TILING OF SEEDS USED IN A CRUCIBLE FOR THE DIRECTIONAL SOLIDIFICATION OF SILICON COMPRISING SEEDS THAT ARE DISORIENTED WITH RESPECT TO THE ADJACENT SEED

摘要

The present invention relates to an organized assembly of adjacent silicon single crystals for the directional solidification of an ingot along a solidification direction, the oriented single crystals of which, observed over a section perpendicular to the solidification direction Z are such that the disorientation of an oriented single crystal with an adjacent single crystal is greater than 8°, the smallest angle between a normal to the joint separating the single crystal from an adjacent oriented single crystal and the directions 111 of said adjacent single crystal is greater than 4°, the smallest angle between the direction Z and the directions 100 of said single crystal is less than 25° and /or the smallest of the angles between the direction Z and the directions 111 of the single crystal is less than 10°, and the projection distance in a plane perpendicular to the direction Z, of the largest dimension of said single crystal, measured among the planes {111} and along the directions 110, is less than 40 mm.
