Abstract
p+-n diodes were fabricated on n-type, <111>, bulk silicon wafers using a standard bipolar process. Reactive ion etching, of silicon dioxide was performed over the diode junction. The forward current-voltage characteristics of the reactive ion-etched samples show an increase in recombination current and deterioration of the diode ideality factor, compared to the control unetched samples and samples prepared by normal wet etch process. The reverse I-V characteristics show a high leakage current and a lowered breakdown voltage. Annealing of these diodes at different temperatures shows a recovery in the I-V characteristics and an increase in breakdown voltage.
