摘要： An ion implantation apparatus includes a beam scanner that provides reciprocating beam scanning in a beam scanning direction, a beam measurer that measures a beam current intensity distribution in the beam scanning direction at a downstream of the beam scanner, and a controller. The controller includes a scanning waveform preparing unit that determines whether or not a measured beam current intensity distribution measured by the beam measurer with use of a given scanning waveform fits a target non-uniform dose amount distribution, and that, in a case of fitting, correlates the given scanning waveform with the target non-uniform dose amount distribution.

摘要： In an ion implantation apparatus, an interruption member interrupts an ion beam B in the middle of a beam line. A plasma shower device is provided at the downstream side of the interruption member in the beam line. A control unit causes the interruption member to interrupt the ion beam B during an ignition start period of the plasma shower device. The interruption member may be provided at the upstream side of at least one high-voltage electric field type electrode in the beam line. A gas supply unit may supply a source gas to the plasma shower device. The control unit may start the supply of the source gas from the gas supply unit after the ion beam B is interrupted by the interruption member.

摘要： A multistage quadrupole lens system in an ion implantation apparatus includes a first quadrupole lens and a third quadrupole lens. A first bore radius of the first quadrupole lens may be smaller than a third bore radius of the third quadrupole lens. The multistage quadrupole lens system may further include a second quadrupole lens placed between the first quadrupole lens and the third quadrupole lens. A second bore radius of the second quadrupole lens may take a value lying between the first bore radius of the first quadrupole lens and the third bore radius of the third quadrupole lens (i.e., an intermediate value between them).

摘要： Provided is a beam irradiation apparatus including: a beam scanner that is configured such that a charged particle beam is reciprocatively scanned in a scanning direction; a measurement device that is capable of measuring an angular component of charged particles incident into a region of a measurement target; and a data processor that calculates effective irradiation emittance of the charged particle beam using results measured by the measurement device. The measurement device measures a time dependent value for angular distribution of the charged particle beam. The data processor transforms time information included in the time dependent value for the angular distribution to position information and thus calculates the effective irradiation emittance. The effective irradiation emittance represents emittance of a virtual beam bundle, the virtual beam bundle being formed by summing portions of the charged particle beam which are incident into the region of the measurement target.

摘要： An ion implantation apparatus includes a beam scanning unit and a beam parallelizing unit arranged downstream thereof. The beam scanning unit has a scan origin in a central part of the scanning unit on a central axis of an incident ion beam. The beam parallelizing unit has a focal point of a parallelizing lens at the scan origin. The ion implantation apparatus is configured such that a focal position of the incident beam into the scanning unit is located upstream of the scan origin along the central axis of the incident beam. The focal position of the incident beam into the scanning unit is adjusted to be at a position upstream of the scan origin along the central axis of the incident beam such that a divergence phenomenon caused by the space charge effect in an exiting ion beam from the parallelizing unit is compensated.

摘要： An ion generation method uses a direct current discharge ion source provided with an arc chamber formed of a high melting point material, and includes: generating ions by causing molecules of a source gas to collide with thermoelectrons in the arc chamber and producing plasma discharge; and causing radicals generated in generating ions to react with a liner provided to cover an inner wall of the arc chamber at least partially. The liner is formed of a material more reactive to radicals generated as the source gas is dissociated than the material of the arc chamber.
