Abstract:
1. A method for forming a pattern, which comprises the steps of: (a) providing a substrate having a sacrificial layer made of a first material, partially or totally formed on the substrate; (b) forming pattern grooves, which are free from the first material and have a line width of a first resolution or lower, on the sacrificial layer by using a first means of irradiation of focused energy beams; (c) filling the pattern grooves with a second material to a second resolution, which is lower than the line width of the pattern grooves formed in step (b), by using a second means of ink-jet; and (d) removing the first material present in a remaining sacrificial layer by way of irradiation or heating, wherein the first material has a threshold fluence of less than a threshold fluence of the second material, the first material is removed in step (d) under a dose ranging from the threshold fluence of the first material to the threshold fluence of the second material, and the pattern is formed on the substrate by the second material.
