            Abstract : 
A method for measuring very low leakage current is presented. The method, named the variable Vpc method, is capable of detecting leakage current lower than 10-14 A in the area of 8.7×9.4 μm2 using a dynamic RAM (DRAM) cell. This method is used to measure the leakage current caused by oxidation-induced stacking faults (OSFs) originating in a Si wafer. The leakage current of OSFs is evaluated quantitatively
