A trench is formed in a semiconductor substrate, around and between a plurality of pixel regions of the semiconductor substrate. A cap is formed using epitaxy to seal a gap between sidewalls of the trench. Pixel sensors corresponding to the plurality of pixel regions are formed over or within the corresponding pixel regions. An image sensor resulting from the method is also provided."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for forming deep trench spacing isolation for CMOS image sensors","description":"A method for manufacturing an image sensor with deep trench spacing isolation is provided.
