Abstract
A single-substrate-heat-treatment apparatus heats a semiconductor wafer by scanning the wafer with light having high energy density. Light emitted by a light source is reflected by a reflection mirror mechanism, and is then focused on the surface of the wafer on a work table via a transparent window of a process chamber. During heat treatment, the work table or reflection mirror mechanism is moved to scan the wafer surface with the light coming from the light source.
