The quantum efficiency of the photodiode is optimized by: determining, for the infrared wavelength, first thicknesses of the second layer corresponding to maximum absorptions of the photodiode, and selecting, from among the first thicknesses, a desired thickness, eoxD, so that a maximum manufacturing dispersion is smaller than a half of a pseudo-period separating two successive maximum absorption values."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of optimizing the quantum efficiency of a photodiode","description":"A photodiode has an active portion formed in a silicon substrate and covered with a stack of insulating layers successively including at least one first silicon oxide layer, an antireflection layer, a","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9812615","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
