Market Drivers

AI and data centre compute demand push advanced bonding

A primary driver for the high-value bonding segment is the explosive demand for AI and data-centre computing. The need for AI accelerators and memory stacks, like HBM, requires multi-die integration and fine-pitch interconnects, which are enabled by advanced bonding techniques.

• For example, in February 2025, Technology Holding projected its advanced packaging and testing revenue to more than double in 2025, to approximately USD 1.6 billion, driven by high demand for AI chips.

This flow-through effect across the supply chain, as chip designs shift toward heterogeneous integration, is a significant driver for the bonding market.

On-shoring and government incentives accelerating capacity builds

Governments across the world are providing financial incentives to accelerate the development of local semiconductor ecosystems.

• For instance, in July 2024, the U.S. Department of Commerce signed a Preliminary Memorandum of Terms with Amkor Technology for up to USD 400 million in proposed grants to fund a planned USD 2 billion advanced semiconductor packaging facility in Peoria, Arizona.

This public funding directly increases the demand for bonding equipment for new or expanded facilities, and it reduces the financial risk for companies to invest in expensive, advanced bonding tools. This is driving a wave of capacity expansions and strategic partnerships, which boost demand for both legacy and advanced bonders across the supply chain.

Market Restraint

High capital cost and process complexity for advanced bonders

The high capital cost and technical complexity of next-generation bonders represent a significant market restraint. Advanced hybrid and thermo-compression bonders are extremely expensive, with leading-edge systems costing over USD 12 million per unit. This upfront capital expenditure, along with the need for specialised cleanrooms and extensive process R&D, creates a high barrier to entry for smaller OSATs. Trade tensions further complicate the supply of equipment and materials, increasing lead times and project risk. These factors collectively temper the broad, rapid adoption of advanced bonding.

Market Opportunity

Large Outsourced Semiconductor Assembly and Test (OSAT) companies and Integrated Device Manufacturers (IDMs) are making substantial capital investments and forming strategic alliances to expand their advanced packaging capabilities. This directly fuels the purchase of bonding equipment and the adoption of new processes.

• For instance, in April 2025, Amkor Technology entered into a Strategic Partnership with Intel focused on Embedded Multi-Die Interconnect Bridge (EMIB) assembly. This collaboration aims to enhance the availability of the EMIB technology ecosystem and significantly expand Advanced Packaging capacity in Korea, Portugal and the United States.

Such projects, often supported by government incentives, require a mix of legacy high-volume bonders and sophisticated hybrid bonders, boosting the overall market.

Regional Analysis

The Asia-Pacific region dominates the semiconductor bonding market due to its established concentration of OSATs, foundries, and end-device manufacturing, as well as the largest installed base of advanced packaging lines. This concentration drives high annualised demand for everything from wire bonders for legacy packages to capital-intensive hybrid bonders for AI stacks. Korea and Japan are strong in memory and materials, while China continues to scale packaging capacity to serve a vast consumer and telecommunications market. Even as Western governments subsidise local capacity making it the largest base of bonded packaging volumes and advanced packaging.

North American Market Trends

North America is the fastest-growing region for semiconductor bonding in 2025, propelled by large, government-backed initiatives and a wave of announced packaging projects that specifically target on-shore advanced packaging capability.
