Title: End-point detecting method in dry etching
Inventor: HASEGAWA YASUO
IPC: H01L21/302
Filed: 1986-01-29
Abstract: PURPOSE:To perform accurate detection, by detecting the end point of etching based on the results of detecting light emitting states at two or more different positions in an ion beam, thereby enhancing the contrast in detections at the end point of the etching. CONSTITUTION:Two light receiving parts 18 and 20 are provided at positions at different heights on the side wall of an etching chamber. Light emitted from a part (part A) corresponding to the path of an ion beam in the etching chamber 2 is received by the light receiving part 18. Thus the intensity of the spectrum of a material (e.g., N and N2), which is not related with etching reaction, is detected. Meanwhile, the light receiving part 20 receives light, which is emitted from the surface part (part B) of a material to be treated 6 wherein the etching is in progress. Thus the intensity of the spectrum of the material, which is yielded by the etching reaction (e.g., Si and SiF), is detected. The ratio or the difference between the light intensities, which are obtained by the two detectors is computed. By investigating the change in said values, the effects of the change in the part B due to the change in background such as a gas flow rate, pressure and gas state are removed. Thus the accurate detection of the end point can be performed.
