VD0534 Aluminum (Al) Evaporation Materials

Introduction

Aluminum (Al) Evaporation Materials are among the most widely used source materials in physical vapor deposition (PVD) processes, particularly thermal evaporation and electron-beam evaporation. Owing to aluminum’s excellent electrical conductivity, high reflectivity, and strong adhesion to a wide range of substrates, Al evaporation materials are essential in semiconductor fabrication, optical coatings, display technologies, and decorative applications. Their stable evaporation behavior and cost-effectiveness make them a foundational material for both industrial production and research environments.

Detailed Description

Aluminum evaporation materials are produced from high-purity aluminum refined through vacuum melting and controlled solidification processes to minimize impurities and dissolved gases. This ensures clean evaporation, reduced spitting, and consistent film quality during deposition.

Aluminum is especially valued for its relatively low melting point compared with refractory metals, allowing efficient thermal evaporation while remaining fully compatible with electron-beam evaporation for higher deposition rates and precise thickness control. During evaporation, aluminum forms smooth, continuous films with excellent step coverage and strong adhesion to substrates such as glass, silicon, polymers, and ceramics.

Al evaporation materials are commonly supplied in forms such as pellets, granules, wire, shots, and custom-cut pieces to match different evaporation sources, including boats, crucibles, and e-beam hearths. Controlled geometry and surface cleanliness help achieve stable evaporation rates and uniform film thickness, which are critical for high-throughput and multilayer coating processes.

Applications

Aluminum evaporation materials are widely used in the following applications:

• Semiconductor devices: Metallization layers, electrodes, and interconnects

• Optical coatings: High-reflectivity mirrors and reflective layers

• Display technologies: Conductive and reflective films in LCD and OLED systems

• Decorative coatings: Bright metallic finishes with corrosion resistance

• Packaging films: Barrier and reflective layers for flexible packaging

• Research & development: Thin-film studies and prototype device fabrication
