The issues of TDR resolution are often misunderstood or misrepresented, because the TDR resolution is believed to be completely governed by the following rule of thumb. Two small discontinuities, such as two vias in a PCB, can still be resolved as two separate ones, as long as they are separated by at least ½ the TDR rise time:

Through our U.S. affiliate, Samsung has been cooperating actively with the U.S. department,” a Samsung spokeswoman was quoted as saying in the report. We are sincerely cooperating with (U.S. investigators),” the report quoted a Hynix official as saying.

The report quoted Dongwon Securities analyst Micheal Min predicting that Hynix could be hit with fines of 200 billion won (about US$174 million) or above, an amount equivalent to one-tenth of Hynix's full-year operating profit.

It's hard to tell what the investigation will end up with. If Hynix gets an unfavorable ruling, this should hurt its (earnings), but any impact will be short-lived and limited,” the report quoted Min as saying.

But the Infineon guilty plea could reverberate around the industry and start and avalanche.

BANGALORE, India — India, the favored destination for the outsourcing of software development, is also attracting outsourced research and development projects, according to a new study.

The study by Research and Markets of Ireland found that R&D outsourcing to India will grow from $1.3 billion in 2003 to $8 billion by 2010.

Growth in R&D outsourcing has been boosted bythe outsourcing of services. Now, overseas companies that used India as a low-cost base are beginning to exploit Indian technical expertise.

As many as 150 R&D centers have been established in India. Texas Instruments Inc. led the way in 1985, followed by Intel, Motorola, IBM and Cisco. Recently, Advanced Micro Devices indicated it will design and develop a new processor from its center here.

In India, R&D outsourcing existed even before'outsourcing' became a fad,” the researchers said. Outsourcing models for R&D vary — from captive to thirdparty to contract assignments — and the pioneers arefrom the information technology industry, Research and Markets said.

De même, les « qutons » ou « bits quantiques sur un photon » de Yale pourraient permettre d’intégrer des ordinateurs quantiques sur des semi-conducteurs bien plus tôt.

Parmi les avantages de la méthode élaborée à Yale, on peut citer la taille relativement petite de ses référentiels bits quantiques (environ un µ² ) et la capacité de lire l’état d’un bit quantique sans le perturber, le plus gros problème actuellement pour les ordinateurs quantiques.

L’approche de Yale consiste à stocker des bits quantiques dans une boîte de Cooper contenant plus d’un milliard d’atomes d’aluminium supraconducteurs en interaction, entraînant ainsi une sorte de dynamique quantique qui permet à un photon « de contrôle » de lire l’état d’un bit quantique dans la boîte de Cooper sans en modifier l’état.

Selon les chercheurs, les recettes qu’ils ont élaborées pour les circuits d’informatique quantique reposant sur l’électrodynamique quantique pourraient susciter une vague d’expériences en laboratoire. Bientôt, ajoutent-ils, des expériences viseront à tester les circuits quantiques afin de développer de nouveaux circuits destinés à l’optique et des photons capables d’interagir sur puce avec des circuits électroniques traditionnels.

MURRAY HILL &#151 Einem gemeinsames Entwicklerteam der berühmten Bell Labs und des niederländischen Halbleiter-Ausrüsters ASML ist ein viel versprechender Durchbruch in der maskenlosen Lithographie gelungen. Möglicherweise kann die Technologie schon bald in der Chip-Produktion eingesetzt werden.
