Officials of JPSA Laser in Hollis, N.H., are introducing the IX-1000 ChromaLift excimer-laser system for LED lift-off applications for the compound semiconductor and wafer fab industries. A major cost of LED fabrication is the sapphire and the scribe-and-break operation and LED liftoff dramatically reduces the time and cost of the LED fabrication process by eliminating wafer scribing by enabling the manufacturer to grow Gan LED film devices on the sapphire wafer, then transfer the thin-film device to a heat-sink electrical interconnect. The IX-1000 ChromaLift homogenizes the laser beam profile and fires through the back of a sapphire wafer to debond the GaN LED device and transfer it to a substrate where it can then be packaged onto a heat sink and/or optical reflector. It is capable of large area per shot of areas as large as 1 by 1 centimeters; 5 by 5 millimeter to as many as 100 sites per second; and 3 by 3 millimeters to as many as 200 sites per second.

Officials of UDT Sensors in Hawthorne, Calif., are introducing the UV-SPOT segmented-photodiode position-sensing detector for targeting and guidance systems. The device is a substrate photodiode that is segmented into four active areas. Available with a 0.005-inch gap between elements, the device is for nulling or centering applications. The device attains position information by using the segmented sensor when the light spot diameter is larger than the spacing between the cells. The UV-SPOT is for applications that use the spectral range of 200 to 1,100 nanometers, including machine-tool alignment, beam centering, surface profiling, and position measuring.

Clearview unveils direct-bonding process to enhance flat-panel displays

Click here to enlarge image

Clearview Displays LLC in Beaverton, Ore., is announcing G-Bond, an optical enhancement process for flat-panel displays that optically bonds display cover glass and touch-screens directly onto the .. front of a thin-film-transistor liquid-crystal display (TFT LCD) to increase contrast and brightness. Clearview officials say G-Bond can enable LCDs to become daylight- and sunlight-readable without significantly increasing the backlighting of the display. The optical nature of the bond eliminates most of the surface reflection on the display, which often is the source of image washout. Directly bonding cover glass to the surface of an LCD also creates a protective shield to prevent breakage, company officials say.
