Title: Method for detecting surface flatness of semiconductor wafer
Inventor: MORITA ETSURO
IPC: G01B11/02
Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To accurately detect the presence/absence of steps on the entire polished surface of a wafer, polished by CMP(chemical-mechanical polishing) and the positions of the steps and, at the same time, to facilitate discrimination of a pattern from recessing and projecting sections. SOLUTION: The polished surface of a semiconductor wafer polished by CMP is put on the mirror surface of a semiconductor wafer to be stuck. While the polished surface of the sticking wafer is irradiated with infrared rays, the presence/absence of steps is confirmed in situ. When steps exist on the polished surface of the wafer, the progress of sticking becomes discontinuous or discontinuous sections are, left as voids, and when a large step exists, a void is left. Therefore, the positions of the steps can be confirmed from the positions of the voids. After the wafers are stuck to each other, in addition, the positions of the steps can be confirmed easily by radiating ultrasonic waves.  This method is suitable for the precise measurement of the CMP polished surface of a wafer formed with, for example, a wiring pattern, and the pattern can be discriminated from other recessing and projecting sections.
