Vacuum-melted high-purity germanium (Ge, CAS 7440-56-4) planar magnetron sputtering targets in 5N (99.999%) / 6N (99.9999%) Intrinsic or Ga/Sb-Doped grades for semiconductor, optical, and research PVD.
High-purity germanium (Ge, CAS 7440-56-4) planar sputtering targets are consolidated by vacuum melting or hot isostatic pressing and thermomechanically processed to achieve fine, equiaxed microstructure and ≥99.5%–100% relative density. Controlled grain uniformity and ultra-low dissolved gas content (O, N, H, C) ensure stable DC, pulsed-DC, RF, and HiPIMS plasma impedance with minimal droplet or particle generation across the target erosion track.
Brittle zone-refined germanium targets should be indium-bonded to an OFHC copper backing plate to prevent thermal cleavage during RF or DC runs. Each germanium target is precision-machined to fit 1-inch (25.4 mm), 2-inch (50.8 mm), 3-inch (76.2 mm), 4-inch (100/101.6 mm), or custom rectangular magnetron cathodes, supplied monolithic or indium-bonded to an OFHC copper backing plate, and vacuum-sealed with a batch GDMS or ICP-OES Certificate of Analysis.

Specify germanium purity grade (5N (99.999%) / 6N (99.9999%) Intrinsic or Ga/Sb-Doped), target diameter and thickness (e.g., Ø 2.00" × 0.125" or 0.250"), flat edge vs. stepped clamp lip, magnetron gun model, and whether monolithic or indium-bonded to an OFHC copper backing plate is required.
Include target quantity, destination country/postal code for express air freight calculation, and any special cleanroom bagging or certification requests.
