Abstract:
A light emitting device includes a substrate having a first surface and a second surface not parallel to the first surface, and a light emission layer disposed over the second surface to emit light. The light emission layer has a light emission surface which is not parallel to the first surface.
Abstract:
A method for fabricating a micro structure includes depositing a first layer of a first material over a substrate; patterning a first hard mask over the first layer; depositing a second layer of a second material over the first layer and the first hard mask; patterning a second hard mask over the second layer; and selectively removing the first material and the second material not covered by any of the first mask and the second mask to produce over the substrate the micro structure having a first structure portion having a first height and a second structure portion having a second height.
Abstract:
A high contrast spatial light modulator for display and printing is fabricated by coupling a high active reflection area fill-ratio and non-diffractive micro-mirror array with a high electrostatic efficiency and low surface adhesion control substrate.
Abstract:
A micro mirror device includes a hinge supported by a substrate and a mirror plate tiltable around the hinge. The hinge includes a length longer than 1 micron, a thickness less than 500 nanometers, and a width less than 1000 nanometers. The hinge can produce an elastic restoring force on the mirror plate when the mirror plate tilts away from an un-tilted position.
Abstract:
Methods and apparatus for providing a high-resolution spatial light modulator. A spatial light modulator includes a cell that includes: a substrate portion; a first support post and a second support post, each having a top surface; and a micro mirror that includes a hinge member having a first end and a second end. The first end and second end is secured to the top surface of the first support post and the second support post, respectively. The hinge member and the support posts are completely hidden underneath the micro mirror.
Abstract:
Methods for driving a plurality of MEMS devices in an apparatus are described. A voltage pulse is applied to an electrode or a structure portion of a MEMS device. The electrode is on the substrate underneath the structure portion. At least two MEMS devices of the plurality of MEMS devices have different threshold voltages, and the threshold voltage is the minimum voltage required to move the structure portion. A bias voltage is applied to whichever of the electrode or the structure portion of the MEMS device does not have the voltage pulse applied thereto. The bias voltage and the voltage pulse are capable of moving the structure portion of the MEMS device that has the higher threshold voltage of the different threshold voltages.
Abstract:
A method for applying anti-stiction material to a micro device includes encapsulating a micro device in a chamber, vaporizing anti-stiction material in a container to form vaporized anti-stiction material, transferring the vaporized anti-stiction material from the container to the chamber, and depositing the vaporized anti-stiction material on a surface of the micro device.
Abstract:
A display system includes one or more rows of tiltable micro mirrors, each of which is configured to be selectively tilted to an “on” position to reflect incident light in an “on” direction and to be selectively tilted to an “off” position to reflect incident light in an “off” direction; an optical projection system configured to project light reflected by the micro mirrors in the “on” direction to produce one or more first lines of image pixels along a first direction in a display image and to change the direction of the light reflected by the micro mirrors in the “on” direction to produce one or more second lines of image pixels in the display image and a light source to produce the incident light. The one or more second lines of image pixels are substantially parallel to the one or more first lines of image pixels.

Abstract:
Apparatus having a plurality of temperature sensors (probes) positioned at a number of locations upon a platform such as a placebo or dummy wafer and a method of fabricating and using the apparatus. The temperature sensors are photoemissive temperature sensors. To fabricate each of the photoemissive sensors, a thermally conductive epoxy is placed in a mound at each sensor location upon the platform. Upon one side of this mound, a coating of phosphorous material is applied. One end of a fiber optic cable abuts the phosphor material, and a an encapsulation layer such as a polyimide tape is positioned atop the conductive epoxy and the fiber optic cable such that the fiber optic cable is maintained in a stationary position relative to the phosphor material to obtain a local temperature of the wafer surface.
