  • Patent number: 9023720
    Abstract: After formation of a silicon Fin part on a silicon substrate, a thin film including an impurity atom which becomes a donor or an acceptor is formed so that a thickness of the thin film formed on the surface of an upper flat portion of the silicon Fin part becomes large relative to a thickness of the thin film formed to the surface of side wall portions of the silicon Fin part. A first diagonal ion implantation from a diagonal upper direction to the thin film is performed and subsequently a second diagonal ion implantation is performed from an opposite diagonal upper direction to the thin film. Recoiling of the impurity atom from the inside of the thin film to the inside of the side wall portions and to the inside of the upper flat portion is realized by performing the first and second diagonal ion implantations.

  • Patent number: 7597531
    Abstract: Embodiments of the invention are directed to a method of controlling a mover device The method includes generating a moving force from a moving force generating unit to move a processing base with respect to a movable base, thereby moving the processing base with respect to a fixed base as a result of the movement of the processing base with respect to the movable base; moving the movable base on the fixed base in the opposite direction to the moving direction of the processing base by virtue of a reaction force caused by the moving force generated from the moving force generating unit to move the processing base, so that the movable base moves in the opposite direction to the moving direction of the processing base on the fixed base. The method further includes controlling the moving velocity of the processing base with respect to the fixed base.

  • Patent number: 7315034
    Abstract: In an irradiation system with an ion beam/charged particle beam having an energy filter, the energy filter is formed by deflection electrodes and a deflection magnet which can be switchingly used. The deflection magnet has a general window-frame shape and is formed with a hollow portion at its center. The deflection electrodes are installed, along with suppression electrodes, in a vacuum chamber arranged in the hollow portion of the deflection magnet. The deflection electrodes are installed with respect to the deflection magnet such that a deflection trajectory of a beam caused by a magnetic field and a deflection trajectory of a beam caused by an electric field overlap each other. Since the deflection electrodes and the deflection magnet can be switchingly used, the system can deal with a wider range of beam conditions and thus is widely usable.

  • Patent number: 7304319
    Abstract: A charge compensation device according to this invention is for suppressing charging of a wafer when the wafer is irradiated with a beam from a beam generation source unit. The charge compensation device comprises at least one first arc chamber having at least one first extraction hole and a second arc chamber having at least one second extraction hole faced on the reciprocal swinging beam of the predetermined scan range. A first arc voltage is applied to the first arc chamber to generate first plasma in the first arc chamber. The generated first plasma is extracted from the first arc chamber and introduced into the second arc chamber. Second plasma is produced in the second arc chamber, and second extracted plasma from the second arc chamber forms a plasma bridge between the second extraction hole and the reciprocal swinging beam.

  • Patent number: 6984833
    Abstract: The present invention is applied to an ion implanter provided with a vacuum pressure compensation mechanism. The pressure compensation mechanism samples measured beam currents and vacuum pressures in the vicinity of wafers in preliminary implantation and stores function parameters in a memory unit which are obtained by calculating parameters of a predetermined function by fitting the relationship between the measured beam currents and the vacuum pressures. In actual implantation, the pressure compensation mechanism corrects the measured beam current using the function parameters stored as a function of the vacuum pressure, and based on the corrected beam current, the dosage control is performed. In the present invention, an actual beam loss is compensated for based on the estimation from a pressure in the vicinity of the wafers in a region downstream of a mass analysis slit.
