Abstract: |
The invention belongs to the technique area of the semiconductor elements and devices. Three layers of the isolation pole are prepared on the graphics of the first electrode. The graphics of the first layer of the isolation pole is the mesh texture with the cross section being as trapezoid shape. The cross section of the lines on the second layer and the third layer of the isolation pole possess the shape with big at the upper and small at the lower. Then, the organic function layer and the second electrode are deposited in sequence. The shadow effect caused by the shape with big at the upper of the second layer and the third layer makes the second electrode possible to be partitioned. The first layer of the isolation pole being equivalent to 'insulating base' prevents the short circuit between the electrodes. |
