Semiconductor Device Having A Reduced Concentration Of Carbon Vacancies And Its Manufacturing Method

Abstract: The present disclosure relates to a semiconductor device (1) comprising at least one epitaxial layer (2) made from a first semiconductor material comprising carbon and having a [0001] crystallographic axis. At least one implantation area (4) is formed at a sidewall (3a) of the epitaxial layer (2), wherein a normal direction of the sidewall (3a) is perpendicular to the [0001] crystallographic axis. At least one part of the epitaxial layer (2) has a reduced concentration of carbon vacancy (VC) with respect to the first semiconductor material of the at least one epitaxial layer (2) as-grown. The present disclosure further relates to a method for manufacturing a semiconductor device (1), wherein ions are implanted through at least one sidewall (3a) of at least one epitaxial layer (2).
