Product Series
Tantalum Target
Product Introduction
Tantalum has a melting point of 2,996°C, a density of 16.68g/cm3, and a thermal conductivity (at 25°C) of 54 (W M K). Tantalum has high electrical conductivity, high thermal stability and barrier effect against foreign atoms. Therefore, sputtering coating technology is used to coat the tantalum film on integrated circuits, which prevents the diffusion of copper into the base silicon. Tantalum targets are mainly used in semiconductor and optical fields. Our tantalum targets are produced from tantalum ingots prepared by EB electron bombardment by a combination of rolling and annealing. The target produced by this technology has an excellent internal structure, as well as a uniform crystal layout, texture and energy distribution.
