    摘要: A substrate processing system includes a housing defining a chamber for forming a film on the substrate surface of a substrate disposed within the chamber. The system includes a first plurality of nozzles that extend into the chamber for injecting a first chemical at a first distance from a periphery of the substrate surface, and a second plurality of nozzles that extend into the chamber for injecting a second chemical at a second distance from the periphery of the substrate surface. The second distance is substantially equal to or smaller than the first distance. In one embodiment, the first chemical contains a dielectric material and the second chemical contains dopant species which react with the first chemical to deposit a doped dielectric material on the substrate. Injecting the dopant species closer to the substrate surface than previously done ensures that the dopant species are distributed substantially uniformly over the substrate surface and the deposition of a stable doped dielectric layer.

    摘要: The present invention provides an HDP-CVD tool using simultaneous deposition and sputtering of doped and undoped silicon dioxide capable of excellent gap fill and blanket film deposition on wafers having sub 0.5 micron feature sizes having aspect ratios higher than 1.2:1. The system of the present invention includes: a dual RF zone inductively coupled plasma source configuration capable of producing radially tunable ion currents across the wafer; a dual zone gas distribution system to provide uniform deposition properties across the wafer surface; temperature controlled surfaces to improve film adhesion and to control extraneous particle generation; a symmetrically shaped turbomolecular pumped chamber body to eliminate gas flow or plasma ground azimuthal asymmetries; a dual helium cooling zone electrostatic chuck to provide and maintain uniform wafer temperature during processing; an all ceramic/aluminum alloy chamber construction to eliminate chamber consumables; and a remote fluorine based plasma chamber cleaning system for high chamber cleaning rate without chuck cover plates.
