Claim 18:
19. An apparatus for treating a substrate, the apparatus comprising:
a process chamber having a process space in which the substrate is treated with a fluid in a supercritical state;
a support unit provided in the process space and configured to support an edge region of a bottom surface of the substrate;
a fluid supply unit configured to supply the fluid into the process space;
a filler member disposed to face the substrate placed on the support unit in the process space, the filler member being located below the support unit; and
a measurement unit provided in the filler member and configured to measure a state in the process space,
wherein the process chamber includes,
an upper body in which the support unit is installed,
a lower body in which the filler member is installed, the lower body being configured to provide the process space together with the upper body,
an actuator configured to move one of the upper body and the lower body relative to the other,
an upper supply line configured to supply the fluid into the process space and provided in the upper body, and
a lower supply line configured to supply the fluid into the process space and provided in the lower body,
wherein the filler member is located between the lower supply line and the substrate,
wherein the measurement unit includes,
a communication module, and
one or more of a temperature sensor, a pressure sensor, and a leveling sensor configured to measure posture of the apparatus,
wherein the filler member includes a housing including a first material and a transmissive window including a second material and installed in the housing, the transmissive window being capable of transfer of a wireless communication signal, and
wherein the first material has a higher heat transfer rate than the second material.
