A new technique for manufacturing silicon nanowires on the surface of a conventional silicon wafer using ion-beam irradiation through a lithographic mask has been proposed. The conditions needed for synthesizing silicon oxide using the irradiation of the silicon substrate by protons with an energy of about 1 keV have been studied. The possibility of synthesizing silicon oxide in the region of the geometric shadow under the monocrystalline silicon nanowire has been demonstrated.
