    摘要: A microwave plasma ion source according to this invention is characterized by the construction of the extracting electrode in contact with the discharge chamber. The electrode is divided into a part substantially exposed to a plasma and a remaining part which is not exposed to the plasma. Moreover, both these parts are held in a state in which they are electrically connected with each other.As a result, very little P or As deposits on the surface of the electrode, and a stable high-current ion beam can be supplied over a long period of time.

    摘要: An ion source for emitting an efficient radiation of ion beam having a rectangular cross section includes a set of parallel electrodes to which a microwave power is supplied to generate a microwave electric field in an electrode gap. A DC magnetic field is applied in a direction along the opposing surfaces of the electrodes to provide a microwave discharge in the electrode gap in cooperation with the microwave electric field crossing therewith. The electrode gap or discharge space has a rectangular cross section perpendicular to a direction along which ions produced by the microwave discharge are extracted as an ion beam with a side of the cross section corresponding to the distance between the electrodes being shorter than its side crossing therewith. This allows the efficient generation of the ion beam having the rectangular cross section through one or more extraction electrodes which include rectangular slits corresponding in pattern to the above-mentioned cross section.

    摘要: An ion source equipped with an ion beam exit slit for extracting ions from plasma generated in feed gas introduced into a discharge chamber, and with gas inlet or inlets for introducing the feed gas into the discharge chamber in close proximity of the ion beam exit slit. Ion extraction can be made stably without any deposit on the ion beam exit slit even when a boron halide is used as the feed gas. The effect of the ion source can be further enhanced by adding oxygen, hydrogen or gas of an oxygen-containing compound to the feed gas, and by using a microwave.

    摘要: A microwave ion source suitable for an apparatus which requires ions of an element of high reactivity such as oxygen, fluorine, etc., the microwave ion source being arranged to transmit microwaves between outer and inner conductors of a coaxial line. An ion extraction electrode is formed at least partly of a low magnetic permeability material while an acceleration electrode is formed of a high magnetic permeability material. The acceleration electrode is formed so as to have a structure in which a low magnetic permeability material of a certain thickness is stacked on the high magnetic permeability material at a plasma chamber side and openings of ion exit holes are formed in the portion of the low magnetic permeability material. A permanent magnet constituting a magnetic field generating means is provided to surround the microwave lead-in coaxial line. The direction of magnetization of the permanent magnet is made to coincide with the axial direction of the coaxial line. The end surface of the permanent magnet at the microwave lead-in side is coupled with the periphery of the high magnetic permeability material of the acceleration electrode through another high magnetic permeability material to form a magnetic path. The plasma chamber is formed of a dielectric insulator which transmits microwaves well. It is possible to realize an ion source in which ions can be extracted with a high electric field, and in which a high current ion beam can be extracted for a long time.

    摘要: A charged particle accelerator is provided with quadrupole electrodes with surfaces that are opposed to each other and are undulated, and with an external resonance circuit. The external resonance circuit consists of a capacitor formed by the opposing electrodes, a variable capacitor provided in parallel with said capacitor, and a coil. The resonance frequency is variable. A direct current and an alternating current may be applied in a superposed manner to the quadrupole electrodes. The thus constructed accelerator can be employed for an ion implanter to implant a heavy-current ion beam of several hundred KeV to several MeV.

    摘要: In order to implant ions uniformly in a plurality of wafers, carriers, on which a plurality of wafers are mounted, are moved along a straight line one after another. An ion implanter comprises a beam sweep width controller for controlling the beam sweep width in such a manner that the area scanned with the ion beam by sweeping it coincides approximately with the shape of the wafers in which ions are to be implanted and a carrier speed controller for controlling the carrier speed, depending on the beam sweep width so that the dose of ions implanted in the wafers is uniform. The beam sweep width controller includes a detector for detecting the width of a wafer in which ions are being implanted in the one direction and a controller for varying the beam sweep width, depending on the width of the wafer thus detected. The carrier speed controller varies the carrier speed inversely proportionally to the width of the wafer thus detected.
