Infineon Technologies AG (IFX) designs, develops, manufactures, and markets semiconductors and complete systems solutions used in a variety of microelectronic applications, including computer systems, telecommunications systems, consumer goods, automotive products, industrial automation, control systems, and chip card applications. The company's products include: standard commodity components, full- and semi-custom devices and application-specific components for memory, analog, digital, and mixed-signal applications. Infineon operates in Europe (approximately 32% of its revenues for full year 2007 with Germany contributing 15% of the total revenues), North America (25%), Asia (42%, with Japan contributing 9% of total revenues) and the rest of the world (1%). The company has organized its business into three segments: Communications, Automotive & Industrial, and Qimonda (formerly its Memory Products division), with any remaining activities being filed under Other and Corporate Activities.
The Communications group (approximately 13.7% of revenues, for the full year 2007 or 25.8% of revenues from the stand-alone Infineon) comprises its Wire-line Communications and Secure Mobile Solutions (SMS) business groups. This group produces semiconductors, memory controllers, fiber-optics and optical networking components, along with any other semiconductors and complete system solutions across various sectors of the communications market.
The Automotive, Industrial, and Multimarket (AIM) group (39.3% of total revenues, or 74.1% of stand-alone revenues) is comprised of its Automotive and Industrial group, the ASIC & Design Solutions unit, and the Chipcard and Security Integrated Circuit (IC) unit.
Qimonda (46.9% of total revenues), formerly the Memory Products Division, produces semiconductor memory products for use in standard, specialty, and embedded memory applications. These products include: mainstream Dynamic Random Access Memory (DRAMs, 128-Mbit and 256-Mbit), high-end DRAMs (512-Mbit), high-performance and low-power specialty DRAMs, as well as embedded DRAM products. This group filed for an IPO with the US SEC, and Infineon sold approximately 20% of the division, and it continues to integrate Qimonda's operations into its financial statements until it decides what to do with its additional 80% stake. In September 2007, Infineon sold 25 million Qimonda American Depositary Receipts at $10.92 each, reducing its stake to 78.6 percent and raised about $272 million. Infineon's ownership in Qimonda stands at 77.5% after it sold 28.75 million shares in the fourth quarter of 2007. In August 2007 Infineon said that it planned to lower its stake in Qimonda to less than 50 percent within two years.
