摘要： At each measurement time, reflected light from a semiconductor wafer W or the like by measurement light from a measurement light source 11 is coupled to reference light from a reference light generating section 14, and interference light is detected by a photodetector 15. A raw thickness value calculating section 16b selects two light intensity peaks corresponding to the upper and lower surfaces of the wafer W from a light intensity distribution between an interference light intensity and a reference optical path length and calculates a raw thickness value. A statistical thickness value calculating section 16c executes statistical processing including data sorting, determination whether the raw thickness value falls within an allowable numerical value range, and determination of a thickness change line, thereby obtaining a statistical thickness value. With this arrangement, a thickness measuring apparatus and thickness measuring method capable of measuring the thickness of a semiconductor wafer during execution of wet etching independently of the presence of an etchant, and a wet etching apparatus and wet etching method using the thickness measuring apparatus and method are implemented.
