Title: Etching method for semiconductor substrate
Inventor: OKUYAMA NOBORU
IPC: H01L21/302
Filed: 1977-11-22
Abstract: PURPOSE: To perform etching correctly with high accuracy, independently of the temperature and  concnetration of etching solution, number of substrates and concentration of etching solution,  number os substrates and etching prevention pattern, by utilizing the interferrence of light.   
     CONSTITUTION: The substrate 5 having the insulation pattern of diffractive rate and film thikness  according to the amount of etching desired is set in front of the surface of the stand 2 in the transmitting vessel 1. When mono color light is projected 3 on the pattern with angle θ1 and the reflection light is detected 4, since the pattern size is sufficiently more fine than the diameter of the laser  beam of He-Ne laser to which the pattern size is projected, mutual interference is caused to the  reflection light on the pattern. The depth l is increased with the progress of etching and the  intensity of reflection light is periodically changed with the difference of optical length of the light  paths A, B and C. Accordingly, the amount of etching from the start of etching to the first maximum reflection interference strength point is dependent on the film thickness of the pattern 11,  and the amount of etching for each substrate 5 can respectively be calculate with the etching  solution, pattern film, diffractive rate of substrate, laser light wavelength, incident angle, and  num ber of times of maximum reflection strength detected, and it is very accurate.
