    摘要: A magnetic field generator for producing a magnetic field that accelerates plasma formation is placed proximate a reaction chamber of semiconductor substrate processing system. The magnetic field generator has four main magnetic coil sections for producing a magnetic field nearly parallel to the top surface of a support pedestal in the reaction chamber and four sub-magnetic coil sections placed generally coaxially with the main magnetic coil sections to produce a magnetic field of the direction opposite of that of the magnetic field produced with the main magnetic coil sections. In the magnetic field generator, magnetic fields of opposite polarities are superimposed on each other when electric currents of opposite directions are applied to the main and sub-magnetic coil sections.

    摘要: A method for etching an organic anti-reflective coating (OARC) using a halogen-free gas chemistry is disclosed. The organic anti-reflective coating (OARC) is etched using a gas mixture comprising at least one of a hydrocarbon-containing gas and an oxygen-containing gas. The method provides high etch selectivity for the organic anti-reflective coating (OARC) over metal layers (e.g., copper (Cu), aluminum (Al), and the like) or dielectric layers (silicon dioxide (SiO2), and the like).

    摘要: A method and apparatus for processing a workpiece in a chamber by providing an asymmetric flow of process gas and processing the workpiece with the process gas. The asymmetric flow counteracts a non-uniform distribution of reactive species in the chamber. The asymmetric flow can be accomplished by introducing the process gas through a plurality of gas nozzles that communicate through a side wall of the chamber proximate a pump port while pumping gas with a pump coupled to the pump port. The inventive method can be used with a conventional processing chamber by only opening the gas nozzles closest to the pump and blocking any other gas nozzles. Alternatively, the method can be implemented in a processing chamber having gas nozzles located only proximate the pump port.

    摘要: A method of forming an interconnect structure (e.g., copper interconnect structure, and the like) on a semiconductor substrate. The interconnect structure is formed by depositing within trenches and openings formed in an inter-metal dielectric (IMD) layer a barrier layer and a conductive material. Thereafter, the interconnect structure is planarized using a two-step process whereby excess conductive material on the IMD material is removed during the first step using a chemical mechanical polishing (CMD) process. In the second step the barrier layer is removed using a plasma etch process. The barrier layer is removed using a gas mixture including a halogen-containing gas.
