Patent ID: 7026179

Claim:
A method of manufacturing a semiconductor light emitting device using a nitride III-V compound semiconductor substrate in which nitride III-V compound semiconductor layers are formed on a substrate of a material different from those of said nitride III-V compound semiconductor layers, comprising: just before the start of at least one process, the relation 0< D <(2 /CZ )cos −1 (1 −HCZ ) being satisfied when the maximum dimension along the plane of said substrate of said material is D (cm), warpage of said substrate of said material is in the range of 0<H≦70×10 −4 (cm), Z=(thickness of nitride III-V compound semiconductor layers)/(thickness of the substrate of said material), and C (cm −1 ) is the proportionality constant when the radius of curvature ρ (cm) of said substrate of said material is expressed as 1/ρ=CZ.
