Abstract:
1. An insulation pattern-forming method comprising: forming a first organic pattern on a substrate, the first organic pattern comprising: a first acid generator and a first resin which comprises a first acid-labile group; insolubilizing the first organic pattern to a first organic solvent in a first insulating material by heating, by coating with a cured resin film or by a combination thereof, to provide a first solvent-insolubilized organic pattern, the first insulating material comprising a first polysiloxane and the first organic solvent; filling a space defined by the first solvent-insolubilized organic pattern with the first insulating material; exposing an upper surface of the first solvent-insolubilized organic pattern, after the space defined by the first solvent-insolubilized organic pattern is filled; forming a second organic pattern that comes in contact with the upper surface of the first solvent-insolubilized organic pattern, the second organic pattern comprising: a second acid generator and a second resin which comprises a second acid-labile group; insolubilizing the second organic pattern to a second organic solvent in a second insulating material by heating, by coating with a cured resin film or by a combination thereof, to provide a second solvent-insolubilized organic pattern, the second insulating material comprising a second polysiloxane and the second organic solvent; filling a space defined by the second solvent-insolubilized organic pattern with the second insulating material; exposing an upper surface of the second solvent-insolubilized organic pattern, after the space defined by the second solvent-insolubilized organic pattern is filled; exposing entire surfaces of the first solvent-insolubilized organic pattern and the second solvent-insolubilized organic pattern to light, such that the first acid-labile group and the second acid-labile group are dissociated by an acid generated by the first acid generator and the second acid generator to solubilize the first solvent-insolubilized organic pattern and the second solvent-insolubilized organic pattern in an alkaline developer and that a first solvent-insolubilized-alkaline-solubilized organic pattern and a second solvent-insolubilized-alkaline-solubilized organic pattern are provided, after the space defined by the second solvent-insolubilized organic pattern is filled; removing the first solvent-insolubilized-alkaline-solubilized organic pattern and the second solvent-insolubilized-alkaline-solubilized organic pattern using the alkaline developer to obtain an inverted pattern formed of the first insulating material and the second insulating material; and curing the inverted pattern, wherein the first and second acid generators are same or different, the first and second resins are same or different, the first and second acid-labile groups are same or different, the first and second insulating materials are same or different, the first and second polysiloxanes are same or different, and the first and second organic solvents are same or different.
