  • Patent number: 8058156
    Abstract: A plasma immersion ion implantation process for implanting a selected species at a desired ion implantation depth profile in a workpiece is carried out in a reactor chamber having a set of plural parallel ion shower grids that divide the chamber into an upper ion generation region and a lower process region, each of the ion shower grids having plural orifices in mutual registration from grid to grid, the plural orifices oriented in a non-parallel direction relative to a surface plane of the respective ion shower grid. The process includes placing a workpiece in the process region, the workpiece having a workpiece surface generally facing the surface plane of the closest one of the plural ion shower grids, and furnishing the selected species into the ion generation region. The process further includes evacuating the process region, and applying plasma source power to generate a plasma of the selected species in the ion generation region.

  • Publication number: 20110248182
    Abstract: An ion implanting apparatus is provided, which can accurately measure a quantity of atoms that are implanted. The ion implanting apparatus according to the present invention has an object to be measured, and the object to be measured is arranged in an irradiating range in which ions are irradiated. When atoms are implanted into an object to be processed by irradiating ions of a processing gas and neutralized particles thereof, the object to be measured is heated through the irradiation with the processing gas ions and the neutralized particles. A control unit determines a quantity of the atoms that are implanted into the object to be processed from the temperature of the object to be measured.

  • Patent number: 8029305
    Abstract: Connection resistance (Rc) resulting from the resilient deformation of a lock arm (26) is produced in the process of connecting two housings (10, 20), and connection resistance (Rb) resulting from a resilient restoring force of a grommet (30) held in contact with a panel (P) is produced with the two housings (10, 20) properly connected. In the process of connecting the two housings (10, 20), the connection resistance (Rb) resulting from the resilient restoring force of the grommet (30) increases after the lock arm (26) is resiliently restored.

  • Publication number: 20110212272
    Abstract: A magnetic recording medium having a high magnetic pattern contrast is manufactured. By changing an acceleration voltage that accelerates ions in a process gas, depths (peak depths D0 and D1) from a magnetic layer 44, at which an injection amount of a target element is the maximum, can be made with set depths even if a film thickness of an ion permeation portion 48, which is a thin film portion of a resist 49, decreases. Since the set depths are achieved for the peak depths D0 and D1, a portion to be processed 43 of the magnetic film 44 is made non-magnetized from a top surface to a bottom surface, and a magnetic portion is separated; thus, the magnetic recording medium with a high magnetic pattern contrast can be obtained.

  • Publication number: 20110192349
    Abstract: A plurality of RF power signals have the same RF frequency as a reference RF signal and are coupled to respective RF connection points on an electrode of a plasma chamber. At least three of the RF connection points are not collinear. At least two of the RF power signals have time-varying phase offsets relative to the reference RF signal that are distinct functions of time. Such time-varying phase offsets can produce a spatial distribution of plasma in the plasma chamber having better time-averaged uniformity than the uniformity of the spatial distribution at any instant in time.
