Integration of nanoelectromechanical (NEM) relays with silicon CMOS with functional CMOS-NEM circuit

Abstract

This paper demonstrates electrical results of an integrated Si CMOS-electrostatically actuated nanoelectromechanical (NEM) relay circuit. This is an initial step towards realizing previously proposed NEM-CMOS hybrid circuits that predict various benefits compared to CMOS-only circuits. In this work, an e-beam patterned laterally actuated Pt NEM relay is fabricated at CMOS-compatible temperatures (≤ 400 °C) on top of CMOS and is driven by an on-chip CMOS inverter at V <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">DD</inf> = 6 V.
