    摘要: A method for etching semiconductor wafers in an etching apparatus including an etching bath filled with an etchant and capable of setting liquid temperature and process sequence, comprises selecting a predetermined etching program suitable for etching of the semiconductor wafer, counting the number of the semiconductor wafers to be charged in the etching bath before the etching, calculating a temperature drop of the etchant based on the counted number, setting the liquid temperature of the etchant to an initial temperature B obtained by adding the temperature drop of the etchant to a predetermined etching temperature A, charging the semiconductor wafers in the etching bath at a predetermined timing to etch the semiconductor wafers, and setting the liquid temperature at the predetermined etching temperature A, immediately before or after the liquid temperature reaches the initial temperature B.
