On to Pastures New – European Researchers Develop Simulation Models for Extra-Functionality CMOS Devices

Process simulation in semiconductor industry has been brought to a state which allows the sufficiently accurate prediction of important electrical characteristics of core devices in advanced CMOS technologies. Today, the use of TCAD (Technology Computer Aided Design) is an inevitable part of device and process design as it implies a reduction of development costs and duration by about 30 – 40 %.

However, concepts towards low-power electronics, smart power applications, CMOS image sensors, and CMOS derivatives providing extra functionalities are still not sufficiently supported by TCAD. This especially concerns the prediction of leakage currents caused by electrically active defects and alternative doping techniques like plasma immersion ion implantation, low-temperature implantation, diversified cocktail implants, and laser annealing, which are considered for low-leakage ultra-shallow junctions.

The lack of suitable models that can be used in the early stages of industrial R&D inhibits the necessary cost reduction in the development of devices in a field where Europe is still at the forefront. Therefore, the recently launched European project ATEMOX (Advanced Technology Modeling for Extra-Functionality Devices) will develop the full set of missing models and implement and include them into the Sentaurus TCAD platform, an industrial standard software, so that they are of immediate value to the European semiconductor industry. The integrated models will finally be evaluated with respect to industrial needs.

To reach these ambitious goals, a consortium of European companies active in complementary fields of competence and leading European research institutes has been formed, which covers all necessary fields of competencies from experiment via characterization and modeling to simulation.

On July 21, 2010, coordinator Fraunhofer IISB in Erlangen, Germany, hosted the kickoff meeting for the 3-year project, which has a total budget of 4 million Euro.

ATEMOX is funded by the European Union in the 7th Framework Programme, under the ICT project number 258547.

Im Focus: Novel light sources made of 2D materials

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.

So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Im Focus: Light-driven atomic rotations excite magnetic waves

Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
