February 15, 2013 -- 1. Singapore, 15 Feb 2013 - A*STAR’s Institute of Microelectronics (IME) and Stanford University will collaborate to advance innovations in nano-electromechanical systems (NEMS) switch technology for ultra low power digital systems. The use of NEMS switches in digital systems such as laptops and smart phones can extend operational time of existing batteries, thereby increasing energy efficiency of such devices.
2. The higher energy efficiency of NEMS switches stems from its ability to effectively stamp out leakage currents that occur during passive standby mode. Leakage current is one of the leading sources of power consumption in digital systems based on traditional semiconductor switches. By replacing these traditional switches with NEMS switches, the total power consumption of a digital block can be reduced by up to 10x.
3. Under the agreement, IME and Stanford University will jointly develop the NEMS fabrication process and device. The project will proceed in two phases, with the first phase focused on demonstrating the reliable operation of the NEMS switch by this year.
4. On the joint project, Dr Lee Jae Wung, the IME Scientist leading the project, said, “One of the challenges in building a reliable NEMS switch is in achieving Thin Film Encapsulation to protect the switch structure and the contact materials from degradation and oxidation by providing proper vacuum condition and/or filling inert gas inside the cavity. IME’s capabilities in back end of line compatible materials and processes are expected to contribute strongly in this area.”
5. “NEMS relay has proven to be an effective complement to conventional Si CMOS technology for reducing power consumption. The collaboration with IME will advance this device technology to a manufacturing process that is suitable for co-integration with Si CMOS in practical applications,” said Professor Philip Wong, Willard R. and Inez Kerr Professor in the School of Engineering at Stanford University.
