Abstract:
1. A holder for holding test samples used in measuring linearity of an atomic force microscope, comprising: a body having a top surface; and a plurality of inclined regions formed in the body and spaced apart along the top surface; wherein each of the inclined regions is structured and arranged to hold a test sample used to measure linearity of the atomic force microscope at one of a plurality of predefined angles, wherein the test sample comprises a patterned silicon integrated circuit chip that is used for detecting non-linearity of the atomic force microscope, each of the plurality of inclined regions comprises: a first surface that intersects the top surface at a respective one of the plurality of predefined angles; and a second surface that intersects the top surface, and the second surface intersects the first surface at an angle of approximately 90°, the top surface defines a substantially horizontal plane and the plurality of inclined regions comprises: the top surface comprises:
