Abstract
Amorphous silicon (aSi) voltage-controlled, variable capacitors (varactors) are utilized as rf amplitude modulators, such as for amplitude modulating the rf applied to an acoustic ink printhead. Large area fabrication processes are employed for vertically integrating these varactors with such printheads or other devices.
