- ALT Co., Ltd. is a South Korea-based outsourced semiconductor assembly and test (OSAT) service provider specializing in post-fabrication semiconductor testing and advanced backend packaging solutions. Founded in 2003 and headquartered in Cheongju-si, Chungcheongbuk-do, South Korea, the company operates manufacturing and testing cleanroom facilities within the Ochang Science Industrial Complex. ALT Co., Ltd. provides turnkey wafer testing, final package testing, test program development, and specialized wafer-level backend processing. The company's core product and service portfolio comprises CMOS Image Sensor (CIS) testing and post-processing; Display Driver Integrated Circuit (DDI) testing for mobile, IT, and television display applications; Power Management Integrated Circuit (PMIC) testing; high-voltage power discrete and power module testing, including Insulated Gate Bipolar Transistors (IGBT), Silicon Carbide (SiC), and Gallium Nitride (GaN) devices; Microcontroller Unit (MCU) and System-on-Chip (SoC) functional testing; and proprietary backend handling services, such as Rim-Cut wafer edge trimming, backgrinding, laser sawing, recon packaging, and tape-and-reel finishing for ultra-thin wafers. The company serves domestic and international integrated device manufacturers (IDMs) and fabless semiconductor companies across the automotive, mobile communications, consumer electronics, and industrial markets. In recent operational developments, ALT Co., Ltd. completed its initial public offering on the KOSDAQ exchange in July 2023 (KRX: 459550). The company has expanded its manufacturing footprint through capacity additions and automated test equipment investments at its Ochang production complex, strategically scaled its testing capabilities for high-growth electric vehicle (EV) automotive power semiconductors and next-generation high-resolution CIS devices, and broadened partnerships with domestic semiconductor manufacturers for advanced thin-wafer reconstruction and edge-trimming processing.
