Tantalum for
Semiconductors
Global Advanced Metals (GAM) is the best choice for tantalum for thin films via physical vapor deposition (PVD) in semiconductor processes. GAM is a fully integrated producer of tantalum sputtering materials, serving the demanding semiconductor, capacitor, aerospace and medical industries for over 70 years.
Large, Reliable Tantalum Supply
Leader in Conflict-Free initiatives, GAM has a diverse, reliable and economical supply of tantalum raw materials:
- Rights to the large Western Australian raw material base
- Unique rights to tantalum by-product from rapidly growing lithium production
- Extensive network of recycle streams
Creating Value for the Semiconductor Industry
- GAM provides a competitive alternative to a limited supply chain
- Stable ore sourcing eliminates supply chain reliability risk
- Reduces risk associated with market price fluctuations
- GAM tantalum is qualified for advanced geometries in PVD applications
Microstructural uniformity
Advanced Tantalum Technology
- High purity ingot with consistent chemistry provides best performance on ship to control requirements and input to target plate processing
- Target plates with state-of-the-art purity, grain size and texture produced from the best powders
- High deformation processing: Uniform texture with minimal banding at the mid-plane
- Better target performance – Microstructural uniformity provides consistent deposition through the target’s life and better tantalum film thickness control
- Process consistency – Electron Back-Scatter Diffraction (EBSD/OIM) analysis shows a high degree of uniformity in both grain size and orientation from plate to plate
