Products and Services

Siltronic AG's portfolio is distinguished by its focus on high-quality silicon wafer products, tailored to meet the evolving needs of the semiconductor industry:

• Polished and Epitaxial Wafers: These wafers represent the core offerings from Siltronic AG, designed with precision for use in sophisticated semiconductor applications. Polished wafers undergo a fine surface finish process, making them ideal for high-end semiconductor manufacturing. Epitaxial wafers have an additional monocrystalline silicon layer grown on the polished wafer, which plays a crucial role in advanced microelectronics, including integrated circuits.
• Ultimate Silicon: This product is promoted as the optimal crystal for polished wafers, showcasing significant advancements in material purity and structural perfection. Ultimate Silicon caters to the highest standards of semiconductor manufacturing, where the quality of the base silicon crystal directly impacts the performance and reliability of the final electronic device.
• PowerFZ: PowerFZ stands out as a specialized wafer product developed through the float zone (FZ) method. This technique is renowned for producing silicon with exceptionally high purity and fewer defects, ideal for manufacturing power electronics, high-performance computing, and space applications. The float zone method involves melting a small region of a silicon rod and slowly moving this molten section along to refine the entire rod.
• HIREF: The HIREF product line introduces a high reflective non-polished wafer, intended for specific applications that benefit from its unique surface properties. These wafers are used in areas such as photonic devices, where the reflection characteristics of the wafer surface play a crucial role in the device's efficiency and performance.
