MICROWAVE HEATING APPARATUS

摘要

A microwave heating apparatus includes a processing chamber configured to accommodate a substrate; a substrate holding unit configured to hold and rotate the substrate in the processing chamber; a microwave generating source configured to generate a microwave; and a plurality of microwave inlet ports formed at a surface of the processing chamber which faces the substrate in the processing chamber, each of the microwave inlet ports having an opening area that gradually becomes wider toward the substrate. The microwave generated by the microwave generating source is irradiated to the substrate in the processing chamber through the microwave inlet ports to heat the substrate.
