    摘要: Gas distribution systems for deposition processes and methods of using the same. A substrate support member holding a substrate is disposed in a processing chamber. A plurality of first and second gas nozzles is connected to a gas distribution ring disposed in the processing chamber. The first gas nozzles provide a first reactant gas and include at least first and second outlet apertures. The second gas nozzles provide a second reactant gas and include third outlet apertures. The first outlet aperture is larger than the second outlet aperture, such that the first gas nozzle with the first outlet aperture creates an increased gas flow adjacent to a determined portion of the substrate to increase deposition from the first reactant gas on the determined portion of the substrate.

    摘要: This invention relates to a method of fabrication used for semiconductor integrated circuit devices, and more specifically, to improve the photolithography processing window of a multi-layered dual damascene process by using a dielectric anti-reflective coating, DARC, comprised of multiple layers of silicon oxynitride, SiON, with varying k, dielectric constant values and thickness, to reduce reflectivity and improve light absorption. By varying both the thickness and the dielectric constant of the layers, the optical properties of light absorption, refractive indices, and light reflection are optimized.

    摘要: A device includes a semiconductor substrate, which has a front side and a backside. A photo-sensitive device is disposed on the front side of the semiconductor substrate. A first and a second grid line are parallel to each other, and are disposed on the backside of, and overlying, the semiconductor substrate. A stacked layer includes an adhesion layer, a metal layer over the adhesion layer, and a high-refractive index layer over the metal layer. The adhesion layer, the metal layer, and the high-refractive index layer are substantially conformal, and extend on top surfaces and sidewalls of the first and the second grid lines.

    摘要: A shallow trench isolation (STI) structure for semiconductor devices is formed using a deposited silicon layer formed over a polish stop layer formed over an oxide formed on a substrate. The polish stop layer may be nitride. An opening is formed extending through the deposited silicon layer and the nitride and oxide layers and extending into the substrate. A deposited oxide is formed filling the opening and extending over the top surface of deposited silicon layer. A chemical mechanical polishing operation polishes the deposited silicon layer at a rate faster than the deposited oxide layer to produce an STI with a convex portion extending above the nitride layer. Dishing problems are avoided and the structure may be subsequently planarized.

    摘要: A method and means for detection of oxidizing contamination in acid etching baths employed to etch silicon oxide layers from silicon substrates employed in silicon integrated circuit microelectronics fabrications. There is provided a silicon substrate having within a doped region formed employing ion implantation. The silicon substrate is immersed within a buffered oxide etch (BOE) acid bath, wherein the presence of an oxidizing contaminant correlates with an increase in the resistance of the doped region upon the removal of any silicon oxide layer on the silicon surface.
