Nanoelectromechanical (NEM) switches are a candidate to replace solid-state transistors due to their low power consumption. However, the reliability of the contact interface limits the commercialization of NEM switches, since for practical purposes, the electrical contact should be able to physically open and close up to a quadrillion (1015) times without failing due to adhesion (by sticking shut)...
Strips of electrically conductive adhesive were printed on a test PCB. Strips were processed by a standard curing process and then aged at the temperature of 125 oC. One group of samples was aged in an oven; the second group was heated with current pulses of high intensity. Ageing was carried out 150 hours. The frequency, amplitude and pulse duty cycle were changed. The strip resistance was measured...
This article discusses anti-stiction coating with conductive self-assembled monolayer (SAM) for ohmic contact microelectromechanical system (MEMS) switches. As we reported in the previous study, capillary force is a dominant factor of stiction in the air, and a hydrophobic SAM and Au coating can reduce the capillary force by preventing the formation of the liquid meniscus. In this study, we measured...
