Title: Surface inspection apparatus
Inventor: FUKAZAWA KAZUHIKO
IPC: G01N21/956
Filed: 2001-09-13
Granted: 2003-10-01
Abstract: The invented surface inspection apparatus obtains images of a tested piece by capturing images of the tested piece with an image-capturing device while varying at least one apparatus condition (e.g., the wafer tilt angle) through apparatus condition adjustment, and determines an optimal setting condition that a surface inspection is to be conducted onto the test piece based upon the images thus obtained. As a result, the optimal setting condition for the inspection can be accurately ascertained with ease even when the pitch of a pattern formed on the surface of the tested piece is unknown. Thus, through the use of the optimal condition obtained by the way described above and the surface inspection apparatus to perform the surface inspection onto the tested piece, it is possible to perform a surface inspection while sustaining high levels of accuracy and efficiency at all times without generating judgment difference of the inspector.
