Nanoelectromechanical Logical Gates Utilising Selective Tungsten Chemical Vapor Deposition
NAND and NOR logical gates based on the electrostatically driven silicon nanoelectromechanical (NEM) switches coated tungsten (W) are designed, fabricated and evaluated. A selectively conformal W deposition on high aspect ratio silicon structures is investigated. Logical gates are successfully fabricated and all their functions have been proved. This work opens the possibility not only for producing the complex mechanical logic systems but also for a way to reducing capacitive gap width.
