ROI Calculation Logic

Assuming a 10% defect rate from organic film degradation in traditional stacked image sensor manufacturing, this technology could reduce the defect rate to 2%. For an annual production of 1 million units at a manufacturing cost of $10/unit (AI est.), the direct cost benefit from defect reduction is 1,000,000 units × (10%-2%) × $10/unit = ~$800K (AI est.). Including savings from reduced rework and quality assurance, the total economic impact could exceed ~$1M annually (AI est.).
