Abstract:
1. An atomic force microscope apparatus for performing testing comprising: a sample holder for holding a first planar thin film; an arm comprising a rounded end piece including a second rounded thin film wherein a radius of curvature of the rounded piece exists along a contact surface between the first film and the second film, and wherein the arm and the sample holder are capable of relative movement therebetween to establish a contact between the first thin film and the second thin film; and a measurement circuit electrically connected to the first in film and the second thin film, for making a measurement related to a characteristic related to the first film and the second film contacting, wherein the measurement circuit is a contact resistance measurement circuit for making a measurement of a contact resistance between the first thin film and the second thin film when the contact between the first thin film and the second thin film is established.
