Los Alamos researchers point the way to more efficient harvesting of solar radiation

SAN JOSE, Calif. — Japan's fab tool and materials suppliers are seeing tough times.

Fab tool giants Advantest, TEL and others have recently reported bad news. Japanese tool maker S.E.S. Co. Ltd. filed for bankruptcy protection under a rehabilitation law. And amid losses, Tokyo Seimitsu Co. Ltd. has recently exited the wafer inspection business.

The book-to-bill ratio for Japanese fab tool vendors was 0.55 for January, down from 0.70 in December, according to the Semiconductor Equipment Association of Japan (SEAJ).

It's also a bad picture on the materials side. Silicon wafer vendor Sumco Corp. this week posted lackluster results. And Japanese and U.S. photomask makers face a contraction in 2009.

Citing the downturn, Sumco posted sales of 391.9 billion yen ($3.99 billion) for its fiscal year, down 17.6 percent over its previous year. Net income was 18.8 billion yen ($191.3 million), down 74.8 percent.

In another bad sign for Japan's materials vendors, the semiconductor photomask market fell by 12 precent in 2008 after a 2 percent drop in 2007, according to The Information Network, a New Tripoli, Penn.-based market research company.

''The market will drop another 11 percent in 2009, with the high-end photomask market (less than 90- nm) dropping 18 percent, while the low-end market will be flat,'' said Robert Castellano, president of The Information Network.

In 2008, Japan's Toppan led the worldwide merchant mask market with a 35 percent share, down from a 39 percent share in 2007. Japan's DNP followed with a 34 percent share, up from a 32 percent share in 2007.U.S.-based Photronics gained 1 share point last year, according to the firm.

SAN JOSE, Calif. — Embedded processors and connectivity chips are bright spots in a semiconductor market that will see double-digit dips in computer and cellular chip sales in 2009, said Mario Morales, vice president of global semiconductor research at International Data Corp.

Standard impedance is 50 ohm and attenuation values to 30 dB are available including 0.5 dB increments. Achievable VSWR is 1.3:1 to 12 GHz depending on implementation and attenuation accuracy starts at ±0.2dB. These attenuators are especially suited, but are not limited to, RF and microwave applications.
