SK Materials Co., Ltd. Company Introduction

SK Materials Co., Ltd. is a key affiliate company belonging to the SK Group in South Korea. It is a leading company specializing in the production and supply of specialty gases, industrial gases, and other advanced IT materials that are essential for manufacturing processes in the semiconductor, display panel, and solar cell industries.

Main Business: Manufacturing and sales of advanced materials for semiconductor and display production processes, including specialty gases (such as NF3, WF6, SiH4), precursors, etching gases, etc.

Establishment and History: Founded in 1982 (formerly OCI Materials), the company has accumulated significant technological expertise. It was acquired by SK Group in 2016 and renamed SK Materials. In December 2021, it was merged into SK Inc., the group's holding company, and now constitutes a significant part of SK Inc.'s Advanced Materials business division.

Production Facilities: Operates large-scale production plants (factories) in locations such as Yeongju, Gyeongsangbuk-do, manufacturing products based on its own proprietary technology.

Conclusion: Factory or Trading Company?

SK Materials is fundamentally a manufacturer (a factory-based company) that possesses its own production facilities (factories) and directly manufactures its products. It is not simply a trading company that distributes goods.

here are the main types of products produced or sold by South Korea's SK MATERIALS CO., LTD., translated into English:

SK Materials primarily focuses on producing and supplying advanced materials crucial for the semiconductor, display, and other high-tech industries. Their main product categories include:

1. Specialty Gases (특수가스): These are high-purity gases used in manufacturing processes like etching, deposition, and cleaning.

Nitrogen Trifluoride (NF₃): Used for chamber cleaning in semiconductor and display manufacturing.

Tungsten Hexafluoride (WF₆): Used for depositing tungsten layers in semiconductor manufacturing.

Silane (SiH₄): Used for depositing silicon-based films.

Disilane (Si₂H₆): Another silicon source gas.

Dichlorosilane (DCS - SiH₂Cl₂): Used in silicon epitaxy and deposition.

Other Etching Gases: Such as C₄F₆, CF₄, CHF₃, etc.

2. Precursors (전구체): These are chemical compounds used in Atomic Layer Deposition (ALD) and Chemical Vapor Deposition (CVD) to create thin films on wafers.

Silicon Precursors: For depositing silicon oxide (SiO₂) or silicon nitride (SiN) films (e.g., HCDS - Hexachlorodisilane).

High-k Precursors: For creating high dielectric constant layers in advanced transistors.

Metal Precursors: For depositing various metal layers.

(Note: Often supplied through subsidiaries or joint ventures like SK Trichem)

3. Silicon Carbide (SiC) Wafers (실리콘 카바이드 웨이퍼): Used as substrates for power semiconductors, which are increasingly important for electric vehicles and renewable energy applications.

(Note: This business area was significantly strengthened via the acquisition of the SiC wafer unit, previously part of DuPont, now often associated with SK Siltron, another SK affiliate, but SK Materials has also been involved in the SiC value chain).

4. Photoresists (포토레지스트) and related materials: Chemicals used in the photolithography process to pattern circuits onto wafers.

(Note: Often developed/supplied through joint ventures, such as the one previously with JNC - SK Materials JNC).

5. Industrial Gases (산업용 가스): Basic industrial gases like Nitrogen (N₂), Oxygen (O₂), and Argon (Ar), often supplied on-site to large industrial customers (like semiconductor fabs) through subsidiaries such as SK Materials Airplus.

In summary, SK Materials provides essential high-purity gases and chemical materials primarily serving the semiconductor and display manufacturing industries, with expanding interests in next-generation materials like SiC wafers and potentially battery materials components.
