Term (Index) Definition
base width  distance between metallurgical emitter and collector junctions in bipolar transistor; key geometrical feature of the bipolar transistor defining its peformance; narrower the base more efficient transfer of minority carriers from the emitter to collector across the base, and hence, better performing transistor.
base  region in bipolar transistor sandwiched between emitter and collector; typically n-type so that highly mobile electrons act as minority carriers in the base; should be very thin to allow rapid transfer of minority carriers from emitter to collector; electric field is created in the base by nonuniform doping to accelerate minority carriers moving from emitter to collector.
metallurgical junction  plane in the p-n junction at which concentration of acceptors is the same as concentration of donors.
metallurgical junction  term refers to p-n junction; interface between the n-doped and p-doped regions in the junction, or the plane in which ND = NA.
