Abstract
PURPOSE: To form MIS . FET having good PN bonding, by growing Si3N4 film on the layer containing same by making Si base plate and N2 react by the direct heat nitrogenous reaction, diffusing therein heavy metal impurity contained in Si base plate and afterwards removing same, sticking newly SiO2 film and forming the element zone.
