摘要:
A substrate processing system includes a thermal processor or a plasma generator adjacent to a processing chamber. A first processing gas enters the thermal processor or plasma generator. The first processing gas then flows directly through a showerhead into the processing chamber. A second processing gas flows through a second flow path through the showerhead. The first and second processing gases are mixed below the showerhead and a layer of material is deposited on a substrate under the showerhead.
摘要:
A silicon dioxide layer is deposited onto a substrate using a process gas comprising BDEAS and an oxygen-containing gas such as ozone. The silicon dioxide layer can be part of an etch-resistant stack that includes a resist layer. In another version, the silicon dioxide layer is deposited into through holes to form an oxide liner for through-silicon vias.

Embodiments described herein provide a method of processing a substrate. The method includes depositing an interface adhesion layer between a conductive material and a dielectric material such that the interface adhesion layer provides increased adhesion between the conductive material and the dielectric material. In one embodiment a method for processing a substrate is provided. The method comprises depositing an interface adhesion layer on a substrate comprising a conductive material, exposing the interface adhesion layer to a nitrogen containing plasma, and depositing a dielectric layer on the interface adhesion layer after exposing the interface adhesion layer to the nitrogen containing plasma.

摘要:
A method for the removal of copper oxide from a copper and dielectric containing structure of a semiconductor chip is provided. The copper and dielectric containing structure may be planarized by chemical mechanical planarization (CMP) and treated by the method to remove copper oxide and CMP residues. Annealing in a hydrogen (H2) gas and ultraviolet (UV) environment removes copper oxide, and a pulsed ammonia plasma removes CMP residues.

摘要:
Stress of a silicon nitride layer may be enhanced by deposition at higher temperatures. Employing an apparatus that allows heating of a substrate to substantially greater than 400° C. (for example a heater made from ceramic rather than aluminum), the silicon nitride film as-deposited may exhibit enhanced stress allowing for improved performance of the underlying MOS transistor device. In accordance with alternative embodiments, a deposited silicon nitride film is exposed to curing with ultraviolet (UV) radiation at an elevated temperature, thereby helping remove hydrogen from the film and increasing film stress. In accordance with still other embodiments, a silicon nitride film is formed utilizing an integrated process employing a number of deposition/curing cycles to preserve integrity of the film at the sharp corner of the underlying raised feature. Adhesion between successive layers may be promoted by inclusion of a post-UV cure plasma treatment in each cycle.

摘要:
A layer of silicon nitride having a thickness from 0.5 nanometers to 2.4 nanometers is deposited on a substrate. A plasma nitridation process is carried out on the layer. These steps are repeated for a plurality of additional layers of silicon nitride, until a predetermined thickness is attained. Such steps can be used to provide a multilayer silicon nitride dielectric formed on a substrate having an upper surface of dielectric material with Cu and other conductors embedded within, and a plurality of steps. The multilayer silicon nitride dielectric has a plurality of individual layers each having a thickness from 0.5 nanometers to 2.4 nanometers, and the multilayer silicon nitride dielectric conformally covers the steps of the substrate with a conformality of at least seventy percent. A multilayer silicon nitride dielectric, and a multilevel back end of line interconnect wiring structure using same, are also provided.
