Scientist Dr. Bernd Heinemann of IHP – Innovations for High Performance Microelectronics will present results on silicon-germanium heterobipolar transistors (SiGe HBTs) developed in Frankfurt (Oder) on the “International Electron Devices Meeting” (IEDM) in San Francisco. His contribution titled “SiGe HBT with fT/fmax of 505 GHz/720 GHz “ presents speed parameters that set new standards for silicon transistors.
“To present at IEDM is a valuable conclusion of the project ‘DOTSEVEN’, funded by the European Union. Together with Infineon and twelve other project partners from a total of six countries, the four-year project focused on developing SiGe HBTs with a maximum oscillation frequency, which is also referred to as fmax, of 0.7 THz,” says Dr. Bernd Heinemann, project manager at IHP.
“The presented fmax values exceed the best values of current production technologies by a factor of two. Such transistors enable the realization of wire-bound and wireless communication systems with even higher data rates (> 100 Gb/s).
With the fast HBTs the performance of radar systems, such as in personal cars, can be increased by reducing power consumption or increasing range and spatial resolution.”
In addition, the application becomes a reality in numerous new applications, which until now have been inaccessible to silicon components and which have been reserved for, compared to silicon technologies, the less integration-friendly solutions of III-V compound semiconductors.
These newly emerging fields of application include imaging processes in the frequency range of 0.3 to 1 terahertz, which can be used for example for material testing, for safety inspections, for medical biopsies or for the detection of air pollution in the atmosphere.
It should be emphasized that these components are compatible with established silicon technologies. Thus, they are suitable as key elements for cost-effective systems in a broad market.
The International Electron Devices Meeting (IEDM) has been the world’s preeminent forum for reporting technological breakthroughs in the areas of semiconductor and electronic device technology, design, manufacturing, physics, and modeling for more than sixty years.
From December 3-7, 2016, leading scientists will present the latest research results to the international specialist audience.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
