15 Years Infineon

Global Challenges in Focus

Semiconductors have revolutionized our day-to-day lives, paving the way for ground-breaking innovations as diverse as smart phones, electric cars and renewable energy. Infineon Technologies, continuing in the tradition of Siemens, plays a defining role in advancing today's semiconductor technologies. Join us on a journey through our company history. It all started out in a castle in Upper Franconia.


Once upon a time at a small castle in Pretzfeld...

In 1946, the Siemens Executive Board establishes a lab dedicated to basic semiconductor research at a small castle in the village of Pretzfeld. In the summer of 1946, a small group of researchers starts work there, laying the foundations of Infineon Technologies as we know it today. The group is headed by Eberhard Spenke and includes Walter Schottky as a scientific consultant - two pioneers in semiconductor research.

In 1951, Heinrich Welker registers a patent for DE970420B, an electronic semiconductor device that forms the basis of all III-V semiconductors. This class of semiconductors includes gallium and arsenide and is used in a wide range of components, including light emitting diodes (LEDs). Today, lighting remains a key application area for semiconductor modules from Infineon.

IR relocates from original facility on Victoria St. In Inglewood to1521 Grand Ave. in El Segundo.


Semiconductors take center stage as Siemens establishes semiconductor fabrication facility

April 1, 1951, an internal memo announces Siemens' plans to open a semiconductor fabrication facility. In the letter, Ernst von Siemens writes: "semiconductors such as transistors, thermistors, varistors and diodes (crystal diodes) are becoming increasingly important in communications engineering. This is an extremely important area and it is therefore vital that we establish a strong presence across the entire field." Today, Infineon has a dozen fabrication sites worldwide. Half of these are located in Europe.

The Villach site is also responsible for the international business development of five Infineon product lines focused on energy efficiency and electric mobility. Over the decades, Infineon Technologies Austria AG has become a leading light in Austria. Today, around 3,100 employees from around 60 different nations work at our sites in Villach, Klagenfurt, Graz, Linz and Vienna.

The cutting-edge chip production facility is completed in record time, with the new facility ready for equipment in just nine months. 2,000 employees work at the site, using complex fabrication technologies to produce high-quality chips based on 200mm silicon wafers. Since 2011, work has been underway on the world's first high-volume facility for the production of power semiconductors on 300mm silicon wafers at Dresden.

Today, around 1,750 people are employed at the site, which encompasses backend production of IGBT modules and frontend fabrication of bipolar chips. These products are primarily used in renewable energy (wind, photovoltaics, etc.), industrial electrical drive and transport (high-speed trains, underground trains, trams, etc.) applications.

The CoolMOS™ transistor is an evolution of the SIPMOS™ transistor. Thanks to an innovative technology, it reduces on-resistance - one of the key performance indicators of a transistor - by a factor of five. This means that less heat is generated when the transistor is in use, something that the product name CoolMOS™ clearly reflects. Devices consume less energy if they remain cool when in use. And more often than not, it's an Infineon chip that is hard at work keeping temperatures down.

Let there be light

Lighting accounts for around 20 percent of global energy consumption. However, the lighting market is still dominated by the 100-year-old light bulb. A conventional light bulb converts around 95 percent of electrical energy into heat and just five percent into light. LEDs are a more effective alternative. Unlike light bulbs, however, LEDs cannot be connected directly to a 230-volt AC grid. This means that the mains voltage has to be efficiently converted. This can be done using a combination of chips such as power transistors, power ICs and LED drivers from Infineon. These all control a range of different factors including energy consumption. They also ensure that LEDs are 80 percent more efficient than light bulbs. An LED lasts around 30,000 operating hours, compared with just 1,000 hours in the case of a typical light bulb. Infineon is committed to making lighting more efficient.

Turning a cellphone into a wallet

There are many different cash-free payment functions and applications that can be integrated into the latest generation of cellphones, including vouchers, travel tickets and payment cards. All of these transactions require stringent security standards. By delivering components for these standards, Infineon plays a key role in making mobile payment more secure.

Supporting the transition to a cleaner energy landscape

More and more wind parks are being built out at sea. These offshore sites have to be connected to power grids on land. High-voltage direct current (HVDC) transmission systems can be used to transport electrical energy efficiently over long distances. Infineon's 4.5kV IGBT modules play a key role in these systems.

IR introduces a highly innovative 600V automotive grade IGBT platform, COOLiRIGBT™ for electric and hybrid electric vehicles.

An invisible hand

Infineon's new 3D imaging sensor chips enable operators to control computers and electronic devices with their gestures - in other words, without actually touching the device in question. The chips control an external infrared light source and, when the reflected light returns, measure the phase shift between the emitted and reflected light. This enables them to deliver 2D information on each of the sensors' image points. The chips also provide information on distance and depth. The sensors enable devices to trace finger movements and hand gestures quickly and reliably.

Shaping the future of electric mobility

BMW and Infineon worked closely together to develop the BMW i3 electric car. Seventy-five semiconductors keep the electric drive running highly efficiently. These include the AUDO Future microcontroller, the HybridPACKT 2 IGBT power module and CoolMOS™ high-voltage MOSFETs. Infineon components are installed in the airbags, windscreen wipers and LED light modules.

Infineon makes smart wearables secure

A new trend is conquering wrists: Watches are becoming fitness trainers. But Sharkey from Watchdata Technologies can do even more: Sharkey is one of the first product families on the market that also enables touchless payments or electronic ticket purchases – as securely as with a chip card. At its core, Sharkey carries a security chip from Infineon that makes mobile devices NFC-enabled and at the same time reliably protects the user’s data.


Moving safely through night and fog

No matter how low the visibility is – with radar systems in the 77-GHz range, vehicles “recognize” other road users at a distance of up to 250 meters. The car warns the driver in case of danger or brakes automatically; up to now, this has been a privilege of premium vehicles. Infineon is developing new housing technology and manufacturing sensors with silicon-germanium technology. This will make the lifesavers affordable for other vehicle classes as well. With resounding success: In 2015, Infineon has already delivered the ten-millionth radar chip for cars and is nominated for the prestigious Future Award by the German Federal President.

Exclusive photos: Paparazzi in space

After a journey of more than nine years, the spacecraft New Horizons passed the dwarf planet Pluto at a distance of only 12,500 km on July 14, 2015. On board: more than 500 HiRel components. These have to deliver a flawless performance for years without maintenance while also resisting the cosmic radiation in outer space and braving temperatures of -270° C. As large as a grand piano, the spacecraft gave astronomers their first look at Pluto from such a short distance.

Infineon and International Rectifier: a powerful combination

In January 2015, Infineon takes over the US company International Rectifier Corporation for 3 billion US dollars. This consolidation gives Infineon additional system knowledge in the area of energy management and increases its expertise in power semiconductors. In addition, outstanding knowledge about compound semiconductors is being bundled, particularly about gallium nitride. By the end of the business year (September 30), International Rectifier has been integrated successfully; the company now has 35,400 employees.
