PURPOSE: A dot-size controlling method for a nano metal structure, a manufacturing method for the nano metal structure using the same, and an ion irradiation system for fin metal processing are provided to form nano-dots with desired shapes and sizes by implementing an ion irradiation process based on a threshold ion dose. CONSTITUTION: A threshold ion dose for target metal is determined based on the linear function of data with respect to the nano-dot size values of metal structures on a substrate. The nano-dot size values are varied according to the interval and the amount of ion irradiation. The amount of ion irradiation with respect to a metal layer is controlled in order to control the nano dot sizes of the metal structures on the substrate. The metal layer is eliminated.
Abstract:
A method for manufacturing a nano structure using a focused ion beam and an MRF(Magneto-Rheological Fluid) is provided to reduce a manufacturing process procedure by performing two stage nano structure manufacturing processes. A focused ion beam is irradiated on a part of the surface of a test piece(2) to implant ion into an ion implantation portion(4) of the test piece during a first stage nano structure manufacturing structure. Mechanical and physical properties of the ion implantation portion increases than those of an ion non-implantation portion(6) where the ion implantation is not performed. A fine structure of the test piece is processed by using an MRF during a second stage nano structure manufacturing process.
