ISC Co., Ltd. (KOSDAQ: 095340) is headquartered in Seongnam, South Korea and operates in the semiconductor technology ecosystem, with a focus on components that support semiconductor testing. The company’s core business is the global design, manufacture, and distribution of “test critical” hardware used to evaluate semiconductor devices during production and validation. Its product range covers multiple layers of the semiconductor testing stack—from device interfacing and physical connection to the fixtures and interconnect elements required to run automated and high-throughput test flows.
From a product and service perspective, ISC supplies semiconductor test sockets (including memory test sockets), burn-in apparatus, interposers, testing fixtures, probe heads, and other related components such as connectors and board protectors. These offerings typically matter because semiconductor test systems require high reliability, stable electrical performance, mechanical precision, and compatibility with device/package types and test architectures. ISC positions itself as a provider of “total test solutions,” indicating that customers can source coordinated components that fit into their broader test equipment and manufacturing processes.
Regarding corporate scale and operations, the company employs a little over two hundred people (reported around 206 employees in the provided dataset). For financial and capital structure context, the latest dataset also shows strong operating profitability indicators (e.g., margins on an LTM/TTM basis) and meaningful liquidity ratios, suggesting the company is actively funding working capital needs and ongoing operations.
The company also has a subsidiary-related operating line outside pure semiconductor testing: the description notes restaurant operations through subsidiaries. While this appears secondary to the semiconductor test component business, it indicates diversification of revenue streams.
Key management includes Jeong-Ryeol Kim as CEO. Founded in 2001, ISC has built specialization in semiconductor test hardware over multiple years, serving international customers and participating in an industry where test time, yield, and equipment reliability directly influence customer economics. From an investor’s viewpoint, the company’s valuation metrics and profitability profile (as provided) can be viewed in relation to the demand cycle for semiconductor testing equipment/components, where customer capex and product mix can drive revenue and margin outcomes.
Overall, ISC’s strategy centers on supplying mission-critical semiconductor test interfaces and components—products that are essential to manufacturing throughput and device validation—while maintaining organizational capabilities to support production, quality control, and distribution at scale.
