Infineon Technologies

Infineon Technologies AG was founded on April 1, 1999 when the semiconductor operations of parent company, Siemens AG, were spun off to form a separate legal entity. As of September 30, 2010 Infineon has 26,650 employees worldwide. In the 2010 financial year, the company achieved sales of €3.295 billion.

On May 1, 2006, Infineon's Memory Products division was carved out as a distinct company called Qimonda AG, which, at its height, employed about 13,500 people worldwide. Qimonda was listed on the New York Stock Exchange until 2009.[2]

The markets of Infineon Technologies

Infineon Technologies AG, Neubiberg near Munich offers semiconductor and system solutions for automotive, industrial and multimarket sectors, for mobile communication, as well as chipcard and security products. With a global presence, Infineon operates through its subsidiaries in the USA from Milpitas in the Asia-Pacific region from Singapore and in Japan from Tokyo.

Infineon has a number of facilities in Europe. Infineon's high power segment is in Warstein (Germany), Villach (Austria) and Cegléd (Hungary) and Italy. It also runs R&D centres in France, Singapore, Romania, Taiwan & Bengaluru & fabrication units in Singapore, Malaysia, Indonesia & China.

Infineon is listed in the DAX index of the Frankfurt Stock Exchange.

In 2010, a proxy contest broke out in advance of the impending shareholders' meeting over whether board member Klaus Wucherer would be allowed to step into the chairman's office upon the retirement of the then-current chairman, Max Dietrich Kley.

Infineon also has an HPS (High Power Segment). The front-end of this production is in Warstein (GER), the back-end is in Cegléd (Hungary). Thyristors, diodes and IGBTs are manufactured here.

In August 2010, Intel agreed to buy the wireless operations of Infineon for about $1.4 billion[3]


During the 2008 Olympic Games in Beijng in August, Chinese automobile manufacturer Chang'an Motors supplied a number of hybrid-drive cars as taxis for the athletes and spectators. The power electronics for the "mild hybrid" drive (HybridPACK 1) was supplied by Infineon.[4][5]

Acquisitions and divestitures

Infineon announced the buy-out of the cellular division of LSI in August 2007.[6] This division belonged to the erstwhile Agere Systems before it merged with LSI. In 2010, this unit would ultimately be divested to Intel.
In August 2007 it completed the acquisition of TI's DSL CPE business group. This group has been merged with the communications product group at Infineon.


International Rectifier
Fairchild Semiconductor
Dynex Semiconductor


Major institutional investors in Infineon are: Dodge and Cox International: 10.03%, Merrill Lynch International: 5.25%, Templeton Global Advisors Limited: 5.16%, Capital Group International: 4.14%.[7]

Price fixing controversy

In 2004–2005 an investigation was carried out into a worldwide DRAM price fixing conspiracy during 1999–2002 that damaged competition and raised PC prices. As a result, Samsung is to pay $300 million fine, Hynix was to pay $185 million in 2005, Infineon: $160 million in 2004. Micron Technology cooperated with prosecutors and no fine is expected.


AENEON was introduced in 2005. AENEON is a DRAM memory family of Infineon and fits into standard PCs and notebooks.

AENEON targets whitebox (non-brand) PC and notebook manufacturers world wide, as well as the European retail segment and end users (web shop). AENEON DRAM memory focuses the "price-performance" segment.

Price advantages are obtained due to a limited product portfolio (only unbuffered and SO-DIMM), and due to outsourced module assembly. The DRAM components, however, are "Made by Infineon".
