Patent ID: 7226849

Claim:
A method of producing multiple semiconductor components on a substrate, said method comprising the steps of: forming a predetermined relief pattern on a surface of said substrate; and epitaxially depositing a layer formed of a mixture of two or more Group III elements and two or more Group V elements on said surface wherein two of said Group III elements are Gallium (Ga) and Indium (In), and one of said Group V elements is Nitrogen (N); and wherein said relief pattern results in said layer deposited in a single step forming with a different ratio between said Gallium (Ga) and Indium (In) within areas on said surface having different relief pattern characteristics, said difference in the ratio between the Gallium (Ga) and the Indium (In) altering the amount of Nitrogen (N) which is incorporated into said layer, the different Nitrogen (N) incorporation within said different areas providing different band gaps within said different areas.
