endowed halbleiterscheibe from zonengezogenem semiconductor material and method for manufacturing the halbleiterscheibe

摘要

the subject of the invention is also a process for the production of a doped halbleiterscheibe by zonenziehen a einkristalls and chopping of the einkristalls, with the zonenziehen a with an induction coil generated melt with a dotierstoff doped with at least one rotating the magnetic field exposed and solidification is broughtthe solidification of the melt and the single crystal is rotated, and the single crystal and the magnetic field with gegensinniger rotation can be rotated and the magnetic field of a frequency of 400 to 700 hz possesses.
