Zusammenfassung:This invention discloses one process method for automatic self-calibrating silicon block layer, which comprises the following steps: firstly growing first layer of silica dioxide by use of CVD method; then using HDP method to grow second layer of silica dioxide on the first layer of silica dioxide layer. The invention can solve the stuff ability problem between calibration block layer and multiple transistor lines to overcome the whole phenomenon to lower leakage current.
