Infineon Ships Two Billionth Sensor Chip, Putting It Up With the World Market Leaders for Sensors Used in Automotive and Industrial Applications

Neubiberg, Germany – May 24, 2012 – Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) today announced it has shipped its two billionth sensor and thus belongs amongst the world’s leading providers of semiconductor-based magnetic sensors and pressure sensors. Infineon believes itself to be the world market leader in sensors for example for pressure sensors used in side airbag systems and for magnetic sensors used for wheel speed measurement in anti-lock braking systems, enjoying market shares of around 50 percent. In 2011, some 75 million vehicles were produced worldwide, around 20 million of these in Europe alone. Even today, Infineon delivers around four out of the some 20 magnetic and pressure sensors deployed on average in every new vehicle. This figure does not even include sensors used for tire pressure monitoring. Infineon is one of the few semiconductor manufacturers, whose sensor chips are represented in virtually all of the estimated 80 sensor applications in a vehicle, e.g. in safety, in the powertrain as well as in the body and convenience electronics. The company’s magnetic sensors are used for example in the electronic power steering, the gearbox control and in convenience functions such as electric windows. Its pressure sensors, which already incorporate the latest side airbag standards PSI5 and AK-LV 29, are used above all in side airbags and in the engine management system, not to mention in emerging applications such as pedestrian protection. Infineon’s product range of magnetic and pressure sensors is amongst the broadest on the market. In terms of industrial applications, Infineon focuses on sensors used in drives, smart metering and household appliances. “One of our key areas in sensor innovation is the combination of the sensing element with signal processing on one piece of silicon, thus making our sensors increasingly more reliable,” said Frank Findeis, Marketing Director, Integrated Sensors at Infineon Technologies AG. “In conjunction with our wealth of experience and high level of quality, this makes us the sensor partner of choice for automotive and industrial electronics.” Technology leader for sensors Infineon is on its way to becoming the technology leader for sensors. This applies both to the wafer-level silicon technology, which is based on the full breadth of Infineon’s technology portfolio, as well as the sensing elements themselves. In the field of magnetic sensors, besides the Hall effect technology, magneto-resistive technologies are also gaining in significance, which include GMR (giant magneto-resistive resistance), AMR (anisotropic magneto resistance) and TMR (tunnelling magneto resistance) technologies. Infineon masters all of these. Even today, Infineon’s integrated GMR and AMR sensor solutions that require the command of ferromagnetic materials in the manufacturing process excel with their outstanding quality and the value for money they offer. “Mastering the use of nickel-iron alloys, for example, in the manufacturing process of the integrated sensors, equates in fact to a small technological revolution similar to the introduction of copper metallization in the semiconductor manufacturing process,” said Frank Findeis. “The fact that we have succeeded here with our sensors is testimony of Infineon’s exceptional innovative energy.” Further information Click on the following links for further technical information on sensors and other semiconductor solutions from Infineon: www.infineon.com/sensors and www.infineon.com/automotive Infineon is presenting its sensors at the Sensor + Test exhibition and conference (May 22-24, 2012, Nuremberg, Germany) at booth 238 in hall 12.
