Larger size output node and bigger gate capacitor of amplifier were designed to ensure the total capacitor reach the level of 4.5×10^-13 F and the experiment process of new design configuration was carried out. It was verified that after optimization of the design， the Charge to Voltage Factor of the ultraviolet linear CCD could accurately achieve 0.352 μV/e^- based on the development of parameter calibration， structure optimization， process testing， parameter examination and certifying. The results could finally meet the special needs of the space flight system on the basis of the improved CCD’s performance parameters， such as high level full-well capacity up to 1.0×10⁷ e^-/pixel， 3.5~4 V output voltage and 0.35 μV/e^- low level Charge to Voltage Factor with one or two order of magnitude smaller than traditional CCD.
