ISC Co., Ltd., a global leader in semiconductor test components, has released its semi-annual report for the period ending June 30, 2026. The company specializes in the development and manufacture of semiconductor test sockets, specifically maintaining a dominant 90% global market share in the elastomer (silicone rubber) socket market. The company has strategically expanded its portfolio to include AI semiconductor test sockets for global big tech and fabless customers, as well as Pogo pin and Burn-in test sockets.
For the reporting period, ISC recorded consolidated revenue of 141,201 million KRW (~$99.7M USD based on 1416 KRW/USD). The revenue stream is primarily driven by the manufacture of test sockets (iSC, etc.), which accounted for 83.7% of total sales, followed by test components at 15.4%.
To strengthen its position in the AI and High Bandwidth Memory (HBM) markets, ISC acquired iSemi and TechDream in the second quarter of 2025. This strategic move allows the company to provide a comprehensive test platform, including module testers for DRAM, high-speed burn-in testers, and specialized cleaning chemicals used in the etching processes of DRAM and High Bandwidth Memory (HBM).
