Abstract
The present disclosure relates to a method of forming a semiconductor device comprising horizontal nanowires. The method comprises depositing a multilayer stack on a substrate, the multilayer stack comprising first sacrificial layers alternated with layers of nanowire material; forming at least one fin in the multilayer stack; applying an additional sacrificial layer around the fin such that a resulting sacrificial layer is formed all around the nanowire material; and forming a nanowire spacer, starting from the resulting sacrificial layer, around the nanowire material at an extremity of the nanowire material. The present disclosure also relates to a corresponding semiconductor device.
