Tempress - BBr3 Diffusion Furnace System

Tempress is world market leader in the production of diffusion furnace systems for Boron diffusion (BBr₃). With 1.5 GW_p installed base, we are a valuable partner for the n-type solar cell manufacturing industry. For p-type surface doping of n-type  silicon, BBr₃ diffusion is one of the most simple and cost-effective solutions. BBr₃ diffusion offers an integrated solution of deposition of a BSG diffusion source layer and actual thermal diffusion of boron from this layer into the silicon. Tempress BBr₃ diffusion systems are designed and built based on many years of semiconductor and solar photovoltaic industry experience.
