  • Patent number: 9204500
    Abstract: In the microwave heating apparatus, four microwave introduction ports are arranged at positions spaced apart from each other at an angle of about 90° in a ceiling portion of a processing chamber in such a way that the long sides and the short sides thereof are in parallel to inner surfaces of four sidewalls. The microwave introduction port are disposed in such a way that each of the microwave introduction ports are not overlapped with another microwave introduction port whose long sides are in parallel to the long sides of the corresponding microwave introduction port when the corresponding microwave introduction port is moved in translation in a direction perpendicular to the long sides thereof.
