The Sharon is a cryo-pumped thin film evaporator with a Temescal four hearth 270° bent beam evaporation source. The system incorporates a Commonwealth Scientific Corp. ion source for in-situ sample cleaning. Fixturing in the Sharon will accept any size sample up to 3.5-inch diameter. In addition, a rotation fixture is easily installed which permits adjustable angle, 360° variable speed rotation of any size sample, up to 1.5-inch diameter. This feature is particularly useful for promoting step coverage of irregular surfaces.
The Sharon is used for the evaporation of high purity metals, e.a. Al, Au, Ni, Ge, AuGe, Ti, Pt etc., for interconnect and ohmic contact metalization for fabrication of III-V compound semiconductor and silicon device fabrication.
