Semiconductor Packaging Materials That Span the Spectrum

A Broad Portfolio of Materials for All Types of Advanced Semiconductor Packages

With more than 50 years invested in technology development, DuPont Electronics & Imaging understands the needs in the market and has developed a broad portfolio of semiconductor packaging materials for a range of technology areas.

We draw from other areas of the company to leverage expertise across the entire electronics manufacturing supply chain.

Through close relationships with leading-edge manufacturers, we develop new materials to meet ever changing requirements, from workhorse packages like flip-chip technologies to emerging technologies like fan-out wafer level packaging and through silicon vias (TSVs). We are technology leaders in electroplating materials used for underbump metallization (UBM), copper redistribution layer (RDL), Cu pillars, and solder bumps, along with polymers and dielectrics for RDL. Other advanced materials include photoresists and TSV fill.

  • Semiconductor packaging materials are a class of electronic solutions used to form the connection of the 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.

  • 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.
