Abstract:
1. A method for heating a part within a processing chamber of a semiconductor manufacturing apparatus having a substrate in the processing chamber and performing a process on the substrate, the method comprising: generating first heating lights having a first wavelength band capable of being absorbed into a first part in the processing chamber, the first heating lights being generated by a first heating light source provided outside the processing chamber, generating second heating lights having a second wavelength band capable of passing through the first part in the processing chamber and being absorbed into a second part in the processing chamber made of a material different from that of the first part, the second heating lights being generated by a second heating light source provided outside the processing chamber, and heating the first part in the processing chamber by irradiating the first heating lights to the first part in the processing chamber, and heating the second part in the processing chamber by passing the second heating lights through the first part in the processing chamber and irradiating the second heating lights to the second part in the processing chamber.
