Filed:

Feb 22, 2006

Appl. No.:

11/360131

Inventors:

Chun-chen Wu - Hsinfeng, CN
Patrick F. Brinkley - San Mateo CA, US

Assignee:

QUALCOMM MEMS Technologies, Inc. - San Diego CA

International Classification:

H01L 21/00

US Classification:

438 48, 438 50, 438 51, 438 53, 257E21001

Abstract:

A method of fabricating a MEMS device includes conditioning of an insulating layer by applying a voltage across the insulating layer via a conductive sacrificial layer for a period of time, prior to removal of the conductive sacrificial layer. This conditioning process may be used to saturate or stabilize charge accumulated within the insulating layer. The resistance across the insulating layer may also be measured to detect possible defects in the insulating layer.

Abstract:

Methods of fabricating a static interferometric image device and static interferometric image device formed by the same are disclosed. In one embodiment, a method includes providing a substrate. A plurality of liquid layers are formed over the substrate by an inkjet process such that the layers are lateral to one another. The liquid layers contain a solidifiable material or particles. Then, the plurality of liquid layers are solidified to form a plurality of solid layers. In some embodiments, the substrate includes pre-defined cavities, and the liquid layers are formed in the cavities. In other embodiments, the substrate includes a substantially planar, stepped, or continuously transitioning surface, and the liquid layers are formed on the surface. The inkjet process provides optical fillers or spacers for defining interferometric gaps between absorbers and reflectors in the display device, based at least partially on an image that the display device is designed to display.

US Classification:

307 43, 363132, 438 64, 257E31117

Abstract:

A photovoltaic solar panel includes a front glass, a back glass, and a photovoltaic (PV) power generating layer encapsulated between the front glass and the back glass. The PV power generating layer is configured to convert ambient electromagnetic energy, received through the front glass, to a direct current (DC) power output. The PV solar panel also includes at least one component, disposed behind the PV power generating layer, selected from the group consisting of: a direct current to alternating current (DC-AC) inverter configured to convert the DC power output from the PV power generator to an alternating current (AC) power output, a battery, and an antenna.

US Classification:

349117

Abstract:

A liquid crystal display and corresponding method are provided for reducing display image reflections off of a reflection point on an external medium (e. g. cockpit canopy or automotive windshield). A retarder is provided on the front side of the display so that the polarization direction of the display image is substantially parallel to the plane of incidence when the image reaches the reflection point. Additionally, the angle of incidence. THETA. sub. i is substantially matched to the Brewster angle. THETA. sub. p in order to maximize the reduction of reflection at the reflection point. The retarder has a retardation value of from about 220-320 nm according to certain embodiments, and is a 1/2. lambda. retarder according to preferred embodiments.

US Classification:

349120

Abstract:

A multi-colored pixel for a twisted nematic liquid crystal display including red, green, and blue subpixels, wherein each subpixel includes a pair of substrates, a pair of polarizers, opposing electrodes, and a color personalized retardation film which compensates for the different wavelength of each color. The personalized retardation films of the different color subpixels results in elimination of the multi-gap approach and substantially eliminates the problem of different color leakages at different viewing angles, including normal. Also, one polymer based element, preferably a polyimide, functions as both a color filter and a retardation film in certain embodiments of this invention.
