Title: Film thickness measuring device for photoresist
Inventor: TAKAMI KATSUMI
IPC: H01L21/027
Filed: 1984-06-01
Abstract: PURPOSE:To measure the thickness of a film accurately by a method wherein the fluorescence emitted from a resist is measured and, at the same time, the reflected light corresponding to the lower surface reflection factor, and an output signal is obtained by having the ratio of the above-mentioned two measurements. CONSTITUTION:The fluorescence emitted from a resist is measured by a photoelectron tube 14 to be used for the detection of fluorescence, and the result is transferred to a signal processing circuit. At that time, the reflection factor of the lower surface of photoresist is intensely reflected to the measured value. On the other hand, the excited light reflected corresponding to the reflection coefficient of the lower surface is measured by a photomultiplier 18 to be used for detection of reflected light, and it is transmitted to a signal processing circuit 20. At this point, the signal Vf obtained by fluorescence is divided by the signal Vr obtained by reflected light, and the reflection coefficient of the lower surface is corrected. Accordingly, when the Si wafer 1 wherein a pattern is formed is two- dimensionally and mechanically scanned, signals Vf and Vr corresponding to the scanned place are obtained, and the film thickness V0 indicated by V0=Vf/kVr (k indicates constant) as their ratio can be obtained.
