Crystal growth is a significant step for the semiconductor industry as well as for optical applications and solar industries. Sapphire single crystals are used for high power laser optics, high pressure components and substrates for LEDs. Silicon single crystals are the principal components of most semiconductor devices such as integrated circuits, microchips or solar cells.
Because of the high temperatures (up to 2.000°C) and harsh chemical environments occurring in this process, component parts of the crystal growth chamber must be made from
molybdenum or tungsten. The combination of high performance and extensive design possibilities makes our products the ideal choice for crystal growth components. By establishing industrial and scientific partnerships to develop new technologies, we continuously set new standards for the industry, and ensure that cutting-edge solutions continue to be developed for growth markets around the world.
