Patent number: 7268048Abstract: Methods of preparing conductive regions such as source/drain regions for silicidation procedures, has been developed. The methods feature removal of native oxide as well as removal of deposited arsenic based defects from conductive surfaces prior to deposition of a metal component of subsequently formed metal silicide regions. Arsenic ions implanted for N type source/drain regions are also implanted into insulator regions such as insulator filled shallow trench isolation regions. A hydrofluoric acid cycle used as a component of the pre-silicidation preparation procedure can release arsenic from the shallow trench isolation regions in the form of arsenic based defects, which in turn can re-deposit on the surface of source/drain region. Therefore pre-silicidation preparation treatments described in this invention feature removal of both native oxide and arsenic based defects from conductive surfaces prior to metal silicide formation.Type: GrantFiled: August 6, 2004Date of Patent: September 11, 2007Assignee: Chartered Semiconductor Manufacturing Ltd.Inventors: Yin-Min Felicia Goh, Simon Chooi, Teck Wee Lim, Vincent Sih, Chian Yuh Sin, Ping Yu Ee, Zainab Ismail, Cher Sian Chua

Publication number: 20050206613Abstract: A system and method for power management of an optical mouse. A mechanical displacement sensor associated with the optical mouse is used to detect movement of the optical mouse. When the optical mouse is motionless, a switch within the mechanical displacement sensor sets the optical mouse to a standby state. The standby state conserves power. When motion is detected by the mechanical displacement sensor, the switch powers up the optical mouse into its normal mode of operation.Type: ApplicationFiled: March 17, 2004Publication date: September 22, 2005Inventors: Wai Chan, Wee Lim, Chun Wong
