Abstract
PURPOSE: To achieve a highly accurate measurement of the temperature of a sample, by checking distance between marks arranged on a sample cassette at fixed intervals using a laser interference system to detect the temperature of the sample based on difference between the detection distance and a distance at a reference temperature.
CONSTITUTION: A wafer sample 4 is inserted into a cassette 1 to be fixed on a main stage 2 and two marks A and B are arranged on the cassette 1 at a fixed interval. To measure a distance XAT-XBT between the marks A and B at a temperature T°C, the mark B is irradiated with an electron ray of an electron ray source 7 and an X motor 10 is driven from the state at which a reflection electron signal 8 is generated to keep the stage 2 moving until the reflection electron signal of the mark A is detected in the direction X. Here, XAT-XBT is obtained from the frequency of changes in the intensity due to interference detected with a laser detector 16. Temperature of a cassette, namely, a sample temperature is determined from a difference between the distance between the marks thus obtained and a distance between the marks at a reference temperature T0 and a coefficient of thermal expansion of the cassette 1.
