Patent ID: 7759259

Claim:
A method of manufacturing a semiconductor device including heating a semiconductor substrate, comprising: forming a cap film on a surface of the semiconductor substrate; selectively removing the cap film at least from an upper surface of an edge of the semiconductor substrate, a bevel surface of the edge of the semiconductor substrate and a side surface of the edge of the semiconductor substrate; selectively removing at least a device-forming film formed on the upper surface of the edge of the semiconductor substrate, the bevel surface of the edge of the semiconductor substrate and the side surface of the edge of the semiconductor substrate; and heating the semiconductor substrate by irradiating the semiconductor substrate with light having a pulse width of 0.1 milliseconds to 100 milliseconds from a light source after removing the cap film and the device-forming film, wherein the cap film has a lower reflectance at a peak wavelength of the light than the semiconductor substrate.
