Tender For Mocvd Epitaxy Structure Gan Ld, bombay-Maharashtra

Tender For Mocvd Epitaxy Structure Gan Ld; 10 MOCVD epitaxy structure: GaN LD MOCVD epitaxy structure: GaN LD on free-standing GaN substrate – standard 405nm; Product Specification: MOCVD epitaxy structure: 450nm Laser Diode epi on 2” freestanding GaN Epi structure specification: 1. The epi structure will be grown on the n-type bulk GaN provided by Seen Semiconductors; 2. The final EPD level of the epi-structure will be the same as of the substrate; 3. The epi laser structure will allow for emission of laser light in the 450nm +/-10nm range with the std deviation of +/-5nm for each laser; 4. Epi specification provided by Seen Semiconductors Ltd. Seen Semiconductor will remain owner of the specification. Thickness and doping of layers will be provided in the after production report with the exception of some details which will remain confidential due to the fact that Seen is not the full owner of the specification; 5. Doping level uniformity <(>&<)> tolerance: 20%; 6. Mole fraction uniformity: 2% (in QW: 4%); 7. Mole fraction tolerance: 0.4% (in QW: 2%); 8.
