Company Introduction: SK SILTRON CSS KOREA CO., LTD.

Business Type: Manufacturer (Factory)

English Introduction:

SK SILTRON CSS KOREA CO., LTD. is a South Korean company specializing in advanced semiconductor materials. It operates as a subsidiary of SK Siltron, a major global wafer manufacturer and part of the South Korean conglomerate SK Group.

The company was effectively established following SK Siltron's acquisition of DuPont's Silicon Carbide (SiC) wafer business unit in early 2020. This strategic acquisition positioned SK Siltron (and subsequently SK Siltron CSS) as a key player in the rapidly growing market for SiC wafers.

Core Business:

SK SILTRON CSS focuses on the manufacturing and supply of Silicon Carbide (SiC) wafers. SiC wafers are a critical substrate material for next-generation power semiconductors. These semiconductors offer significant advantages in terms of efficiency, heat resistance, and power density compared to traditional silicon-based chips.

Key Applications:

The SiC wafers produced by SK Siltron CSS are essential components for high-growth industries, including:

Electric Vehicles (EVs): Used in inverters, onboard chargers, and DC-DC converters for improved range and faster charging.

Renewable Energy: Employed in solar inverters and wind turbine converters for higher energy conversion efficiency.

5G Communications: Utilized in power supplies for base stations and data centers.

Industrial Power Supplies: For more efficient and compact power solutions.

Conclusion:

SK SILTRON CSS KOREA CO., LTD. is fundamentally a manufacturer (factory). It operates production facilities to produce SiC wafers. While it engages in the sale (trade) of its manufactured products, its primary identity and function are rooted in manufacturing advanced semiconductor materials.

here are the main products produced or sold by SK Siltron CSS, translated into English.

SK Siltron CSS specializes in compound semiconductor wafers, primarily Silicon Carbide (SiC), which are crucial for next-generation power electronics used in electric vehicles (EVs), renewable energy systems, and other high-efficiency power applications.

Products Manufactured or Sold by SK Siltron CSS:

Silicon Carbide (SiC) Wafers: This is their core product category.

Conductive SiC Substrates (N-type): Base wafers used for manufacturing power semiconductor devices like MOSFETs and diodes.

Semi-Insulating (SI) SiC Substrates: Used primarily for high-frequency RF devices (though less of a focus for CSS compared to conductive).

SiC Epitaxial Wafers (SiC Epiwafers): These are SiC substrates with an additional, precisely grown layer (epitaxial layer) of SiC on top. This layer has specific electrical properties required for device fabrication, offering a value-added solution to chipmakers.

Wafer Diameters: They primarily produce and are scaling up production for:

150mm (6-inch) SiC Wafers: Currently the industry standard and a major product line.

200mm (8-inch) SiC Wafers: Under active development and production scaling, representing the next generation for increased efficiency and cost reduction in chip manufacturing.

In summary, SK Siltron CSS is a key global supplier of Silicon Carbide (SiC) substrate wafers and SiC epitaxial wafers, focusing on the 150mm and rapidly expanding 200mm diameter market for power semiconductor applications.
