Abstract
This paper discusses the numerical calculation of log nSF (surface electron density) - VG(gate voltage) curves and experiments. By compensating for the distribution tail of the main impurity by the opposite type impurity, the log nSF - VG curves can be shifted in an almost parallel manner. Fabrication of MOSFET with a desired value of residual current is possible by implanting a sufficient amount of phosphorus first, then a second boron layer near the surface.
