More About Ta/Al Evaporation Material

Tantalum Aluminum Evaporation Materials are specialized coatings derived from a blend of tantalum and aluminum, commonly employed in vacuum evaporation procedures. These materials find diverse applications, notably in the semiconductor industry for thin film deposition, optical coatings, and research endeavors.

The amalgamation of tantalum and aluminum in these evaporation materials offers distinctive advantages owing to their unique physical and chemical attributes. Tantalum boasts a remarkable high melting point surpassing 3,000°C, exceptional corrosion resistance, and heightened thermal stability. On the contrary, aluminum, with its lower melting point, contributes commendable electrical conductivity, enhancing the stability and adhesion of the resultant film.

The synergy between tantalum and aluminum leads to a film with enhanced properties compared to each material in isolation. The ratio of tantalum to aluminum can be fine-tuned to fulfill specific criteria, such as achieving the desired film thickness, bolstering adhesion strength, or optimizing electrical conductivity.

Description

High-purity evaporation materials play a huge role in deposition processes to ensure high-quality deposited films. Tantalum(Ta), a transition metal classified on the Periodic Table, falls under refractory metals, renowned for their exceptional corrosion resistance. Possessing a melting point of 3,017°C, a density of 16.6 g/cc, and a vapor pressure of 10-4 Torr at 2,590°C, tantalum exhibits a metallic grey-blue color and shares chemical properties akin to niobium. Its non-toxic nature makes it a prime choice for surgical implants, while its application extends to the electronics industry, where it serves as a capacitor. Tantalum can be alloyed with other metals to enhance strength and durability. In vacuum evaporation, tantalum and its alloys and compounds produce semiconductors, optical coatings, magnetic storage media, and coatings with wear and corrosion resistance.

Tantalum is nearly impossible to deposit by thermal evaporation due to the high power required for the material to evaporate. E-beam evaporation or magnetron sputtering are the recommended methods for tantalum deposition. Tantalum is designated as ‘excellent’ for e-beam evaporation. Nevertheless, this process poses challenges and necessitates meticulous monitoring throughout.
