tantalum disc


rotatable sputtering targets

ASTM B708 Standard Tantalum Sputtering Target , 99.95% 3N5 Purity , Disc Target





Tantalum sputtering target is mainly applied in semiconductor industry and optical coating industry. We manufacture various specifications of tantalum sputtering targets upon the request of customers from semiconductor industry and optical industry through vacuum EB furnace smelting method. By wary of unique rolling process, through complicated treatment and accurate annealing temperature and time, we produce different dimensions of the tantalum sputtering targets such as disc targets, rectangular targets and rotary targets. Moreover, we guarantee the tantalum purity is between 99.95% to 99.99% or higher; the grain size is below 100um, flatness is below 0.2mm and the Surface Roughness is below Ra.1.6μm. The size can be tailored by the customers’ requirements. We control our products quality through the raw material source till the whole production line and finally deliver to our customers in order to make sure you purchase our products with stable and same quality each lot.


We are trying our best to innovate our techniques, enhance the product quality, increase the product utilization rate, lower down the costs, improve our service to supply our customers’ with higher quality products but lower purchase costs.
