Long-range proton implantation has been carried out through double-barrier diodes, as may be required during vertical monolithic-integration. The anneal-induced recovery of the I-V characteristics is shown to improve if the implantation is carried out above room-temperature. After annealing, the peak current through one proton-implanted sample was higher than that before implantation.
