Crystal Growing

 

Crystal Growing Systems GmbH (CGS) in Asslar is one part of the division for manufacturing crystal growing equipment within the PVA TePla Group and was established in August 1999 in Hanau emerging from the crystal growing division of Leybold Systems GmbH.

For decades CGS has been designing and producing crystal growing equipment for the production of silicon crystals, and as a technologically leading producer CGS is one of the most important in its field worldwide.

PVA Tepla Danmark in Frederikssund is another part of the crystal growing systems division within the PVA TePla Group since May 2004. It has emerged from the former floatzone division of Haldor Topsoe A/S.

The floatzone technology of PVA Tepla Danmark was developed over decades as a special method of growing ulta-pure and oxygen-free silicon crystals for power electronics applications.

 

 

 

 

Crystal Pulling Equipment (CZ)

	For decades CGS has been designing and producing crystal growing equipment for the production of silicon crystals, and as a technologically leading producer CGS is one of the most important in its field worldwide.

	Typ EKZ 2700 These equipments combine proven mechanical elements with innovative elements for process control. The two plant types differ primarily in the design of the crystal drive unit (shaft/cable) and are used for the production of crystals with up to 6”  in diameter. The dimensions of these furnaces allow ... more

	Typ EKZ 3500 The EKZ 3500/200 is used to produce crystals of up to 200mm in diameter. The typical batch weights range between 120 and 150kg, depending on the hot zone installed and the use of feeder for increasing the batch weight. The crystal lengths obtainable from such batch sizes measure about 1.5m in the cylindrical portion.... more

	Multi Crystalizer   Vacuum furnace designed for directional solidification (based on Vertical-Gradient-Freeze Process) of multi-crystalline solar silicon ingots for photovoltaic wafer production ... more
