Unlocking Growth in Semiconductors: Outsourced Semiconductor Assembly and Test (OSAT’s) Pivotal Role and Emerging Opportunities for Service Providers | Blog
The semiconductor industry, a cornerstone of the modern technological landscape, is experiencing rapid growth, fueled by advancements in AI, consumer electronics, automotive innovations, and the widespread adoption of connected devices.
Central to this expansion are Outsourced Semiconductor Assembly and Test (OSAT) services, which play a crucial role in bridging the gap between wafer fabrication and the production of functional integrated circuits.
Once semiconductor wafers are fabricated, they must undergo assembly, packaging, and extensive testing to meet strict performance and specification standards. This is where OSAT providers come in, offering specialized services that include die assembly, packaging solutions, and integrated circuit (IC) testing.
By managing these complex and critical processes, OSAT firms allow semiconductor companies, particularly fabless ones, to concentrate on design and innovation while ensuring their products meet the rigorous standards required by diverse end markets.

Key drivers shaping the OSAT market
Geopolitical fragmentation and regional investments: The OSAT industry is becoming more geographically fragmented, due to rising geopolitical tensions, leading to a diversification of manufacturing hubs away from traditional regions including Taiwan.
Emerging markets in the Asia-Pacific (APAC) region, including Malaysia, Vietnam, and India are becoming critical players, with substantial investments in advanced semiconductor packaging and testing. Malaysia controls around 13% of the global OSAT market and has attracted key players such as Intel and Infineon. Vietnam is also making significant strides, with Amkor recently opening a facility to provide advanced packaging solutions for sectors including automotive and high-performance computing. Furthermore India, is positioning itself as a growing player, with increasing investments in OSAT capabilities, including partnerships with companies including Foxconn. These shifts reflect the need for resilience in semiconductor supply chains, especially amidst US-China trade tensions and global chip shortages. For service providers, this diversification presents opportunities to establish stronger ties with semiconductor manufacturers looking to tap into these emerging markets.
Rising demand from the automotive and electronics Sectors: The increasing complexity of semiconductors required in automotive applications, such as electric vehicles (EVs), advanced driver-assistance systems (ADAS), and autonomous driving, has significantly boosted OSAT demand. The electronics sector, driven by innovations in smartphones, internet of things (IoT) devices, and 5G infrastructure, further fuels this demand. As the complexities of chip design and manufacturing increase, there is a growing need for sophisticated testing and packaging, a niche in which OSAT providers excel.
Industry insight
As semiconductor companies shift focus towards more advanced technologies, understanding the shifting landscape of OSAT presents both challenges and lucrative opportunities for service providers.
For engineering service providers, this opens the door to new partnerships and outsourcing contracts, particularly in engineering research & development (ER&D), supply chain optimization, and the deployment of advanced packaging solutions.
The convergence of semiconductor innovation with other technological domains, such as artificial intelligence (AI), also presents opportunities to create differentiated offerings that cater to specific verticals.
Opportunities for service providers
- Advanced packaging and testing solutions: The rise of advanced technologies, such as high-bandwidth memory (HBM) and system-on-chip (SoC) solutions, demands cutting-edge packaging and testing.
Service providers can develop advanced testing methodologies and employ tools such as digital twins for simulation. Incorporating AI into these processes can enhance predictive analytics and optimize testing protocols, significantly reducing time and costs.
- Process automation and efficiency enhancements: The need to enhance efficiencies and optimize costs has emerged as a key priority for OSAT companies. Service providers now have an opportunity to work with these firms to identify processes that can be automated and enhanced using digital technologies. Incorporating IoT solutions for instance, can provide real-time data analytics for monitoring production lines, allowing for proactive adjustments and maintenance.
- Talent development: One of the biggest challenges for the OSAT industry comes within building the talent pool needed to support rapid growth. Countries such as Vietnam are already investing in talent development, with a goal in place to train 50,000 semiconductor engineers by 2030. Service providers can support these initiatives, by offering tailored training programs or collaborating with universities and local governments, to create specialized workforce development programs and offering the requisite talent to OSAT firms.
- Infrastructure investments: Infrastructure investments, particularly in labs and ER&D centers, are also becoming crucial to meet OSAT needs, presenting another opportunity for service providers to offer high-value support. Service providers can assist OSAT companies by developing state-of-the-art facilities that enhance research capabilities and support advanced manufacturing processes.
Conclusion: A strategic entry point for service providers
The OSAT market, currently valued at $40-45 billion, is poised for significant growth, driven by increasing demand for advanced semiconductor technologies.
Service providers that align their capabilities with semiconductor clients’ needs—through advanced packaging, talent management, or ER&D—can capitalize on this expanding market by positioning themselves as strategic partners in the global semiconductor value chain.
Service providers targeting this opportunity will need to segment the market, identify key opportunities, and develop focused attack strategies based on actionable market intelligence, which is something our expert team can provide in the form of insights, needed to effectively navigate this ever-changing landscape.
