Bipolar components that consist of p(+)n junctions have been irradiate
d by MeV protons at fluences ranging from 10(11) to 10(13) particles c
m(-2). Capacitance-voltage measurements have been used to investigate
changes in the carrier concentration profiles. Shallow donors that can
induce harmful effects in electronic devices have been studied as a f
unction of fluence, flux, and annealing parameters. (C) 1996 American
