency of sub-micron diameter fibers to clump, agglomerate, or rope together in flight. Also, the larger fibers in flight are made to form a protective curtain to prevent the sub-micron fibers from being carried off by stray air currents.

Barrier first method for single damascene trench applications

Methods for forming a diffusion barrier on low aspect features of an integrated circuit include at least three operations. The first operation deposits a barrier material and simultaneously etches a portion of an underlying metal at the bottoms of recessed features of the integrated circuit. The second operation deposits barrier material to provide some minimal coverage over the bottoms of the recessed features. The third operation deposits a metal conductive layer. Controlled etching is used to selectively remove barrier material from the bottom of the recessed features, either completely or partially, thus reducing the resistance of subsequently formed metal interconnects.

Method and apparatus for treatment of congestive heart failure by improving perfusion of the kidney by infusion of a vasodilator

A method for treating congestive heart failure (CHF) has been developed that restores kidney renal functions by artificial vasodilation of at least one kidney. A vasodilator drug is locally delivered to the kidney via a kidney perfusion catheter. The drug can be mixed with the patient's blood, saline or other suitable solvent and the mixture directly applied to the kidney through the catheter. The restoration of kidney function assists the heart by removing excess fluid, urine and toxin from the patient, and by normalizing the patient's renin-angiotensin system and other neurohormonal substances. The method is applicable to treat chronic and acute CHF.
