<p>Qualcomm has faced legal actions over its alleged extraction of exorbitant royalties for CDMA technology used in second- and third-generation cellular chips and systems. By contrast, a WiMax Forum executive said no one company holds a corner on the patents behind WiMax. Those 1,550 patents are held by 330 companies, and three-quarters of the ones with more than 10 patents are already WiMax Forum members, according to an analysis done by the group.</p>

In addition, the high-performance line scan products offer high sensitivity from deep UV (193 and 248 nm) to the visible band (400 to 700 nm), and a dynamic range of greater than 1500:1 for a higher measurement range in each field of vision.

One of the things I'm most excited about is the breadth of this relationship,” Ballmer said. We're the only companies whose road map really talks about this notion of the smart, unified client.”

Tying together multiple technologies for deployment on a single server to simplify administration is one of the alliance's goals. UC Integrated Branch, a new product scheduled for release at the end of 2007, will link VoIP functionality with Microsoft's communications tools for deployment on a single server. Another planned offering, a unified conferencing solution, will combine Nortel Multimedia Conferencing with Microsoft's Office Communicator 2007.


Deeper integration of Microsoft's software with Nortel's telephony products throughout the vendors' portfolios is a pillar of the partnership, which Microsoft and Nortel are calling the Innovative Communications Alliance (ICA).

Key customers like Royal Dutch Shell contributed to the alliance's formation by urging the companies to work together, according to Ruchi Prasad, Nortel's ICA general manager.

Listening to the customers is apparently paying off. Johan Krebbers, an IT architect at Royal Dutch Shell, took the stage at the event to describe how his 11,000-employee company is gradually replacing its heterogeneous communications infrastructure with one built entirely around a Microsoft/Nortel unified communications system.


Microsoft and Nortel have opened 27 joint demonstration centers in North America, Europe and Asia to tout their unified wares, with 100 more centers scheduled to open by the middle of this year.

The demo centers are used only for direct-sales pitches, but executives said partners are participating in proof-of-concept workshops at two ICA Collaboration Centers, one in Raleigh, N.C., and one in Maidenhead, U.K., near London.


We're going to be leveraging very extensively our ecosystem of partners,” Zafirovski said.

Though Nortel executives frequently invoked references to the partner channel, the company is also looking to grab a big chunk of the unified communications services business for itself.

The researchers used a highly focused ion beam that enables them to deposit the ion material into a substrate. The material can be injected” into the substrate with a depth of up to 50 nanometers and then, in a second process step, be used as a seed crystal for creating a nanowire. With this process, we can exactly determine the position and length of the nanowire”, explained Lothar Bischoff from the Institute of Ion Beam Physics and Material Research at the Rossendorf Research center.

As a substrate, the researchers used thin silicon wafers that were vaporized with cobalt. Then, the wafers were annealed in order to allow the cobalt atoms to diffuse evenly into the silicon material. The Rossendorf researchers succeeded in creating nanowires made of different materials – gallium, gold, or platinum. Presently, the researchers can grow nanowires with lengths of up to 10 microns and a thickness of up to 20 nanometers. These nanowires feature properties to transport electrical current similar to metals like aluminum or copper. But, as Bischoff explains, while copper metal layers in semiconductors need to be equipped with an insulating” layer around it that keeps the copper atoms from diffusing into the semiconductor, the nanowires do not require such precautions. According to Bischoff, it is even possible to implement a Schottky junction between nanowire and the semiconductor, which would enable chip designers to create very fast light detectors.

Possible industrial applications of the technology are not restricted to the transport of electrical current, explained Bischoff – the nanowires can also be implemented in a way that they transport light. This property could be utilized for the implementation of opto couplers or integrated opto-electronical circuits.

However, industrial applications are about two years away, explained Bischoff. No specific industrial project is in sight. But of course we are in close contacts with the local semiconductor companies in the Dresden area”, Bischoff said.

For the Chongqing project, the clean room should be finished by the end of this year. Mass production will begin in the second quarter of 2008. The planned capacity is 60,000 wafers per month. ProMOS will buy new equipment for the first 20,000 wafers, and then transfer used equipment from a fab in Taiwan for the rest. Initially, ProMOS will use 0.25 micron design rules and then migrate to more advanced technology as the fab reaches full capacity by 2009.
