Claim 0:
1. A device for manufacturing a crystal from a melt of a raw material, comprising:
a crucible for receiving the melt having a first section including a first cross-sectional area and having a second section for receiving a seed crystal and including a second cross-sectional area, wherein the second cross-sectional area is smaller than the first cross-sectional area and the first and the second section of connected with each other directly or via a third section which tapers from the first to the second section, in order to allow a crystallization starting from the seed crystal within a directed temperature field into the solidifying melt,
wherein the first section of the crucible has a central axis, and the second section is arranged to be laterally offset from the central axis of the first section; and
wherein the second section has an extended length along a direction of the central axis between 50 and 90 mm and an inner diameter that is less than 15 mm.
