Surface Analyzer

A surface analyzer for collecting two-dimensional distribution data of a plurality of different kinds of physical quantities on a same target area of a sample, for creating a display image based on the collected data, and for showing the display image on a display device, comprising:

• a) a first display processor for creating a three-dimensional image on the target area based on two-dimensional distribution data of a first physical quantity among the plurality of different kinds of physical quantities, for creating a three-dimensional color image by superposing, on the aforementioned three-dimensional image, a color distribution created on a basis of two-dimensional distribution data of a second physical quantity, and for displaying the three-dimensional color image in a first display area of the display device;
• b) a section image creator for creating, in response to an operation of a user on an operation unit, a section image intersecting a surface of the sample, at a position on the three-dimensional color image, and for superposing the section image on the three-dimensional color image;
• and
• c) a second display processor for defining, as a region of interest, a one-dimensional area at which the section image intersects the surface of the sample, for creating a graph showing distributions of or changes in values of the first and second physical quantities along the region of interest using the two-dimensional data of the first and second physical quantities, and for displaying the graph in a second display area separated from the first display area of the display device.
