HILR is provided by ELS modules for stand-alone bulk/continuous processing, or integrated in wafer processing lines in a High-Intensity Light Zone, HILZ, downstream of a wafer firing furnace. A finger drive wafer transport provides continuous shadowless processing speeds of 200-400 inches/minute in the integrated furnace/HILZ. Wafer dwell time in the peak-firing zone is 1-2 seconds. Wafers are immediately cooled from peak firing temperature of 850° C.-1050° C. in a quench zone ahead of the HILZ-ELS modules. Dwell in the HILZ is from about 10 sec to 5 minutes, preferably 10-180 seconds. Intermittent HILR exposure is produced by electronic control, a mask, rotating slotted plate or moving belt."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for reduction of solar cell LID","description":"Reduction of solar wafer LID by exposure to continuous or intermittent High-Intensity full-spectrum Light Radiation, HILR, by an Enhanced Light Source, ELS, producing 3-10 Sols, optionally in the pres","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9780252","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.
