Abstract:
A method of measuring temperature in a pattern drawing apparatus comprising:a drawing chamber for drawing a pattern on a substrate; a stage within the drawing chamber; a standby chamber connected to the drawing chamber; a thermostatic device within the standby chamber; and a connection part located at two places along a transfer route within the pattern drawing apparatus; the method comprising: transferring a dummy substrate comprising a temperature measuring device and a terminal connected to the temperature measuring device into the thermostatic device; transferring of the dummy substrate from the thermostatic device to the drawing chamber while pausing at the two places along the transfer route, the two places comprising in the thermostatic device and on the stage; measuring the temperature of the dummy substrate at the two places using the temperature measuring device; transferring the temperature measured at the two places from the dummy substrate to the connection parts via the terminal of the dummy substrate; calculating a temperature distribution of temperature measurements taken along the transfer route; and controlling temperature along the transfer route on the basis of the temperature distribution calculated.
