NT25: VLSI MEMS Switch

Qingquan Liu
2006

Two important advantages of MEMS switches are their ability to survive heat and radiation. In addition, there has been increasing demand for passing transistor replacement in specific reconfigurable computing and signal routing application; passing transistors used in VLSI exhibit on-state resistances of thousands of ohms or more, which causes signal delay and increased power consumption. In this project, the design, fabrication and characterization of MEMS contact switches customized for VLSI are presented, herein referred to as “VLSI MEMS switches”.

NT18: MEMS RF Switch with Liquid Gallium Contacts

Qingquan Liu
2006

A self-healing MEMS RF switch, which utilizes liquid gallium contacts to take the place of the traditional metal-to-metal hard contacts, is proposed in this project. Electrostatic actuation is used to drive a silicon nitride diaphragm with upper electrodes. When the diaphragm is pulled down by the electrostatic force, small droplets of liquid gallium work as an interface between the upper and lower electrodes. The loss of the gallium droplets can be avoided due to the unwettability of the material surrounding the contact areas. In this project, hermit package and 1A DC current...
