Patent number: 5189303Abstract: An ion source for producing wide, large area type ion beams with a mass-separation device. Four, five six or so electrode plates with ion holes at the same positions are installed at the outlet of the ion source. Second or third one of the electrodes has Wien filters at the ion holes. The Wien filter has permanent magnets and electrodes for producing a magnetic field and an electric field perpendicular to the axial direction of the ion holes.

Patent number: 4830182Abstract: A dust-tight container suitably usable in the manufacture of semiconductor microcircuits, for keeping therein a plate-like member such as a reticle, a photomask or a wafer is disclosed. The container has an elastomeric sealing member which is provided along an engaging portion between a container casing and a cover or door of the container, to achieve sufficiently complete dust-tight property of the container to thereby effectively prevent dust or foreign particles from entering into the container. At an engaging portion between the door and the container casing, a protrusion and a recess which mate at the time of closing of the door are provided. These mating protrusion and recess are formed at positions which are on the inner side of the elastomeric sealing member. This effectively prevents particles, adhered to the sealing member and scattering at the time of opening/closing of the door, from entering into the container.Type: GrantFiled: December 24, 1987Date of Patent: May 16, 1989Assignee: Canon Kabushiki KaishaInventors: Hiroshi Nakazato, Mamoru Iijima
