10-inch Sapphire Substrates

Monocrystal (Stavropol, Russia) has introduced ultra-large 10-inch c-plane epi-ready sapphire substrates. The LED industry continues shifting to larger diameter substrates as it strives to achieve higher cost savings and to increase production throughput of quality LED chips. Sapphire substrates are used for more than 90% of GaN LED chips produced by the industry, including high-brightness devices used for LED lighting products.

Projection Exposure System

The UX4-LEDs projection exposure system from USHIO America, Inc. (Cypress, CA) is for manufacturing LED chips. The system allows full-field exposure of 6-inch wafers while preventing wafer warpage or distortion — achieving a throughput enhancement of 300% compared with conventional stepper systems. It requires neither mask replacement nor cleaning that would cause system downtime, and allows enhancement of detection accuracy of alignment marks with low visibility, such as those for transparent electrodes, to achieve high overlay accuracy. A modular structure for major system components allows easy specification changes or upgrading and easy maintenance.

Green Aluminate and Red Nitride Materials

Intematix (Fremont, CA) has introduced two LED phosphor families: green aluminate and red nitride materials that enable high-quality white illumination when applied to blue LEDs. The phosphor families meet the material requirements for display backlighting and general lighting applications by offering an improved color spectrum and excellent color rendering to LED lamps. Intematix applied its proprietary accelerated materials discovery and development process, C-MAT Synthesis™, to develop the green aluminate and red nitride phosphors.

Multiplexer

Bitwise Systems (Goleta, CA) has announced their new Model QMUX16X2 Multiplexer designed to permit test and measuring equipment to connect to many signals. QMUX can measure two selected signals at the same time. The multiplexer features 16 inputs and 2 outputs and can be powered and controlled by a single, full-speed USB 2.0 compliant port. The multiplexer uses low-power reed relays and a USB controller in a DIN rail mount enclosure. It is suited to single or differential signals less than 10 MHz. Because the QuickMux uses mechanical reed relays, you can use it as a de-multiplexer as well as a multiplexer. The de-multiplexing capabilities of the QMUX16X2 permits two input channels and can be connected to any of the sixteen output channels on a standard 40-pin IDC header.

Quarter Brick DC/DC Converter

FDK Corporation (Sunnyvale, CA) has introduced a new high power regulated quarter brick to its Sensei Series of isolated DC/DC converters. The FPQR48T5R050 converter provides 50 Amperes (A) of output current (250 Watts) with outstanding thermal performance. This converter is designed for Intermediate Bus Architecture (IBA) and Distributed Power Architecture (DPA) in telecommunications, WiMAX, data processing, computing, and storage applications that require a regulated 5V distribution bus. The FPQR48T5R050 converter operates from a 36 VDC to 75 VDC input and provides a tightly regulated 5 VDC output with an efficiency in excess of 92.5%. It is offered in a 2.30" x 1.45" x 0.555" (58.4mm x 36.8mm x 14.1mm) industry-standard quarter brick footprint and pin-out.
