HIGH-FREQUENCY HEATING DEVICE, SEMICONDUCTOR MANUFACTURING DEVICE, AND LIGHT SOURCE DEVICE

摘要

A high-frequency heating device including: a solid-state oscillator that generates a microwave; an amplifier that amplifies the microwave generated by the solid-state oscillator; an isolator that is connected to a stage subsequent to the amplifier, and blocks a reflected wave directed from an object exposed with the microwave; an antenna that irradiates the microwave toward the object; and a metal cavity that traps therein the microwave irradiated to the object.
