Purpose-engineered materials for semiconductor, display, and precision electronics manufacturing — sourced globally, delivered locally.
Murua Korea supplies advanced materials across three core categories, each serving critical applications in Korea's advanced manufacturing supply chains. Material specifications and availability are discussed on a case-by-case basis to match customer requirements.
6N / 7N Grade — ≥99.9999% Purity
Ultra-high-purity copper powder is foundational to next-generation semiconductor packaging and interconnect technologies. As advanced packaging architectures demand higher interconnect density and reliability, the purity and morphological consistency of copper materials become critical manufacturing parameters.
At 6N and 7N purity levels, impurity concentrations are reduced to parts-per-billion, directly impacting TSV electrical stability, thermal dissipation performance, signal integrity, and long-term device reliability — factors that are increasingly critical as AI and HPC workloads drive demand for advanced packaging solutions.
Minimized impurities ensure consistent conductivity and reduced contact resistance in TSV and microbump structures.
High-purity copper enables superior heat dissipation in thermally demanding 3D package architectures.
Ultra-pure interconnect materials support high-frequency signal transmission in advanced logic and memory devices.
Consistent material quality contributes to long-term reliability in mission-critical semiconductor applications.
