Nickel-Platinum Target (NiPt Target) Description
Nickel-Platinum Sputtering Targets (NiPt Targets) are high-performance materials produced by precision alloying of Nickel (Ni) with Platinum (Pt) in specific ratios (e.g. Ni: Pt = 80:20 or custom ratios). Key properties include:
Highest purity: Metallic purity ≥99.95%, with the main impurities (e.g. Fe, Cu, C) controlled to <50 ppm, verified by Glow Discharge Mass Spectrometry (GDMS) and X-ray Fluorescence (XRF), to ensure a minimal risk of contamination during sputtering.
Excellent thermal stability: Melting point up to 1 455°C, thermal conductivity of ~90 W/(m-K) for high-performance sputtering scenarios, thus preventing cracking or delamination of the film due to thermal stresses.
Homogeneous microstructure: Grain size ≤10 µm, porosity <0.1% and surface roughness Ra <0.5 µm (chemically-mechanically polished) are controlled through hot isostatic pressing (HIP) and powder metallurgy processes to ensure sputtering rate and uniformity of layers.
Corrosion resistance: The addition of Platinum significantly improves the alloy's resistance to oxidation, acids, and alkalis, making it suitable for long-term use in harsh environments (e.g. acidic gases or oxidative high-temperature conditions).
