Patent number: 8089052Abstract: An ion implanter system including an ion source for use in creating a stream or beam of ions. The ion source has an ion source chamber housing that at least partially bounds an ionization region for creating a high density concentration of ions within the chamber housing. An ion extraction aperture of desired characteristics covers an ionization region of the chamber. In one embodiment, a movable ion extraction aperture plate is moved with respect to the housing for modifying an ion beam profile. One embodiment includes an aperture plate having at least elongated apertures and is moved between at least first and second positions that define different ion beam profiles. A drive or actuator coupled to the aperture plate moves the aperture plate between the first and second positions. An alternate embodiment has two moving plate portions that bound an adjustable aperture.Type: GrantFiled: April 14, 2009Date of Patent: January 3, 2012Assignee: Axcelis Technologies, Inc.Inventors: Daniel Tieger, William DiVergilio, Edward Eisner, Michael Graf
