  • Abstract
    Planar, MMIC compatible, multi-junction varactors have been fabricated using a single n-type epitaxial layer followed by multiple energy Mg+ ion implantation. The junctions, numbering between 1 and 4 (=N), were formed laterally by selective implantation masking. Current-voltage measurements of the devices show the benefits of the stacking with breakdown voltage almost proportional to N
