Material & Engineering Overview

High-purity scandium (Sc, CAS 7440-20-2) 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.

Distilled high-purity scandium targets enable co-sputtering with aluminum to boost the d33 piezoelectric coupling coefficient of Al1-xScxN up to 5×. Each scandium 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.

Standard Shipment Documentation: Manufacturer Lot COA (GDMS or ICP-OES trace metallic impurity assay in ppm for Sc, bulk density), dimensional inspection, and indium-bond check if bonded.

What to Specify in Your Quote Request

Specify scandium purity grade (3N5 (99.95%) / 4N (99.99% REM)), 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.

Technical & Procurement FAQ

What purity grade of scandium (Sc) sputtering target should I select?
Standard 3N5 (99.95%) purity suits general metallization, hard coatings, and adhesion/barrier layers, while higher 4N5–5N grades are recommended for active semiconductor junctions, low-resistivity interconnects, and quantum/optical research.
Should my scandium sputtering target be bonded to a copper backing plate?
Distilled high-purity scandium targets enable co-sputtering with aluminum to boost the d33 piezoelectric coupling coefficient of Al1-xScxN up to 5×. Bonding with metallic indium to an OFHC copper backing plate is recommended for brittle compositions, thin discs, or high-power-density runs (keep cooling water at 18–22 °C so the indium bond stays below 120 °C).
What batch certification ships with TB-PVD-SC?
Every scandium target ships vacuum-sealed in an argon/moisture barrier bag accompanied by the producing mill's lot Certificate of Analysis reporting elemental purity and trace metallic impurities in ppm.
