    • An apparatus for forming a thin film using microwave and a method therefor are provided. The apparatus for forming a thin film on a wafer by densifying predetermined soot on a wafer, when the wafer and the soot form a sample, includes a microwave sintering furnace for sealing the sample and exposing the sample to microwave, thus sintering the sample, a sintering furnace atmosphere maker for controlling the state, being the atmosphere of air inside the microwave sintering furnace, a temperature sensor/controller for sensing a temperature inside the microwave sintering furnace, comparing the temperature with a predetermined reference temperature, and outputting an error temperature, and a microwave power source for generating microwave of a predetermined temperature with reference to the error temperature output from the temperature sensor/controller and applying the microwave to the microwave sintering furnace. It is possible to rapidly form a film of a fine and uniform structure by densification using microwave.
