Seoul Semiconductor has 5,500 patents, including Acriche product-related technologies, to operate multiple light-emitting cells with AC power, lights the patented Acriche technology of connecting multiple lights cells in a single chip allows for both AC and high voltage DC operation, simplifying operation in many applications including backlighting of LED TVs and solid state lighting.
Brian Wilcox, Vice President of North American sales for Seoul Semiconductor, said, “The ZEBRAlliance project marks the beginning of a new era in home lighting. The United States Congress has mandated elimination of ordinary incandescent bulbs by 2014; Europe did the same last year, banning the sale of incandescent bulbs over 100 watts. This market will grow substantially as consumers realize the benefits of brighter illumination combined with energy efficiencies.”
He added, “Seoul’s participation in this project shows our determination to continue proliferation of this technology and solidify our position as a market leader”.
ZEBRAlliance, An Alliance Maximizing Cost- Effective Energy Efficiency in Buildings, is both a public-private research project and a multi- faceted energy-efficiency education campaign. The founders of the public–private alliance include Schaad Companies and Oak Ridge National Laboratory along with Tennessee Valley Authority, the Department of Energy, BarberMcMurry Architects and many industry partners. The ZEBRAlliance currently has four energy efficient homes under construction in the Wolf Creek Subdivision in Oak Ridge, TN.
MMICs Update Predicts a Decrease in InGaP and InP Markets
According to Research & Markets’ latest report, GaN and SiGe will overtake the GaAs MMIC sector while InP and InGaP demand in MMICs will dwindle.
Research and Markets has announced the addition of the “The MMICs Update Report (MMICs2)” report
70
www.compoundsemiconductor.net October 2010 to its offerings.
This report is an update following Engalcos first report on the (compound semiconductor) MMICs industry which was released in summer 2008.
The most important resource by far is the regular contact maintained by a mixture of telephone, e-mail and physically meeting appropriate industry executives the majority of whom are well known to the authors. Beyond this the authors also naturally make substantial use of various web sites both corporate and otherwise.
In the report, the authors refer to developments in microwave frequencies (between 700 MHz and 20 GHz) and “millimeter-wave” frequencies (above 20 GHz). The higher microwave frequencies, notably “X-band” (8.2 to 12.4 GHz), and Ku-band (~12.4 to 18 GHz) are of particular importance in both military and satellite applications. The Ka-band (26.5 to 36 GHz) is increasingly significant in new satellite configurations.
The report points out that many of the new and proposed systems implement combinations of both Ku-band and Ka-bands. MM-wave has generally become increasingly important in EW seekers. ICC modules use mm-wave technology and it is predicted in the report that in 2013, the 79 GHz band will become the dominant specification.
The great majority of “pure-play” and fabless players are headquartered in the U.S., which is also the economy with the largest markets for most of the MMIC products considered. Exceptions are cell phones and certain other “commodity” products that are manufactured mainly in Europe (e.g. Nokia) or the Pacific Rim (“RoW”), notably and increasingly China (e.g. Huawei, ZTE).
The authors identified a total of 67 MMIC players addressing these markets. Although most of the players are “pure-play” , they mention Hittite Microwave and Mimix Broadband as the two of the most prominent of the fables MMIC companies.
A relatively large number of companies offer GaAs MMICs. In some ways this is historical; GaAs was the first compound semiconductor material to enter the RF/microwave scene and has essentially been available as a MMIC substrate since the 1970s. Currently the markets for GaAs MMICs dominate
