ISC Co., Ltd., now part of SK Group, to expand semiconductor plant in Songdo; operations to begin in 2028

【Financial News | Incheon — Reporter Han Gab-soo】 ISC Co., Ltd. (ISC), a company specializing in semiconductor test sockets, will add a new plant in Songdo, Incheon, combining production and research and development. The investment aims to strengthen manufacturing capabilities in response to the expanding artificial intelligence (AI) semiconductor market and broaden the company’s global business base.
The Incheon Free Economic Zone Authority said on the 12th that a groundbreaking ceremony for ISC’s new plant was held at the Songdo Knowledge Information Industry Complex.
The new plant will house research facilities for next-generation AI semiconductors and advanced manufacturing equipment for producing semiconductor test sockets. The goal is to complete construction by 2027 and begin full-scale operations in 2028.
ISC Co., Ltd. produces test sockets that connect semiconductor chips to inspection equipment so the chips’ electrical characteristics can be checked. It supplies key components for the back-end processes used to verify semiconductor performance and quality. It became an SK Group affiliate after being acquired by SKC in 2023.
A key feature of this investment is that it will bring research and development functions together at one site, going beyond a simple expansion of production facilities. The company plans to strengthen its technological competitiveness in AI semiconductors and diversify its customer base, using the new Songdo plant as a foundation. In particular, it plans to increase the share of AI-related sales and broaden its business in global markets.
The Incheon Free Economic Zone Authority expects the investment to have a positive impact on the region’s semiconductor industry ecosystem as well. It believes that strengthening the competitiveness of companies in semiconductor manufacturing as well as in back-end processes such as inspection and evaluation, could also help expand the advanced-industry base centered on Songdo.
Kim Jeong-ryeol, CEO of ISC Co., Ltd., said, “We will use construction of the new plant as a springboard to raise our research and development capabilities to a global level and expand our entry into overseas markets.”
Incheon Free Economic Zone Authority Commissioner Kim Jong-cheol said, “We will support companies so they can invest and grow steadily.”
