由於《晶片技術創新法案》(CHIPS Act)的資助,北美重新獲得了其戰略重要性。安姆科(Amcor)在亞利桑那州破土動工興建先進封裝工廠,為美國國內的汽車和人工智慧客戶提供產品。德克薩斯)投資600億美元建造了多個晶圓廠和後端設施,而天水(Skywater)以9300萬美元收購了英飛凌(Infineon)位於奧斯汀的晶圓廠,從而實現了全國範圍內的產能冗餘。
歐洲已從利基研發轉向大規模生產。 Silicon Box 已獲得歐盟核准,將在義大利建造一座價值 13 億歐元(14.7 億美元)的面板級晶圓廠,目標是每年生產超過 1 億個 SiP 單元。泰雷茲、Radial 和富士康正在探索建立一個面向國防和航太用戶的法國 OSAT 聯盟。安森美半導體已在捷克共和國投資 20 億美元建造一條碳化矽生產線,以確保電動車計劃的本地供應。中東和非洲地區作為新興市場持續成長,以色列和阿拉伯聯合大公國正在探索相關政策框架以吸引下游投資者。
The outsourced semiconductor assembly and test market was valued at USD 47.09 billion in 2025 and estimated to grow from USD 51.12 billion in 2026 to reach USD 77.12 billion by 2031, at a CAGR of 8.56% during the forecast period (2026-2031).

Sustained progress in artificial intelligence, high-performance computing, and automotive electrification raised demand for advanced packages and safety-critical test flows, thereby widening the total addressable opportunity for specialized backend service providers. Asia-Pacific suppliers preserved pricing leverage owing to mature ecosystems, yet policy-driven capacity build-outs in North America and Europe began to reshape global supply allocation. Hybrid chiplet architectures elevated the importance of heterogeneous integration, motivating strategic investments in fan-out wafer-level and 2.5D/3D platforms. Meanwhile, tighter trade controls and sustainability mandates encouraged customers to shift part of the workload to geographically diversified sites that can demonstrate lower energy use per unit throughput. As foundry capacity remained strained, fab-lite semiconductor companies continued to outsource backend steps, reinforcing the structural relevance of the outsourced semiconductor assembly and test market in the next planning cycle.
Automotive OEMs transitioned toward software-defined platforms, lifting semiconductor bill-of-materials per car and intensifying demand for high-reliability packages. Volkswagen Group's traction inverter partnership with onsemi highlighted the rising adoption of silicon carbide devices that need thermally robust power packages.Imec's Automotive Chiplet Program, supported by ASE, BMW, and Bosch, illustrated cross-value-chain alignment on standardized chiplet packaging for functional safety compliance. OSAT providers that qualify to AEC-Q100 and ISO 26262, therefore, captured new design wins and secured multiyear capacity reservations with electric-vehicle suppliers.
Commercial 5G base-station roll-outs moved the radio front-end into millimetre-wave territory, necessitating low-loss substrates, conformal shielding, and compact SiP footprints. Finwave Semiconductor's E-mode MISHEMT integration at GlobalFoundries signalled commercial deployment of novel gallium-nitride devices that require specialised RF packaging, with mass qualification targeted for 2026. The pipeline for 6G testbeds already incorporates co-packaged optics, urging OSAT firms to expand mixed-signal assembly capabilities and advanced thermal solutions.
TSMC's Wafer Manufacturing 2.0 strategy integrated packaging and testing flows, offering turnkey services that reduced addressable volume for stand-alone OSAT companies. Samsung pursued a similar path, while Intel grew its foundry services to include advanced interposers. These moves compressed third-party share in high-margin segments and obliged OSAT firms to double down on niches such as automotive safety or photonics.

Testing captured a 10.35% CAGR forecast for 2026-2031, a pace outstripping packaging's expansion yet starting from a smaller base. AI and high-performance computing designs demanded system-level test coverage that verifies chiplet interconnect latency, dynamic thermal throttling, and deep-learning workload performance under varied voltages. The outsourced semiconductor assembly and test market responded by integrating adaptive machine-learning algorithms in automatic test equipment, cutting test time while improving fault isolation.
Packaging retained 76.80% of 2025 revenue, but its composition evolved toward fan-out panel-level, 2.5D interposer, and co-packaged optics lines. As customers consolidated suppliers, OSAT groups bundled turnkey offerings that merge fixture design, final test, and logistics. Advantest secured its sixth consecutive leadership in assembly test equipment after adding AI-enabled analytics to its V93000 series.
Ball grid array technology maintained a 23.85% share in 2025 by serving mainstream consumer and industrial platforms that value mechanical robustness. However, fan-out wafer-level packages expanded at 11.02% CAGR as mobile processors and AI accelerators transitioned to high-density redistribution layers. This trend strengthened the outsourced semiconductor assembly and test market because only a limited pool of vendors can process larger panel formats without yield drift.
ASE's USD 200 million panel-level expansion to 310 mm X 310 mm glass panels illustrated a cap-ex commitment toward cost-effective, large-area builds. Through-silicon-via and through-glass-via variants proliferated in high-bandwidth memory stacks. FC-BGA substrates benefited from advanced node adoption, bridging the gap between organic laminates and silicon interposers for networking ASICs.
