Abstract :
Hybrid voltage-variable capacitors were fabricated with hyperabrupt ion-implanted doping profiles. The capacitance uniformity was within 2% over the operating voltage range. Losses in the low-bias-voltage range were reduced by a factor of 3 by a 475°C anneal in N2¿H2. A small bias-temperature instability was observed.
