Patent number: 7586668Abstract: A method for forming a MEMS device is disclosed, where a final release step is performed just prior to a wafer bonding step to protect the MEMS device from contamination, physical contact, or other deleterious external events. Without additional changes to the MEMS structure between release and wafer bonding and singulation, except for an optional stiction treatment, the MEMS device is best protected and overall process flow is improved. The method is applicable to the production of any MEMS device and is particularly beneficial in the making of fragile micromirrors.Type: GrantFiled: March 29, 2005Date of Patent: September 8, 2009Assignee: Texas Instruments IncorporatedInventors: Satyadev R.

Patent number: 7586669Abstract: A micro mirror device includes a hinge supported by a substrate and a mirror plate tiltable around the hinge. The hinge is configured to produce an elastic restoring force on the mirror plate when the mirror plate is tilted away from an un-tilted position. The micro mirror device also includes a controller that can produce an electrostatic force to overcome the elastic restoring force to tilt the mirror plate from the un-tilted position to an “on” position or an “off” position. The electrostatic force can counter the elastic restoring force to hold the mirror plate at the “on” position or the “off” position.Type: GrantFiled: October 27, 2006Date of Patent: September 8, 2009Assignee: Spatial Photonics, Inc.Inventor: Shaoher X.
