The Infineon Technologies AG , based in Neubiberg ( Munich County ) is a listed ( IFX ) company's largest semiconductor manufacturer in Germany and one of the ten largest worldwide. Infineon offers semiconductor and system solutions with a focus on energy efficiency, mobility and security. The company is divided into the business areas Automotive , Industrial Power Control, Power & Sensor Systems and Digital Security Solutions. Infineon is the global market leader in semiconductors for the automotive industry and for power semiconductors. The company was formed in 1999 when Siemens' semiconductor business was spun off .

With around 41,400 employees, Infineon achieved sales of 8.029 billion euros in 2019 (end of September). The takeover of Cypress in April 2020 increased the number of employees to 47,100 and for 12 months (until March 31, 2020) total sales of 9.925 billion euros resulted.

Business activity and business areas

Activities by business area

After several restructurings, Infineon now comprises four business areas:

  • Automotive (ATV) : Infineon supplies semiconductor products for use in the drive train (engine and transmission control), comfort electronics (e.g. steering, damping, air conditioning) and in safety systems ( ABS , airbags , ESP ). The product portfolio includes microcontrollers , power semiconductors and sensors . In the 2019 financial year (end of September), the segment's sales amounted to EUR 3.503 billion.
  • Industrial Power Control (IPC) : The company's industrial division bundles power semiconductors and modules that are used in the generation, transmission and consumption of electrical energy. The fields of application include the control of electrical drives for industrial applications such as locomotives, machines or household appliances. The semiconductor components are also used in modules for renewable energy generation in solar and wind power plants as well as energy transmission and conversion. In the 2019 financial year, IPC achieved sales of 1.418 billion euros.
  • Power & Sensor Systems (PSS) : The PSS division combines the business with chips for energy-efficient power supplies and high-frequency applications. These are primarily used in consumer goods such as televisions, game consoles, PCs, mobile devices and in computer servers. PMM generated sales of EUR 2.445 billion in the 2019 financial year.
  • Digital Security Solutions : The DSS division supplies microcontrollers for SIM cards for mobile telephony, security chips for payment cards and access cards as well as chip-based solutions for passports, ID cards and other official documents. For example, Infineon is supplying a considerable part of the chips for the new German ID card . In addition, DSS develops solutions for applications with high security requirements such as pay TV , trusted computing and near field communication (NFC). The turnover of this division was 642 million euros in 2019.

The two divisions IPC and PMM were created by splitting up the Industrial & Multimarket division on January 1, 2011.

Activities by region

Infineon operates worldwide and also manages its activities through national subsidiaries: in the United States from Milpitas (California), in the Asia-Pacific region from Singapore and in Japan from Tokyo. Broken down by region, 32 percent of sales were achieved in Europe, including 15 percent in Germany, 12 percent in North America, 7 percent in Japan, 15 percent in the Asia-Pacific region and 34 percent in the Greater China region.

subsidiary company

The Danube Integrated Circuit Engineering GmbH & Co. KG (DICE) , headquartered in Linz focuses on the development of integrated circuits for radar systems in the automotive and industrial sector. ICs for mobile communication and navigation are also offered. Infineon has held a majority stake in DICE since 2000. Infineon has held 100% of DICE since 2019.

The Infineon Technologies IT Services GmbH was founded in 2004 and supervised by Klagenfurt from significant portions of the global IT Infineon. Infineon holds 100% of Infineon Technologies IT Services GmbH.

The Infineon Technologies Bipolar GmbH based in Warstein is a joint subsidiary of Infineon and Siemens for of 2007. Infineon holds 60% of the company and Siemens 40%.


Spin-off from Siemens

Siemens AG spun off Infineon in 1999 and then floated it on the stock exchange because the semiconductor industry's enormous capital requirements can best be financed through the stock exchange and Siemens' business was too cyclical . After the IPO, Siemens reduced its stake to below 50% through package sales in 2001 and sold the remaining shares in 2004 and 2006.


Infineon is a suitcase word and is made up of infinity (English for 'limitlessness') and aeon (Greek for 'life, eternity, infinity').


On May 1, 2006, Infineon spun off its memory division under the name Qimonda as an independent company with 12,000 employees. The new company was listed on the New York Stock Exchange (NYSE) in August 2006 . However, Infineon initially did not succeed in placing old shares. Instead, the entire issue proceeds went to Qimonda through the issue of new shares. In October 2008, Infineon held around 77.5 percent of all shares in the company. On January 23, 2009, Qimonda filed for bankruptcy at the Munich District Court and at that time was still majority owned by Infineon.

Immediately before taking over the collective bargaining agreement reached in Baden-Württemberg for the metal and electrical industries in Bavaria, Infineon left the Bavarian employers' association on November 13, 2008.

At the beginning of July 2009, Infineon and US investor Golden Gate Capital contractually agreed to sell its Wireline Communications segment for EUR 250 million. The newly created company traded as Lantiq . At the end of January 2011, the sale of the previous Wireless Solutions division to Intel, which was resolved in August 2010, was completed. The newly created company had around 3,500 employees and was henceforth called Intel Mobile Communications (IMC).

Infineon is one of the first supporters of the FIDO Alliance , which has been developing the Universal Second Factor (U2F) industry standard for generally applicable two-factor authentication since 2013 .

On August 20, 2014, Infineon announced that it would take over International Rectifier by the end of 2014 for a cash price of around three billion US dollars. The acquisition was finally completed on January 13, 2015.

In July 2016, Infineon announced its intention to purchase Wolfspeed, a subsidiary of Cree Inc. , for $ 850 million. This should strengthen the market presence in the area of gallium nitride on silicon carbide (GaN on SiC). Shortly before implementation, however, the takeover was classified as a national security risk and thwarted by the foreign investment approval committee of the new US administration under President Trump .

In October 2016, Infineon announced the acquisition of Innoluce BV. The semiconductor company, founded in 2010, develops micro-electromechanical systems (MEMS) in combination with miniature laser scanning modules, which are required for optical distance and speed measurement ( lidar ) for autonomous driving. A purchase price was not mentioned.

In May 2018, Infineon announced the largest single investment in its company's history. At the Villach location , 1.6 billion euros are to be invested in a semiconductor plant and research center. The CEO of Infineon Technologies Austria AG has been Sabine Herlitschka since 2014 , and Monika Kircher from 2007 to 2014 .

In June 2019 it was announced that Infineon is aiming to acquire Cypress Semiconductor Corporation for around 9 billion euros. This acquisition is the largest takeover in Infineon's history.

Conviction for illegal price fixing

In June 2002, the US Department of Justice launched investigations against Infineon and other DRAM manufacturers such as the South Korean corporations Samsung and Hynix after computer manufacturers complained about the increasing price of memory chips. In 2004, Infineon was the first of these companies to plead guilty to the US Department of Justice of having  harmed consumers - or computer manufacturers such as Dell , IBM, and Apple - through illegal price fixing for DRAM memory chips between July 1999 and June 2002 , and declared its willingness to do so to pay $ 160 million in compensation through 2009.

On December 2, 2004, four executives agreed to serve four to six months' imprisonment and to pay a fine of 250,000 US dollars each (the equivalent of around 188,000 euros): An Infineon spokesman stated that this conviction was a matter for those affected Manager and the company has taken measures to prevent further excesses of this kind.

On May 19, 2010, the EU Commission imposed a fine of 56.7 million euros on Infineon AG for illegal price fixing for DRAM chips with chip manufacturers Micron , Samsung , Hynix , NEC , Hitachi Zosen , Mitsubishi , Toshiba , Elpida and Nanya Technology .

Corruption scandal

In July 2005, the Munich public prosecutor's office investigated suspected bribery , breach of trust and tax evasion against Infineon's top managers. Were mentioned by name Andreas von Zitzewitz , formerly COO and CEO of memory chip division, Harald Eggers , a former Infineon manager of the Swiss technology company Unaxis initiated Holding AG, and Udo Schneider , owner of the Swiss sponsoring agency BF Consulting. As a result, Andreas von Zitzewitz resigned as a member of the board on July 18, 2005 with immediate effect.

Business ethics

All production sites have OHSAS 18001 certification for the occupational health and safety management system. According to Infineon, it practices a preventive approach with the aim of minimizing possible dangers. It's about avoiding accidents and preventing any work-related incident that could result in injury or illness.

In September 2010, Infineon was included in the Dow Jones Sustainability Index .
