Abstract(in English) Many studies have concentrated on the decrease in a-Si defect density. However, several a-Si image sensor, such as the 2M-pixel charge coupled device (CCD) image sensor, suffer from the following problem: (1) a decrease in defect density causes an increase in reverse biased current. Therefore, we conducted a trial to calculate the electric field around the edge of the electric field concentration at the edge of the electrode, and (2) the electric field concentration was improved by optimizing shape of the electrode edge. In addition, we confirmed that relaxation of the electric field concentration was observed in the prepared sample.
