Abstract:
An IPVD source assembly for supplying and ionizing material for coating a semiconductor wafer, the assembly comprising:a housing assembly having: an external ground connector, an external target power connector, an RF power source connector, external cooling fluid recirculating ports, an internal target power terminal, at least two internal RF connectors, a plurality of internal cooling fluid ports, and electrically non-conductive support structure; an RF coil assembly removably secured to the housing and including: a three-dimensional coil removably connected across the internal RF connectors, and the coil having a cooling passage therethrough removably connected across at least two of the internal cooling fluid ports; an annular permanent magnet assembly removably secured to the housing and surrounding the RF coil assembly; a window assembly removably secured to the to either the housing or the coil assembly, the window assembly including a substantially flat dielectric window; an annular target assembly removably connected to the housing and forming a vacuum tight seal with the window when so connected, the target assembly including an annular expendable sputtering target configured to form a liquid tight cooling passage for the target that is removably connected across at least two of the internal cooling ports, the target assembly having an electrical connector removably connected to the internal target power terminal of the housing; and vacuum tight seal structure between the target assembly and the wall of a vacuum processing chamber when the IPVD source assembly is connected thereto.
