A charging material made from semiconductor material, is used for charging or recharging a melting crucible during the Czochralski crucible-pulling process. This charging material has a polycrystalline semiconductor rod, which at one end has a groove, and a monocrystalline semiconductor rod, which at one end has a tongue, which rods are coupled by means of a tongue-and-groove connection. There is also a holding system for holding a polycrystalline silicon rod during the Czochralski crucible-pulling process or the float zone process, which has a tongue-and-groove connection between the polycrystalline semiconductor rod, which at one end has a groove, and a monocrystalline semiconductor rod, which at one end has a tongue.

Charging material and holding system for the charging material

A method for conveying silicon fragments has the silicon fragments being conveyed over a conveyor surface, which is made from hyperpure silicon. There is a vibrating conveyor, and during the conveying, the sharp edges of the silicon fragments are rounded and mechanical-physical decontamination takes place. The vibrating conveyor has a conveyor surface which is made from hyperpure silicon. A second vibrating conveyor unit has a conveyor surface which is made from hyperpure silicon and has passage openings therethrough.

Vibrating conveyor and method for conveying silicon fragments

A method is for processing semiconductor material, in which one or more shock waves generated using a transducer are transmitted through a liquid medium to semiconductor material in rod form. The transducer is at a distance of from 1 cm to 100 cm from the semiconductor material, and the shock waves have a pulse energy of from 1 to 20 kJ and a pulse rise time to the energy maximum of from 1 to 5 &mgr;s.

Method for processing semiconductor material

A method of producing a polycrystalline silicon rod is by depositing silicon on a carrier rod and cutting to size a molding produced in the process. In order that the silicon rod is given a rod end which is free of cracks and flaking, the rod is rotated about its longitudinal axis and cut through with a parting tool.

A device for the optoelectronic classification of semiconductor materials, which has an identifying device,that forwards the morphology of the product,to be classified to an evaluating device,which evaluates the data.

Semiconductor material classification device

A separation device which has at least one blower device and at least one deflector device can be used to separate large fragments of semiconductor material from small fragments of semiconductor material.
