Abstract

Disclosed is a process for manufacturing a deep junction electronic device including steps of: b) Depositing a layer of non-monocrystalline semiconductor material on a plane surface of a substrate of a monocrystalline semiconductor material; c) Incorporating inactivated dopant elements prior to step b) into said substrate (1) and/or, respectively, during or after step b) into said layer, so as to form an inactivated doped layer; d) Exposing, an external surface of the layer formed at step b) to a laser thermal anneal beam, so as to melt said layer down to the substrate and so as to activate said dopant elements incorporated at step c); e) Stopping exposure to the laser beam so as to induce epi-like crystallization of the melted layer, so that said substrate and/or, respectively, an epi-like monocrystalline semiconductor material, comprises a layer of activated doped monocrystalline semiconductor material.
