What Are Semiconductor Packaging Materials?
Semiconductor packaging materials are a class of electronic solutions used to form the connection of the IC chip to the package substrate, another package or directly to the printed circuit board. These materials are critical to semiconductor wafer-level packaging processes, heterogeneous integration, and 3D integration technologies.

Designed for the Heterogeneous Integration Roadmap
Today's leading-edge electronics are expected to have more functionality packed in a smaller form factor, using less power, while improving performance and reliability. These devices power mobile devices, high performance computers, the IoT, memory, automotive electronics, the 5G networks of the future and more. They rely on semiconductor packaging materials that follow the Heterogeneous Integration Roadmap (HIR) and are designed to meet these stringent requirements.
