A method of fabricating semiconductor fins, including, patterning a film stack to produce one or more sacrificial mandrels having sidewalls, exposing the sidewall on one side of the one or more sacrificial mandrels to an ion beam to make the exposed sidewall more susceptible to oxidation, oxidizing the opposite sidewalls of the one or more sacrificial mandrels to form a plurality of oxide pillars, removing the one or more sacrificial mandrels, forming spacers on opposite sides of each of the plurality of oxide pillars to produce a spacer pattern, removing the plurality of oxide pillars, and transferring the spacer pattern to the substrate to produce a plurality of fins.

The present invention relates to a semiconductor element and a method for manufacturing same, wherein the semiconductor element may comprise: a base element, an intermediate layer formed in at least one direction of the base element; and a metal layer formed on the intermediate layer in a direction opposite to the base element, and wherein a conductive filament may be formed inside the intermediate layer according to the application of a voltage to the intermediate layer.

The present inventive concept relates to an atomic layer deposition (ALD) method for forming an IGZO channel layer of a transistor device the method comprising: a deposition cycle step of performing a deposition cycle for depositing an IGZO channel layer on a substrate; and a repeat step of repeatedly performing the deposition cycle step until the IGZO channel layer is formed with a predetermined thickness, wherein in the deposition cycle step, the IGZO channel layer is formed by performing an indium oxide sub-cycle for depositing indium oxide (InO), a gallium oxide sub-cycle for depositing gallium oxide (GaO), and a zinc oxide sub-cycle for depositing zinc oxide (ZnO).
