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

There are a device and method for protecting semiconductor material, wherein semiconductor material is processed on a surface of stabilized ice made from ultrapure water and particles of semiconductor material.

Method and device for processing semiconductor material

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.

Air separation of polysilicon

A method and a device for the separation of semiconductor material has the separation procedure carried out on screens coated with ice made of ultrapure water, optionally mixed with particles of semiconductor material. During the separation, the screens are sprayed with ultrapure water and the screen holes are cut free.

Separation of semiconductor material

A device for protecting semiconductor material includes a support and a surface made of ice formed from ultrapure water. Semiconductor material is situated on this support surface.

Crushing of silicon on ultrapure ice

An apparatus for the optoelectronic classification of semiconductor materials, has a separating device 2 and a slide face 3, the angle of the slide face 3 to the horizontal being adjustable, and the separating device 2 and the slide face 3 each having a surface made of the semiconductor material to be separated. There is a radiation source 5, through the beam path of which the material to be classified falls, and a shape recognition device 6, which transmits the shape of the material to be classified to a control unit 7, which controls at least one diverter device 8.
