METHOD FOR OBTAINING LAMINAS MADE OF A MATERIAL HAVING MONOCRYSTALLINE STRUCTURE

摘要

A method is described for obtaining a plurality of laminas, made of a material having monocrystalline structure, from an ingot made of the material having monocrystalline structure, the ingot having a distal end and an axis of symmetry (X), the method comprising: creating, in the ingot by use of a pulsed laser beam, a plurality of sacrificial layers with modified crystalline structure, the plurality of sacrificial layers being distributed along the axis of symmetry (X), the plurality of sacrificial layers dividing the ingot in a plurality of intermediate layers with altered thermal coefficient; and thermally causing the sequential or simultaneous breakage of the sacrificial layers to produce the plurality of laminas made of a material having monocrystalline structure.
