Tantalum targets are sputtering targets made from high-purity tantalum (Ta) metal. Characterized by high purity, uniformity, and density, tantalum targets are essential for semiconductor fabrication, precision optical coatings, and advanced electronic device manufacturing. Tantalum performs stably under high vacuum conditions and is resistant to oxidation, making it widely used in the preparation of functional films.

Excellent Features of Tantalum Target

• High Purity:Typically, the purity is ≥99.99%, ensuring stable electrical and optical performance of the films.

• Uniformity: Tantalum targets must have a uniform microstructure to ensure consistent material distribution during the thin film deposition process.

• High Density: Uniform density is crucial to ensure stability during the deposition process.
