Siltronic AG is a Germany‐based manufacturer specializing in the production of hyperpure silicon wafers for the semiconductor industry. These wafers serve as the foundational substrate for a wide array of electronic devices, including integrated circuits, discrete power components and sensor technologies. Headquartered in Munich, Siltronic’s wafers are a critical input used by chipmakers worldwide to fabricate advanced microelectronic components for consumer electronics, automotive systems and industrial applications.
The origins of Siltronic trace back to its establishment as a spin-off from Siemens’ semiconductor materials division in 2001. The company built on decades of silicon‐crystal growth and wafer‐processing expertise, later becoming an independent publicly listed entity. Over the years, Siltronic has continued to invest in research and development—refining crystal‐pulling, wafer slicing and surface‐treatment technologies to meet escalating demands for larger diameters and tighter process tolerances.
Siltronic’s product portfolio encompasses prime-grade silicon wafers in diameters ranging from 100 mm to 300 mm, with specialized offerings such as epitaxial wafers, polished single‐side and double‐side polished substrates, as well as fully processed wafers for immediate use in chip fabrication. These products adhere to stringent specifications for purity, flatness, and defect density, supporting advanced nodes and enabling higher transistor densities, improved yields and enhanced device performance.
With manufacturing facilities located in Germany, the United States, Singapore and Taiwan, Siltronic operates a global supply chain that ensures timely delivery and localized support for major semiconductor hubs. The company’s customer base spans leading memory and logic foundries, power device producers and emerging markets in artificial intelligence and automotive electronics. Through continuous process optimization and capacity expansions, Siltronic aims to address the semiconductor industry’s evolving requirements for wafer quality, volume and reliability.
