PURPOSE: A nano-wire ink solution and a manufacturing method thereof are provided to control movement of the nano-wire by controlling fluid flow of the nano-wires. CONSTITUTION: A nano-wire ink solution comprises nano-wires in which diameter distribution shows two or more normal distributions. The nano-wire ink solution comprises a first nano-wire population and a second nano-wire population. The second nano-wire population shows bigger average diameter than the average diameter of the first nano wire population. The first nano-wire population has smaller volume% than volume % of the first nano-wire population. A manufacturing method of the nano-wire ink solution comprises the following steps: preparing nano-wires in which the diameter distribution shows two or more normal distributions; and dispersing the nano-wires. The first step comprises the following steps: preparing 1-15 volume% of the first nano-wire population having average diameter of 100-300 nano meters; and preparing the second nano-wire population having the average diameter of 400-700 nano meters.

PURPOSE: A method for aligning nano-wires is provided to effectively align the nano-wires based on hydrophilicity, hydrophobicity, and photo-sensitive patterns. CONSTITUTION: A method for aligning nano-wires includes the following: a photoresist pattern(620) with a hole structure is formed on the upper side of a substrate(610); a nano-wire aqueous solution is supplied to the hole structure; nano-wires(630) is aligned by evaporating the nano-wire aqueous solution; and the photo-sensitive patterns are eliminated. A material for the photo-sensitive is SU-8. The hydrophilicity and the hydrophobicity of the photo-sensitive patterns and the nano-wires are adjusted on the surface of the substrate.

Abstract:
PURPOSE: A method for manufacturing a single crystal silicon thin film using light irradiation is provided to easily transfer the single crystal silicon thin film to another substrate like a flexible substrate by removing an intermediate oxide layer of an SOI substrate with etchant and light irradiation. CONSTITUTION: An SOI substrate(104) laminated with a silicon oxide layer(102) and a single crystal silicon thin film(103) is prepared on a bulk substrate(101). An etchant or the steam of the etchant is applied to the single crystal silicon thin film. A micro lens array(50) is arranged on the single crystal silicon thin film. Light is irradiated to the single crystal silicon thin film. The silicon oxide layer is removed when the single crystal silicon thin film remains.
