Abstract: An annealing apparatus includes: a main body configured to receive a substrate; a microwave generating unit configured to generate microwaves to be transmitted to the main body; an incidence unit configured to transmit the microwaves from the microwave generating unit to the main body; and a diffraction unit disposed between the incident unit and the main body. The diffraction unit is configured to pass the microwaves therethrough before they are transmitted to the main body.
