Silicon Integrated Systems (SIG), headquartered in Taiwan, is a major provider of semiconductor back-end services, specializing in testing and packaging of semiconductor devices. The company reported revenue of NT$1.976 billion (NT$1,976,452 thousand) for May 2026, a significant 23.7% increase compared to NT$1.597 billion in the same month of the previous year. This growth is attributed to rising demand for AI-related chips and high-performance computing (HPC), expanded investments in advanced packaging technologies, and stable order inflows from global customers.

In recent years, SIG has strengthened strategic partnerships with foundries and integrated device manufacturers (IDMs), expanding production capacity to meet growing demand in 5G, autonomous driving, and IoT applications. The company has also enhanced its offerings in advanced packaging technologies such as System-in-Package (SiP) and Fan-Out packaging, which support miniaturization and higher integration—key trends in the semiconductor market. These advancements have contributed to higher average selling prices and improved profitability.

Since the beginning of 2026, SIG’s monthly revenue has consistently shown year-over-year growth, reflecting not only a recovery in overall industry demand but also the success of the company’s technology differentiation strategy. Looking ahead, demand for testing services related to AI accelerators and next-generation communication infrastructure is expected to grow, raising the possibility of an upward revision to the company’s full-year 2026 financial outlook.

Key areas to watch include progress in capital expenditures, new customer acquisition, foreign exchange fluctuations, and market share competition with rivals such as King Yuan Electronics and Advantest (Taiwan). Amid ongoing U.S.-China tech tensions, global customers are increasingly diversifying their supply chains, and SIG’s position as a Taiwan-based player is becoming a strategic advantage in securing new business.
