Patent ID: 8300221

Claim:
A minute measuring instrument for high speed and large area, comprising: a focused-beam ellipsometric part which is positioned above a specimen, includes a Z-translator and an ellipsometer, and measures optical properties of the specimen at higher speed by focusing polarized light outputted from the ellipsometer onto the specimen and detecting light reflected from the specimen, thereby detecting a singular optical point on a surface of the specimen, wherein the ellipsometer is moved upward or downward by using the Z-translator to focus the polarized light; and a minute measuring part which is positioned above the specimen, includes a Scanning Probe Microscope having a Z-scanner, a probe, an XY-scanner, and an XY-translator, and measures a position in a vicinity of the singular optical point at an atom level, wherein the probe is spaced apart from the focused-beam ellipsometric part by a predetermined distance in a horizontal direction and the specimen is moved in the horizontal direction by the XY-translator when the singular optical point is detected.
