Nepes Ark Corp. is a South Korea-based outsourced semiconductor assembly and test (OSAT) service provider specializing in comprehensive back-end testing solutions for system semiconductors and advanced microelectronics. Founded in 2019 as a spin-off from Nepes Corporation and headquartered in Cheongju-si, Chungcheongbuk-do, South Korea, the company operates high-volume testing facilities serving global integrated device manufacturers (IDMs) and fabless semiconductor companies. Nepes Ark Corp. offers an extensive portfolio of semiconductor testing and post-fab engineering services, comprising: wafer probe testing and electrical die sorting (EDS) to assess circuit performance and parametric yield at the wafer stage; package final testing across wide temperature, voltage, and frequency ranges to guarantee functional reliability; back-end processing services, including wafer thinning and back-grinding, precision dicing, automated optical inspection, laser marking, and tape-and-reel packaging; dedicated testing services for power management integrated circuits (PMIC); application processor (AP) and system-on-chip (SoC) testing; display driver integrated circuit (DDI) testing; complementary metal-oxide-semiconductor (CMOS) image sensor (CIS) testing; radio frequency (RF) integrated circuit testing; touch controller IC testing; and wafer-level testing compatible with advanced packaging architectures, including Fan-Out Wafer-Level Packaging (FOWLP) and Fan-Out Panel-Level Packaging (FOPLP). In recent strategic developments, Nepes Ark Corp. has expanded its testing infrastructure and automated test equipment (ATE) capacity to support high-performance on-device artificial intelligence (AI) processors and neural processing units (NPUs). The company has also broadened its operational footprint in the automotive semiconductor segment by expanding certified testing lines for automotive-grade PMICs and sensor ICs. Additionally, Nepes Ark Corp. has strengthened operational synergies within the Nepes Group ecosystem, partnering with parent company Nepes Corporation and advanced packaging affiliates to deliver integrated, turnkey packaging and testing solutions while diversifying its customer portfolio across international fabless chip design firms.
