A METHOD OF CONTROLLING THE RATE OF ACTIVATION OF A SEMICONDUCTOR COMPRISING THE STEPS, PASSING HYDROGEN INTO AN ACTIVATION ZONE WHEREIN THE HYDROGEN IS PREACTIVATED, CUASING SAID PREACTIVATED HYDROGEN TO LEAVE AND MOVE AWAY FROM SAID ACTIVATION ZONE THEREBY ALLOWING A PORTION OF SAID PREACTIVATED HYDROGEN TO BECOME UNACTIVATED, THE PROPORTION OF UNACTIVATED HYDROGEN TO PREACTIVATED HYDROGEN BEING PROPORTIONAL TO THE DISTANCE FROM SAID ACTIVATION ZONE, AT A DISTANCE WHEREIN A DESIRED RATIO OF PREACTIVED TO UNACTIVATED HYDROGEN OCCURS BRINGING SAID MIXTURE OF PREACTIVATED AND UNACTIVATED HYDROGEN INTO CONTACT WITH AN ELEMENT REACTIVE WITH PREACTIVATED HYDROGEN TO FROM A GASEOUS HYDRIDE TO THEREBY FORM A MIXTURE OF A GASEOUS HYDRIDE AND UNACTIVATED HYDROGEN IN A DESIREB RATIO, BRINGING SAID MIXTURE OF GASEOUS HYDRIDE AND UNACTIVATED HYDROGEN INTO CONTACT WITH A SEMICONDUCTOR, THE SURFACES OF SAID SEMICONDUCTOR BEING AT A TEMPERATURE SUFFICIENTLY HIGH TO CAUSE SAID GASEOUS HYDRIDE TO DIASSOCIATE INTO SAID ELEMENT AND HYDROGEN WHILE IN CONTACT WITH THE SEMICONDUCTOR AND THEREBY ACTIVATE SAID SEMICONDUCTOR WITH A CONTROLLED AMOUNT OF SAID ELEMENT.
