    摘要: A thin gas distribution plate is provided, consistent with requirements for mechanical rigidity and strength. The gas distribution plate has sufficiently low mass to permit rapid heating to an equilibrium temperature as determined by radiated heat loss. The gas distribution plate has a thinner central cross-section, optionally including smaller diameter apertures formed therethrough; and has a thicker circumferential cross-section, optionally having larger apertures formed therethrough, to thereby promote even gas distribution across the surface of the wafer, while mitigating or eliminating entirely the first wafer effect.

    摘要: An improved low-volume gas distribution assembly for a chemical downstream etch tool includes a focusing collar positioned within a process chamber and having a depending shroud in close proximity to a wafer chuck. An apertured gas delivery conduit rests on channels formed in slanted sides of a central tube of the focusing collar. The apertures in the gas delivery conduit are patterned and dimensioned to provide substantially uniform distribution of a process gas over the upper surface of the workpiece. The central tube is sealed with a cover plate and the process chamber is covered with a chamber lid.

    摘要: A process for producing a strip removes photoresist and extraneous deposits of polymer residue on the top surface and sidewalls of a post-metal etch wafer. The photoresist and residue are processed simultaneously by a chemical mechanism comprising reactive species derived from a microwave-excited fluorine-containing downstream gas, and a physical mechanism comprising ion bombardment that results from a radio frequency excited plasma and accompanying wafer self bias. A vacuum pump draws stripped photoresist and residues from the surface of the wafer and exhausts them from the chamber.

    摘要: Embodiments of a cluster tool, processing chamber and method for processing a film stack are provided. In one embodiment, a method for in-situ etching of silicon and metal layers of a film stack is provided that includes the steps of etching an upper metal layer of the film stack in a processing chamber to expose a portion of an underlying silicon layer, and etching a trench in the silicon layer without removing the substrate from the processing chamber. The invention is particularly useful for thin film transistor fabrication for flat panel displays.

    摘要: A method of etching a dielectric layer formed on a substrate including a sequence of processing cycles, wherein each cycle comprises steps of depositing an inactive polymeric film, activating the film to etch the structure, and removing the film is disclosed. In one embodiment, the method uses a fluorocarbon gas to form the polymeric film and a substrate bias to activate such film.
