Abstract:
In one embodiment, a micro device is formed by depositing a sacrificial layer over a metallic electrode, forming a moveable structure over the sacrificial layer, and then etching the sacrificial layer with a noble gas fluoride. Because the metallic electrode is comprised of a metallic material that also serves as an etch stop in the sacrificial layer etch, charge does not appreciably build up in the metallic electrode. This helps stabilize the driving characteristic of the moveable structure. In one embodiment, the moveable structure is a ribbon in a light modulator.

Abstract:
A method for processing input/output request packets (IRPs) directed to Data Volumes having a meta-data extent and at least one data extent begins by initiating an IRP. The IRP is evaluated by a volume filter to determine a meta-data extent to handle the IRP. The IRP is directed by the volume filter to the appropriate meta-data extent. The IRP is redirected from the meta-data extent to at least one data extent associated with the meta-data extent.
