Abstract

Variations in topography and material properties of the surface layer of a body are observed in microscopic imaging using a scanning capacitance probe. The acronym SCaM identifying the process and apparatus is derived from the phrase scanning capacitance microscope. The material properties observable by SCaM are the surface-electric property representative of the complex dielectric constant of the surface material and the surface-mechanical property representative of the elastic constant of the surface material.
