Publication number: 20240120363Abstract: A self-aligned plug may be formed between deep trench isolation (DTI) etching cycles. Accordingly, etch depth in areas of a pixel sensor with large CDs (e.g., at an X-road) is reduced, which prevents trench loading. As a result, a floating diffusion (FD) region, associated with photodiodes of the pixel sensor, is not damaged during the DTI etching cycles. Reduced chances of damage to the FD region improves performance of the pixel sensor and prevents electrical shorts and failures, which increases yield and conserves time and raw materials used in forming the pixel sensor.Type: ApplicationFiled: January 5, 2023Publication date: April 11, 2024Inventors: Ming-Chyi LIU, Jiech-Fun LU, Shih-Chang LIU, Ru-Liang LEE
