Abstract
PURPOSE: To reduce the increase in the dark current produced to the pick up unit, by increasing the spectral sensitivity for short wave length region for ineident light without lowering the amount of charge dealed for the photo gate electrode.
CONSTITUTION: The photo gate electrode layer 1 of the solidstate pick up unit is formed in the silicon substrate, forming the region in high concentration diffusion of the same conduction type. further, the channel stopper region 2 fixing the photo gate electrodes 3n, 3n+1 is formed, the channel stopper regions 13 to 15 for the part present in the photo detection window not covered with the photo shield films 4,5 of the region 2 are removed, and the windows 16 to 18 made on the electrode layer 1 in which all incident lights reach the substrate are formed. Then, the gate oxide films 11, 12 are formed on the upper part of the regions 13 to 15 of the windows 16 to 18, taking the constitution not present for the electrode layer 1, The constitution is made that the high concentration diffusion region passes through the center of the windows 16 to 18 made on the electrode layer 1 of the gate electrodes 3n and 3n+1.
