The spirit of progress.

Our markets.

Tempress deposition and diffusion solutions are used by leading companies in the semiconductor and advanced materials industry. Applications range from wafer manufacturing to MEMS, optoelectronic chip and power semiconductor production. Our solutions also play into non-wafer applications such as production of nano-materials that enhance performance of cathodes for EV batteries or coatings for membranes to clean waste streams.


Diffusion processes are used in semiconductor manufacturing to modify the electrical properties of the wafer material, typically by introducing dopant atoms into the wafer material from a chemical vapor source or by annealing the crystal defects. Tempress offers a wide range of diffusion processes from high temperature annealing (up to 1365°C ), wet and dry oxidation and Phosphorus and Boron doping with POCI3 and BBr3, to lower temperature (<500°C) sintering, alloying and annealing with up to 100% H2.


Deposition (CVD/ALD) processes are used to produce (thin) films of high quality and high-performance solid materials on a wafer. Typical applications can be found in the production of integrated circuits (ICs), micromechanical structures (MEMS), photonic devices and photovoltaic (solar cell) systems. Tempress offers Low Pressure CVD (LPCVD), that reduces unwanted gas-phase reactions and improves uniformity of the film across the wafer, Plasma Enhanced CVD (PECVD), allowing deposition at lower temperatures with increased deposition rates and Atomic Layer Deposition (ALD) for producing very thin, conformal films with control of the thickness and composition of the films possible at the atomic level.

Tempress offers a multipurpose thermal processing platform that enables you to use a wide range of (semiconductor) diffusion and deposition technologies.
