Abstract
An optics plate for an ion implantation system, the optics plate comprising a pair of aperture assemblies. Each pair of aperture assemblies respectively comprises a first aperture member, a second aperture member; and an aperture fastener, wherein the aperture fastener fastens the first aperture member to the second aperture member. An aperture tip may be also fastened to the second aperture member. One or more of the first aperture member, second aperture member, aperture tip, and aperture fastener is made of one or more of a refractory metal, tungsten, lanthanated tungsten alloy, yttrium tungsten alloy, and/or graphite and silicon carbide. The aperture assemblies may define an extraction electrode assembly, a ground electrode assembly, or other electrode assembly in the ion implantation system. The aperture fastener may be a screw and a bevel washer. The first aperture member may be operably coupled to a base plate via an aperture assembly fastener.
