Gold Bonding Innovation: TANAKA’s AuRoFUSE Transfer Tech Breakthrough

TANAKA’s new AuRoFUSE gold bump transfer tech revolutionizes semiconductor bonding, enabling complex chip structures and boosting manufacturing flexibility and efficiency.

Gold Bump Transfer Technology Revolutionizes Semiconductor Bonding

TANAKA PRECIOUS METAL TECHNOLOGIES Co., Ltd. has introduced a groundbreaking gold bump transfer technology for its sintered gold bonding system, AuRoFUSE™ Preforms. Announced on March 3 in New Delhi, this innovation enables gold bumps to be applied to semiconductor chips and substrates with complex structures — a vital development for advanced electronics manufacturing.

This strategic development promises enhanced manufacturing flexibility and scalability by overcoming previous limitations in gold bump application.

Transfer Technology Enables Complex Structures

Previously, gold bumps were formed directly on semiconductor chips or substrates, restricting applications on complex shapes such as protrusions and open holes. TANAKA's new method forms bumps on a separate transfer substrate, then transfers them to the target locations.

This approach eases bonding on intricate chip designs and delicate substrates that are sensitive to photolithography or chemical processes.

• Gold bumps are formed in silicon substrate openings to prevent drop-offs during handling.
• Heat treatment causes slight shrinkage, creating a gap that facilitates easy bump extraction with vertical force.

How will this innovation impact your chip design or manufacturing strategy?

Enhances Manufacturing Precision and Yield

By separating bump formation from the target substrate, TANAKA reduces variability and damage risks inherent in direct bump formation. This method supports substrates that are prone to damage from resist stripping solutions used in photolithography.

The technology expands semiconductor bonding possibilities while maintaining high precision and reliability.

• Enables bonding on substrates with inconsistent resist heights or delicate open holes.
• Minimizes defects from traditional direct bump formation techniques.

What advantages could this technique provide your production quality and cost control?

Strategic Impact on Semiconductor Industry

TANAKA's innovation corresponds to a rising demand for semiconductor devices with complex geometries and higher integration levels. The technology aligns with industry trends focused on miniaturization and performance improvement.

It positions TANAKA as a key enabler for next-generation semiconductor packaging solutions.

• Supports cutting-edge semiconductor substrates used in advanced electronics.
