Europæisk projekt med fokus energieffektive chips til hårde miljøer

ATHENIS er er navnet på et netop afsluttet fælleseuropæisk projekt, hvor der er fokuseret på udvikling af energieffektive chips til bl.a. automotive applikationer (in english).

On behalf of the ATHENIS project consortium austriamicrosystems, a leading provider of high performance analog ICs, announces the successful completion of the EU FP7 project ATHENIS (Automotive Tested High Voltage Embedded Non Volatile Memory Integrated System On Chip)

Currently more than 20% of the value of each conventional (ICE) car already comes from embedded electronics. This will further increase for hybrid (HEV) and fully electrical vehicles (FEV). Keeping costs and space for additional functionality low requires integration of low voltage and high voltage devices and embedded memory on a single System-on-Chip (SoC). Increasing energy efficiency of vehicles also requires placing ICs in harsh environments e.g. near batteries, motors, or alternators while keeping costs low in order to ensure broad market adoption.

ATHENIS has for the first time demonstrated a manufacturing technology platform for IC operation for the combination of harshest environmental conditions known in the automotive industry. This includes full reverse polarity capability at the low cost of CMOS, application voltages up to 120V, currents up to 10A, temperatures up to 200°C, embedded non-volatile memory, chip-level ESD up to >8kV HBM, and high logic gate densities. 

The capabilities of the technology platform were demonstrated by a novel 'flexible' alternator regulator IC enabling a new generation of alternators with 1-2% reduction in fuel consumption and CO2 emissions for ICEs and HEVs.

The consortium led by austriamicrosystems (AT) included Valeo Powertrain and Electrical Systems (FR), Cavendish Kinetics (NL,UK), Fraunhofer IISB (DE), TU Vienna (AT), University of Ferrara (IT), MASER Engineering (NL) and Fondazione Bruno Kessler (IT) as partners, all of them leaders in their respective areas of expertise.

The ATHENIS technology platform was established by combining HVCMOS technology from austriamicrosystems with MEMS-based "Nanomech" embedded non-volatile memory technology from Cavendish Kinetics. System specifications and verification including validation of operation up to 200C in a retrofitted commercial car was contributed by Valeo Powertrain and Electrical Systems.

Development of novel reliability, simulation, characterization and testing methods as well as new ESD and device concepts were performed by the other partners. The resulting technological advances of ATHENIS led to 14 patent filings and 35 publications. Academic highlights that have received international recognition include a novel, predictive NBTI reliability model (invited paper at IEDM 2010) and the first report of a 0.18µm HVCMOS technology with operating voltages up to 120V and 8kV HBM ESD (ISPSD 2010).

- The mastering of IC reliability for harshest environments in the ATHENIS project has not only enabled a new generation of flexible alternators for reducing CO2 emissions, but also provides the basis for further integrated electronics to improve energy efficiency and reduce costs in cars even for Fully Electrical Vehicles of the future, states Mr. Jean Claude Matt, Advanced and Generic R&D Director from Valeo Powertrain and Electrical Systems, who has chaired the ATHENIS Steering Committee.

- As result of ATHENIS we have been able to introduce low cost HVCMOS technology and reliable embedded non-volatile memory to applications in harshest automotive environments and gained substantial scientific insights into reliability phenomena. The project results hold the promise of significant commercial success for the industrial partners as well as contributing to CO2 emission reduction as outlined in the EU 2020 initiative, adds Martin Schrems, Director Process Development & Implementation at austriamicrosystems, who has led the coordination team of ATHENIS.
