Intel has submitted a business plan to upgrade its fab in Israel, according to reports. Crocus Nano Electronics (CNE), the joint venture founded in 2011 by Crocus Technology and Russia’s RUSNANO, has raised $60 million from its investors. The venture is Russia’s first 300mm fab. This first production line was completed one year after construction began. Currently, 200mm and 300mm CMOS wa... » read more

Amazing New Materials
By Michael Watts - 20 Mar, 2014 - Comments: 0

Materials are fundamental to active photonics devices, and there were plenty of developments discussed at Photonics West 2014. Element Six was happy to talk about progress in making large single-crystal diamond and even larger polycrystalline diamond wafers. Carbon has a number of stable forms; diamond, graphite, nanotubes and amorphous carbon. The Element Six process uses CVD conditions in ... » read more

The Week In Review: Sept. 23

By Mark LaPedus For some time, Apple’s iPhones have incorporated a separate RF switch and diversity switch from Peregrine Semiconductor (PSMI). The switches are based on a silicon-on-insulator (SOI) variant called silicon-on-sapphire (SOS). Murata takes Peregrine’s RF switches and integrates them into a module. Doug Freedman, an analyst with RBC Capital, said Apple is no longer using PSMI�... » read more

By Mark LaPedus Is China set to bail out a U.S. government technology darling? Two Chinese automotive companies, Geely and Dongfeng Motor, are reported to have bid between $200 million and $350 million for a majority stake in Fisker, the maker of plug-in hybrid cars. If that happens Fisker—which has $192 million in U.S. federal government loan guarantees—could be headed to China, according... » read more

Pyramids Are Not Just For Pharaohs

By Mike Watts There were 3 different applications for pyramid patterns this year at Photonics West in San Francisco; improved LED’s, improved absorbers and single quantum dot devices. This not the first time the ancients have come to the rescue of nano-technology, a couple of years ago we had nano-menhirs. Several groups talked about improving LED’s through pyramids. A Samsung team grew... » read more

LED Firms Mull New Wafer Sizes And Materials
By Ed Sperling - 16 Aug, 2012 - Comments: 0

By Mark LaPedus Seeking to reduce the cost of solid-state lighting and related applications, LED manufacturers are taking a page from the IC industry: They are looking at larger wafer sizes and new materials in the fab. Today, the state-of-the-art LED fab is a 150mm (6-inch) facility, but a large percentage of these plants are still using 50mm (2-inch) substrates. The vast majority of LED s... » read more

The GaN Plan
By Ann Mutschler - 08 Apr, 2010 - Comments: 0

By Ann Steffora Mutschler Given the need to control power in high-end market segments such as servers, notebooks, mobile handsets and wired communications equipment, the market for gallium nitride (GaN)-based chips is poised for explosive growth. Case in point: Server farms are using more and more electricity, and the cost of that power is getting to be a significant fraction of the operati... » read more
