A method and apparatus for inspecting the surface of articles, such as chips and wafers, for defects, includes a first phase of optically examining the complete surface of the article inspected at a relatively high speed and with a relatively low spatial resolution, and a second phase of optically examining with a relatively high spatial resolution only the suspected locations for the presence or absence of a defect therein.

A method and apparatus for inspecting the surface of articles, such as chips and wafers, for defects, includes a first phase of optically examining the complete surface of the article inspected by scanning its complete surface at a relatively high speed and with an optical beam of relatively small diameter, particularly a laser beam, and a second phase of optically examining with a relatively high spatial resolution only the suspected locations for the presence or absence of a defect therein.
