Greater competitiveness in manufacturing, technology, quality,
and sustainable growth are the strengths that SK siltron is seeking in its
journey to become a global top player in the semiconductor wafer market.

The only semiconductor wafer manufacturer in Korea, SK siltron has spent the last 40 years growing and contributing to the development of the global semiconductor industry.

SK siltron has garnered recognition for manufacturing, technology, and quality by drawing on extensive experience and through constant R&D. The designation of our 300 mm ingot growing technology as a “national core technology” by the Korean government has further affirmed our growing competitiveness to date. Today, the development and supply of wafers for next-generation semiconductors that are customized to individual customers is our core business area.

Furthermore, to proactively respond to the growing semiconductor market we are expanding our production of Si wafers. We are also expanding our business portfolio to include new items such as SiC wafers which we believe will be a strong new growth initiative.
We have our sights set on the continuous innovation of our entire wafer manufacturing process, including growing, shaping, polishing, and cleaning to maximize our capacity for manufacturing, technology, and quality. Through strategic collaborations in relation to products, materials, and equipment, we aim to enhance our growth potential.

As part of our commitment to becoming the lowest-carbon wafer supplier, we are improving our process efficiency and increasing our renewable energy usage to achieve the Net Zero 2040 target set by the SK Group. Based on SK's philosophy of "Happy Management," we will strive to create a sustainable future by pursuing the happiness of our customers, partners,
and local communities.

We ask for your support as SK siltron grows into a global top player. We would love to have you join us, every step of the way.
