Publication number: 20250072143Abstract: An electrode controls transmittance of a blocking layer over a photodiode of a pixel sensor (e.g., a photodiode of a small pixel detector) by changing oxidation of a metal material included in the blocking layer. By using the electrode to adjust transmittance of the blocking layer, pixel sensors for different uses and/or products may be produced using a single manufacturing process. As a result, power and processing resources are conserved that otherwise would have been expended in switching manufacturing processes. Additionally, production time is decreased (e.g., by eliminating downtime that would otherwise have been used to reconfigure fabrication machines.Type: ApplicationFiled: November 6, 2024Publication date: February 27, 2025Inventors: Li-Wen HUANG, Chung-Liang CHENG, Ping-Hao LIN, Kuo-Cheng LEE

Patent number: 12191327Abstract: The present disclosure relates to a CMOS image sensor, and an associated method of formation. In some embodiments, the CMOS image sensor comprises a substrate and a transfer gate disposed from a front-side surface of the substrate. The CMOS image sensor further comprises a photo detecting column disposed at one side of the transfer gate within the substrate. The photo detecting column comprises a doped sensing layer comprising one or more recessed portions along a circumference of the doped sensing layer in parallel to the front-side surface of the substrate. By forming the photo detecting column with recessed portions, a junction interface is enlarged compared to a previous p-n junction interface without recessed portions, and thus a full well capacity of the photodiode structure is improved.Type: GrantFiled: November 2, 2023Date of Patent: January 7, 2025Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Chia-Yu Wei, Hsin-Chi Chen, Kuo-Cheng Lee, Ping-Hao Lin, Hsun-Ying Huang, Yen-Liang Lin, Yu Ting Kao

Publication number: 20240323555Abstract: An image sensor device may include a pixel sensor array and a black level correction (BLC) region. The BLC region may include a sensing region in a substrate and a light-blocking layer above the sensing region. An anti-reflection array may be formed in the light-blocking layer. The anti-reflection array includes holes, trenches, and/or other structural features such that the light-blocking layer includes two or more areas in which the top surface of the light-blocking layer is at different heights in the image sensor device. The different heights of the top surface of the light-blocking layer reduce the likelihood of light being reflected off of the light-blocking layer and toward the pixel sensor array. The anti-reflection array may reduce the likelihood of occurrence of flares or hot spots in images generated by the image sensor device, which may increase the image quality of the images generated by the image sensor device.Type: ApplicationFiled: March 24, 2023Publication date: September 26, 2024Inventors: Kuo-Cheng LEE, Ping-Hao LIN, Yun-Wei CHENG, Bo-Ge HUANG
