Title: Method for detecting end point
Inventor: YAMAZAWA YOHEI
IPC: H01L21/302
Filed: 2000-02-07
Abstract: PROBLEM TO BE SOLVED: To solve the problem that in a conventional method for detecting the end point of etching of a layer to be treated is detected by utilizing emission spectroscopy, the end point of etching is detected as the point, where the etching for a layer to be treated is finished so that a base material layer is exposed and intensity of light emission of a specified wavelength varies and the base material layer is shaved and damaged by over etching at that time. SOLUTION: In a method for detecting end point, when a polysilicon layer P on a gate oxide film G is etched using a plasma, the polysilicon layer P is irradiated with light, and an end point of etching is detected by using a reflected light thereof. In this method, the polysilicon layer P is irradiated with the light, and a spectrum of interfering light made by reflection from an interface between the surface of the polysilicon layer P and the gate oxide film G is detected, and then the statistic of interference intensity of the spectrum is found, and a pseudo end point is detected based on variability with time of the statistic.
