Abstract:
An apparatus for performing a thin film deposition on a substrate comprising:a vacuum chamber containing a thin-film particle source for generating thin-film particles to deposit a thin-film on said substrate; a substrate holder disposed in said vacuum chamber for holding said substrate having a thin-film deposition surface facing a beam of said thin-film particles projected from said thin-film particle source; a rotational means for rotating said substrate holder holding said substrate to rotate along an axis at an angle about ninety degrees relative to said thin-film deposition; and a laterally reciprocal moving means for reciprocally moving said substrate holder for holding said substrate along a direction with said beam traversing on said substrate from a first edge of said substrate to a second edge opposite said first edge of said substrate with a lateral motion traversing said beam of said thin film particles with a non-constant speed.
