THE METHOD OF TRANSFORMING N-CONDUCTIVE SEMI-CONDUCTOR MATERIAL INTO P-CONDUCTIVE SEMICONDUCTIVE MATERIAL WHICH CONSISTS OF THE STEPS OF GENERATING A BEAM OF ELECTRONS HAVING AN ENERGY RANGE OF BETWEEN 30 AND 200 KEY, FOCUSSING SAID BEAM AT A FIRST LOCATION ON A BODY OF SEMICONDUCTOR MATERIAL WHERE A TRANSFORMATION IS TO BE ACCOMPLISHED, LIMITING THE TIME OF IMPINGEMENT OF THE BEAM ON SAID FIRST LOCATION SUCH THAT A DOSE OF 10**16 TO 10**22 ELECTRONS PER CENTIMETER SQUARED IS IMPARTED THERETO AND PRODUCING RELATIVE MOVEMENT BETWEEN THE NORMAL AXIS OF THE ELECTRON BEAM AND THE BODY OF SEMICONDUCTOR MATERIAL SUCH THAT TRANSFORMATIONS MAY BE EFFECTED SERIALLY AT A PLURALITY OF POINTS.
