Silver Sintering Die Attach Paste Market Dynamics

Drivers

 Rising demand for high-power electronics in EVs and renewable energy

The growing shift toward electric mobility and renewable energy sources has amplified the demand for power semiconductor devices. In 2024, electric vehicles consumed over 136 metric tons of silver sintering die attach paste for their traction inverters and power control units. The ability of silver paste to withstand operating temperatures above 250°C and currents exceeding 600 A/mm² has made it a preferred choice for SiC-based MOSFETs and IGBTs. Solar inverters and wind turbine converters collectively utilized more than 72 metric tons of silver paste, with hybrid inverters increasingly using pressure-less sintered interconnects. The need for long-term reliability, especially in automotive and energy infrastructure, has been a central factor driving the demand.

Restraints

High cost and limited availability of high-purity silver

The production of silver sintering paste depends on high-purity silver powder, with a purity level of at least 99.99%. In 2024, the average cost of silver powder increased by 18%, placing upward pressure on paste formulation costs. With each kilogram of sintering paste requiring approximately 750 grams of silver, fluctuations in silver prices significantly affect production economics. Limited availability of ultra-fine silver particles, especially below 200 nm, has led to bottlenecks in meeting custom-order demand. More than 27% of small and mid-sized manufacturers reported delays in sourcing consistent quality silver powder during 2023–2024. Additionally, waste handling and recycling of used paste in production environments remain operational challenges.

 

Opportunities

 Expansion of SiC and GaN semiconductor fabrication

Wide-bandgap semiconductors such as silicon carbide (SiC) and gallium nitride (GaN) are gaining rapid traction in automotive and industrial electronics. In 2024, over 430 million SiC chips were packaged globally, of which 53% used silver sintering pastes for die attach processes. The construction of 19 new SiC fabs, particularly in Japan, China, and the United States, will generate an estimated demand of 220 metric tons of silver paste by 2026. GaN-based RF devices, used extensively in 5G base stations and radar systems, accounted for 11% of the market’s consumption in 2024. As the industry pivots toward higher efficiency and reliability, the use of sintered silver for thermal and electrical interconnects is projected to accelerate across advanced packaging nodes.

Challenges

 Equipment compatibility and sintering cycle limitations

Despite the advantages of silver sintering, integration with legacy packaging equipment remains a major challenge. More than 45% of existing semiconductor assembly lines lack the necessary equipment for achieving optimal sintering profiles, especially under controlled atmospheric conditions. Manufacturers require sintering ovens capable of reaching 250°C to 300°C with precise dwell times, typically over 10 minutes, to achieve full densification. Additionally, pressure sintering systems require up to 10 MPa force, which adds to the capital investment barrier. As of 2024, fewer than 3,000 global assembly lines were fully optimized for high-yield silver sintering processes. Cycle times, material waste during dispensing, and sensitivity to moisture exposure continue to hinder broader adoption.
