Wafer manufacturing

For the wafer manufacturing applications field, Tempress offers various processes to increase the wafer quality and value, such as annealing, wet/dry oxidation and LPCVD polysilicon. With these Tempress process solutions so-called SOI (Silicon-on-Insulator) and POI (Piezo-on-Insulator) wafers are produced. Such wafers are required for many innovative device architectures and future technological advances.  

Batteries/ EV

Driven by improving battery technology, Electric Vehicles (EV) have made their way into our day-to-day life and can be seen on the streets everywhere. To further increase the acceptance of EV, battery technology needs to evolve even more to improve vehicle range and decrease charging time. Tempress is supporting the battery industry with deposition solutions for massproduced, enhanced anode materials that improve performance and extend the battery lifetime.  

Internet of Things (IoT)

The digital interconnectivity of objects and devices and the use of data thereof is described as the Internet of Things (IoT). Tempress provides process steps, such as polyimide curing, to enable the manufacturing of ultra-low-cost chips. These chips may be used to trace everyday items like bottles and other packaging material throughout the supply chain from cradle-to-cradle. Furthermore, Tempress offers process solutions that are used by leading companies to produce chips applied in mobile phones and cars (5G/connectivity). 

Power devices

Power devices facilitate handling of high electrical currents and/or voltages with high efficiency. These devices play an essential role in the electrification of the world, and are employed in power transmission, renewable energy, automotive and many other industrial applications. Examples of such devices are diodes, thyristors, MOSFETs, and IGBTs. Tempress offers a wide range of processes that are used to produce power devices 


Semiconductor-based photonic devices deliver speed improvements, reduced power consumption over conventional technologies and introduce new sensor applications. Thanks to the hybrid properties, semiconductor-based photonic devices are expected to enable the next step in many applications. Examples can already be found in fiber-optic applications, (bio)chemical sensors and LIDAR.  

Tempress furnace systems are used in world-renowned institutes to produce and develop new photonic devices for future applications. Here, Tempress offers solutions for essential production process steps such as low-loss Nitride, Poly Silicon, Thick Oxide, and anneal processes.  


Microelectromechanical systems (MEMS) typically consist of components between 1 and 100 micrometers in size (i.e., 0.001 to 0.1 mm) and are commonly used in sensors such as accelerometers, gyroscopes, and barometers. MEMS manufacturing technology is also used in the high-end watch industry to create very small and precise mechanical parts that improve the precision of time measurement.  

Tempress has LPCVD (Nitride and low stress Nitride, surface treatment, POLY, TEOS), PECVD (SiN, SiOxN) as well as oxidation and anneal solutions for the MEMS industry that are widely used by major industry players and leading research institutes. 


Photovoltaic devices are widely used in the generation of electricity by converting sunlight into electrical power. Tempress has a long history of developing and delivering innovative, high-volume manufacturing furnaces for the solar market. Tempress has shipped more than 30 GW of diffusion furnace systems for Solar applications and has been a front runner with innovative technologies with a focus on n-type. Tempress was involved in development and industrialization of n-PERT, and TOPCon solar cells as used in leading modules at the time. Tempress specializes in P-diffusion, B-diffusion, p-, n- and undoped Poly-Si, SiNx, SiOxNy and AlOx deposition processes. These processes are performed using diffusion, LPCVD, ALD and PECVD.  

Life Science/MedTech 

When MEMS technology is combined with surface chemistry, devices in the field of molecular nanotechnology and microfluidics are created that allow for exiting new applications in life sciences, biotech and medtech. These technologies are used to produce biosensors, healthcare diagnostic devices, lab-on-a-chip and to improve sequencing technology. 

Tempress has deposition, LPCVD (Silanation, surface treatment, POLY, TEOS) and PECVD (SIN, SiOxN) as well as oxidation and anneal solutions for the Life Science and Biotech industry, proven by many leading research institutes.
