The Science Behind Thin-Film Materials

Thin-film deposition involves creating layers with thicknesses ranging from a few nanometers to micrometers. The material properties of the films depend heavily on the input materials’ composition, purity, and structure. Technical specifications critical for customized materials include:
Purity Levels: Semiconductor applications often require sputtering targets with purity levels exceeding 99.999% (5N) or higher to prevent defects in chips or memory devices.
Grain Size and Density: Fine-grain targets with high-density compaction improve film uniformity and reduce particle generation during deposition. Studies have shown that densification via hot isostatic pressing (HIP) enhances sputtering target performance​.
Oxidation Resistance: Materials like titanium-aluminum nitride (TiAlN) provide enhanced oxidation resistance for high-temperature coatings, essential for aerospace and automotive industries.

Technical Customization by Industry

Semiconductors: High-purity aluminum, copper, and tantalum sputtering targets are integral to creating interconnects and transistor layers. For example, tantalum targets are used for barrier layers due to their high melting point (2996°C) and superior adhesion properties. A custom alloy such as Al-Cu ensures improved electromigration resistance, enhancing device reliability.
Optical Coatings: Evaporation materials like magnesium fluoride (MgF₂) or zirconium dioxide (ZrO₂) offer high refractive indices and excellent transparency for anti-reflective coatings in the 400-700 nm range. Such materials, when optimized with AR coatings, can achieve transmission efficiencies of >95% for specific wavelength ranges.
Renewable Energy: Thin films for solar cells often use sputtering targets made of copper indium gallium diselenide (CIGS) or cadmium telluride (CdTe). These materials, with absorption coefficients >10⁵ cm⁻¹ in the visible spectrum, enable highly efficient light harvesting. Customization ensures precise stoichiometry to optimize efficiency and stability.

Aerospace and Defense: Materials such as yttria-stabilized zirconia (YSZ) are employed for thermal barrier coatings. Custom tailoring the Y₂O₃ content (typically 8-12 wt%) enhances thermal cycling resistance, critical for jet engine components exposed to extreme temperatures​.

Data-Driven Customization

At Tinsan Materials, we rely on industry data and advanced material characterization to deliver solutions that meet technical demands. For instance:
Thermal Expansion Coefficients: Matching the substrate’s thermal expansion is critical. Materials like molybdenum (Mo) or tungsten (W) offer low coefficients (5.4 and 4.5 µm/m·K, respectively) for applications requiring thermal stability.
Electrical Resistivity: Custom alloys with tailored resistivity (e.g., 1.68 µΩ·cm for high-purity copper) ensure optimal conductivity in microelectronic applications.
