Patent ID: 7579204

Claim:
A semiconductor light emission device production method in which stripes of two multilayers having different emission wavelengths for a plurality of devices are formed on a substrate, the method comprising the steps of: depositing a first multilayer structure including an active layer on said substrate, said first multilayer structure useable to form a light emitting device which emits light of a first wavelength; selectively etching said first multilayer structure to form a plurality of pairs of parallel adjoining stripes of said first multilayer structure; depositing a second multilayer structure including an active layer on said substrate, said second multilayer structure useable to form a light emitting device which emits light of a second wavelength different than that of the first multilayer and said stripes of said first multilayer structure; selectively etching said second multilayer structure to form a plurality of pairs of parallel adjoining stripes of said second multilayer structure on said substrate, a pair of stripes of said second multilayer structure being between pairs of said stripes of said first multilayer structure; and dividing said substrate between adjoining stripes of the pairs of stripes of said first multilayer structure also and between adjoining stripes of the pairs of stripes of said second multilayer structure to divide it into semiconductor light emission devices provided with a stripe of said first multilayer structure and and a stripe of said second multilayer structure.
