Adhesives for advanced packaging: Optimize the power of your semiconductor chips and SMD assemblies with DELO

High-performance semiconductor chips are at the heart of modern technologies. They are indispensable in forward-looking areas such as artificial intelligence, autonomous driving, smart cities and robotics. Progress in miniaturization and improvements in component functionality depend heavily on the specifically optimized properties of the materials like the semiconductor adhesives used.

DELO specializes in the development of adhesives for semiconductor packaging. Our functional materials are suitable for a wide range of applications such as die attach, reinforcement (capillary underfill, corner fill, edge bond), the protection of semiconductor chips and CMOS image sensors with potting compounds or materials, for example, for glass lid bonding

Our materials enable efficient, CO2-reduced production processes and are optimally suitable for fully automated series production. 

Thanks to the special properties of DELO's semiconductor adhesives, you can increase the performance of your semiconductor packages. At the same time, our high-tech solutions create new possibilities in the field of heterogeneous integration and thus make a significant contribution to the further miniaturization.
