Sun précise que les produits des deux sociétés sont complémentaires.

Nawotech's investors include Wellington Partners, CIPIO, Target Partners, and Intel Capital, it was noted.

Besides supporting Intel, the acquisition of Nawotec will further strengthen Carl Zeiss SMT's technology base in the area of nanostructuring and mask repair technology,” according to the German company.

It also aims to expand the company's semiconductor equipment business beyond lithography optics. Zeiss' claim-to-fame is being the sole supplier of optical lenses for lithography-tool vendor ASML Holding NV of the Netherlands.

Zeiss also sells mask defect and other tools as well. With the acquisition of NaWoTec, Carl Zeiss SMT is adding to its technology portfolio excellent application know-how of mask repair processes, highly flexible application software allowing easy adaptation for further applications, and computer controlled gas injection hardware to precisely control chemical reactions,” said Hermann Gerlinger, president and CEO of Carl Zeiss SMT, in a statement.

NaWoTec's operations will be closely integrated with the Semiconductor Metrology Division of Carl Zeiss SMT. The transaction is expected to close during the second quarter of 2005.

Zeiss faces an uphill battle in the mask repair market, as too many vendors are chasing too few dollars in the arena, according to analysts (see Oct. 11, 2004 story). At the same time, new tools based on e-beam and nanomachining technologies are coming to the mask repair market, complementing traditional tools based on focused ion beams and lasers.

Rival mask repair tool vendors FEI Co. and SII NanoTechnology have separately entered the e-beam market with combination or standalone systems. Nawotec entered the mask repair market with an e-beam tool in April and counts Intel as an early customer. And Rave LLC is pushing mask repair tools based on a nanomachining” methodology.

Sunnyvale, Calif.&#8212Supertex touts its patent-pending hysteretic current-mode control in the company's HV9930 buck-boost LED driver IC as central to fast transient response without the need for complex loop compensation and external components. Working from an 8-200 volt input, this variable-frequency PWM chip, which controls the LED's driver stage, is suited to automotives, AC/DC low-voltage applications, and general RGB backlighting.

The HV9930 uses hysteretic current control to regulate both the input and output currents in order to achieve the aforementioned gains in loop response and component-count economy. Input-current control also secures current-limiting during startup and for output overload conditions.

Asked about overall progress on k, the panel largely agreed with Jan's assessment: We are only going to see about ten percent improvement in the effective value of k per node. That's reality,” he stated.

Wisnieff countered that if the gain was only going to be ten percent, they would have to get much better at controlling variations. Controlling variability will make the designer give back everything you've gained in effective k,” he said.

Chen discussed how designers might cope. Local routing is going to be OK,” he stated. For global routing, you are going to have to relax the dimension rules to manage RC. But then there's the problem of lots of I/O. If you have relaxed layout, high I/O density means lots of vias — and that means lots of delamination-related reliability issues.”

Warren, N.J. —ANADIGICS, Inc. reports that it has introduced new digital and analog tuners that provide RF front-end functionality in the industry's smallest package size. The AIT1010 and AIT1021 devices are optimized for performance and space savings in cable and terrestrial broadband tuning applications, including digital television (DTV) and high definition television (HDTV).
