Infineon Brand Company Profile and Display Business Introduction

I. Company Profile
1. General Overview
Infineon Technologies AG is one of the world’s leading semiconductor manufacturers, headquartered in Neubiberg, near Munich, Germany. The company originated from the semiconductor division of Siemens AG, was spun off independently in 1999, and was publicly listed in 2000. After more than two decades of development, Infineon has become a core global supplier in power semiconductors, automotive semiconductors, embedded security, sensors, and wireless connectivity.
Infineon’s products and technologies are widely used in electric vehicles, renewable energy, industrial automation, data center power supplies, IoT terminals, smart homes, payment security, identity authentication, medical devices, rail transit, and other critical fields. Its core value can be summarized as follows: making energy more efficient, mobility safer, connectivity more reliable, and systems more intelligent.
Unlike consumer electronics or display panel brands, Infineon does not focus on “screen displays” as its main business. Instead, its core offerings are semiconductor chips, power modules, microcontrollers, sensors, and security devices. Therefore, Infineon’s “display business” is better understood as technology showcasing, application demonstrations, reference design displays, development platform presentations, industry solution exhibitions, and digital brand communication.

2. Development History
Infineon’s development history is closely tied to the evolution of the global power electronics, automotive electronics, and semiconductor industries.
The company originally came from the semiconductor business of Germany’s Siemens Group. During the second half of the 20th century, Siemens accumulated deep technical expertise in power devices, microcontrollers, and communication chips. As global semiconductor competition intensified, Siemens decided to operate its semiconductor division independently, leading to the creation of Infineon.
After becoming independent, Infineon went through cycles of volatility in the global semiconductor industry. However, by continuously focusing on high-barrier and high-growth fields, it gradually established a leading position in power semiconductors and automotive electronics.
Key milestones include:
1999: Spun off from Siemens and established as Infineon Technologies.
2000: Listed on the Frankfurt and New York stock exchanges.
2000s–2010s: Continuously strengthened its businesses in IGBTs, MOSFETs, microcontrollers, RF chips, and security chips.
2015: Acquired U.S.-based International Rectifier, greatly enhancing its capabilities in power semiconductors, gate drivers, and industrial power solutions.
2020: Completed the acquisition of Cypress Semiconductor, gaining key assets in automotive memory, microcontrollers, PSoC, wireless connectivity, and industrial interfaces.
Recent years: Continued expansion around silicon carbide, gallium nitride, automotive electronics, IoT security, edge AI, and green energy.
Through these strategic moves, Infineon has evolved from a traditional power device manufacturer into a comprehensive semiconductor platform company covering sensing, computing, control, connectivity, security, and power conversion.

3. Core Advantages
1) Global Leadership in Power Semiconductors
Infineon is a major global leader in power semiconductors. Its products include IGBTs, MOSFETs, silicon carbide Schottky diodes, SiC MOSFETs, GaN devices, power modules, gate drivers, and power management chips. These power devices are widely used in PV inverters, energy storage systems, motor drives, charging stations, server power supplies, industrial power systems, and electric vehicle powertrain control systems.
2) Core Supplier of Automotive Semiconductors
Infineon has strong influence in automotive electronics, providing chips and system solutions for powertrain, chassis safety, body electronics, EV electrification systems, autonomous driving, in-vehicle networking, and security systems. Its AURIX microcontroller family is known for functional safety and is widely used in engine control, electric power steering, braking systems, battery management, and domain controllers.
3) Leading Wide-Bandgap Semiconductor Technology
Driven by the trends of new energy and high-efficiency power conversion, Infineon has heavily invested in silicon carbide and gallium nitride. Compared with traditional silicon-based devices, SiC and GaN can operate at higher voltages, higher frequencies, and higher temperatures, significantly reducing switching losses and system size. Infineon’s CoolSiC and CoolGaN technologies have become important foundations for electric vehicles, fast charging, data center power supplies, and PV energy storage systems.

4 Complete Security and Connectivity Capabilities
Through acquisitions such as Cypress, Infineon has strengthened its capabilities in wireless connectivity, memory, microcontrollers, and security chips. Its OPTIGA security devices, TPM trusted platform modules, Wi-Fi/Bluetooth combo chips, PSoC platforms, and automotive Ethernet products enable the company to cover secure connectivity needs from edge devices to the cloud.
5) System-Level Solution Capability
Infineon does not merely supply individual chips. It provides customers with complete system solutions, including reference designs, evaluation boards, simulation models, driver software, protocol stacks, secure firmware, and application notes. This “chip + software + system” capability gives Infineon a clear advantage in complex industrial and automotive projects.
