  "abstract": "A substrate processing apparatus includes a reactor having a processing space formed therein, a fluid supply unit supplying a supercritical fluid into the processing space of the reactor, and a controller controlling the reactor and the fluid supply unit. The controller controls, in response to whether a state of the supercritical fluid supplied to the reactor satisfies a set condition, the reactor and the fluid supply unit to perform one of cleaning of the processing space by using the supercritical fluid and drying of a substrate seated in the processing space by using the supercritical fluid.",
