This robust support system significantly facilitates the realization of next-generation high-performance and miniaturized semiconductor devices.
Technical Details
Henkel’s advanced semiconductor packaging materials portfolio incorporates distinctive technologies such as:
- Lid and Stiffener Adhesives: These provide high bond strength and thermal stability, maintaining the structural integrity of packages while securely fixing components like heat spreaders.
- EMI Shielding Materials: Offering thin yet effective metallic coatings or composite materials, these prevent electromagnetic interference between adjacent components in increasingly dense devices, protecting signal integrity.
- Liquid Compression Molding (LCM) Solutions: Enabling IC encapsulation, gap filling, and overmolding of stacked memory chips at wafer or panel level, which enhances manufacturing efficiency and package reliability.
- Underfills: In flip-chip and BGA packages, underfills mitigate stress induced by thermal cycling and enhance the mechanical reliability of solder bumps, thereby extending device lifespan.
Each of these materials is optimized to address specific packaging challenges, and their synergistic application enhances overall packaging performance.
Background & Context
The semiconductor industry, facing the limits of Moore’s Law, is shifting towards innovative packaging technologies to achieve performance gains. 2.5D and 3D packaging are key to integrating multiple chips vertically or horizontally, improving data transfer speeds, reducing power consumption, and miniaturizing form factors. However, these complex structures introduce new challenges, such as thermal stress during manufacturing processes and heat dissipation during operation. Material suppliers like Henkel play a crucial role in the semiconductor ecosystem by providing high-performance adhesive and encapsulant materials to overcome these technical barriers.
Strategic Significance & Outlook
Henkel’s advanced semiconductor packaging material solutions provide an essential technological foundation for future high-growth applications such as AI accelerators, High-Performance Computing (HPC), 5G communication, and autonomous driving systems. The continuous evolution of these material technologies will enable further miniaturization, enhanced functionality, and improved reliability of devices, driving innovation across the entire semiconductor industry. Future focus is expected to be on developing new materials that minimize coefficient of thermal expansion (CTE) mismatch, boost thermal conductivity, and improve manufacturing process compatibility. Henkel plans to intensify its R&D investments in this area, contributing to the realization of next-generation electronic devices.
