US Advanced Semiconductor Packaging Market is anticipated to expand at a high CAGR over the forecast period.
Advanced semiconductor packaging underpins the integration of multiple chips into compact, high-efficiency modules, critical for sustaining Moore's Law amid transistor scaling constraints. In the U.S., this market has emerged as a linchpin for national security and economic resilience, particularly as geopolitical tensions expose dependencies on overseas assembly. The sector encompasses techniques like flip chip and fan-out wafer-level packaging, which enable heterogeneous integration for AI accelerators and 5G infrastructure.

The federal incentives under the CHIPS and Science Act propel demand by subsidizing facility expansions tailored to advanced packaging. Hence, this funding mechanism lowers capital barriers for U.S.-based operations, compelling companies to localize production and thereby amplify orders for packaging services. For instance, under CHIPS Act’s National Advanced Packaging Manufacturing Program aims to allocate resources to develop domestic capabilities, directly stimulating procurement of flip chip and embedded die technologies as firms ramp up volumes to meet AI-driven quotas.
The growing AI infrastructure buildout acts as a primary catalyst, intensifying the need for heterogeneous integration that advanced packaging uniquely provides. As data center operators deploy high-bandwidth memory stacks, demand surges for 2.5D/3D solutions to manage power density and signal integrity. SEMI reports project 69% capacity growth in sub-7nm processes through 2028, largely attributable to AI workloads, which necessitate packaging innovations to interconnect logic and memory dies efficiently. This shift elevates U.S. market pull, as domestic hyperscalers prioritize resilient sourcing to avoid latency risks.
The geopolitical disruptions constrain demand by inflating raw material costs, followed by the recent reciprocal tariffs imposed by the US government will cause a delay in shipments, particularly for polymers essential to packaging integrity. This volatility dampens foundry investments, as end-users hesitate on expansions amid uncertain lead times, directly curbing packaging service uptake. Mechanical stresses in multi-die stacks exacerbate this, with NIST identifying thermal expansion mismatches as a persistent hurdle, leading to yield losses that deter high-volume commitments and suppress near-term demand.
Limited domestic expertise in soft materials presents another headwind, as U.S. capacity for advanced dielectrics and underfills trails Asian leaders. The Commerce Department's supply chain assessment reveals minimal assembly infrastructure, forcing reliance on imports that expose the ecosystem to tariffs and embargoes. Such dependencies erode confidence, prompting deferred orders for fan-out packaging and stalling growth in automotive applications where reliability is paramount.
Opportunities arise from standardization efforts, which streamline co-design and unlock scalable production for diverse applications. PMC analyses emphasize multi-scale modeling tools that reduce integration errors, enabling faster qualification and broader adoption across telecom and consumer electronics. By harmonizing interfaces, these advancements lower entry barriers, spurring demand as foundries integrate packaging earlier in workflows, potentially doubling throughput for 3D stacks
The U.S. advanced semiconductor packaging supply chain hinges on a hybrid global-domestic model, with assembly historically offshored to Asia-Pacific hubs like Taiwan and South Korea, where over majority of capacity resides. Key production centers include TSMC's facilities for front-end integration and Amkor's test sites, feeding into U.S. endpoints in New Mexico and Arizona. Logistical complexities arise from just-in-time wafer shipping, vulnerable to port delays and tariff impositions, further acting as a chokepoint.

Flip chip technology commands demand through its superior electrical and thermal performance, essential for high-density interconnects in AI and telecom applications. As transistor densities plateau, this method provides bonding dies directly to substrates via solder bumps, which facilitates shorter signal paths, thereby reducing latency in a much quicker manner as compared to wire bonding. Market pull intensifies from automotive electrification, where flip chip handles power IC stresses in EVs, ensuring reliability under high temperature excursions.
Foundries anchor demand for advanced packaging by outsourcing back-end processes to achieve cost-efficient scaling, particularly as U.S. fabs prioritize front-end logic. CHIPS incentives compel foundry players to procure U.S.-sourced packaging for compliance, directly hiking volumes for OSATs like Amkor. This end-user segment faces imperatives from AI chip ramps, where foundries like TSMC integrate FOWLP to stack HBM. Geopolitical controls further steer demand, with BIS export rules mandating secure chains that favor domestic partners, spurring foundry investments in co-packaged optics for data centers.

The U.S. advanced semiconductor packaging landscape features a mix of integrated giants and specialized OSATs, with competition centering on capacity scale and technology roadmaps.
Intel Corporation positions itself as a systems foundry pioneer, leveraging its Intel 18A process for embedded packaging in AI PCs. Additionally, the company has been investing in new establishments to bolster its advanced semiconductor packaging, for instance, as per the January 2024 press release, Intel established its new “Fab 9” facility in New Mexico, which formed a part of its USD 3.5 billion investment strategy to equip New Mexico with advanced semiconductor packaging technologies.
Amkor Technology specializes in outsourced assembly, with strengths in fan-out and test service. In October 2025, Amkor broke ground on a $7 billion Arizona campus, expanding from initial $2 billion plans to support TSMC partnerships, as stated in its investor update. This facility bolsters automotive volumes, prioritizing yield optimization.
