Definitions
- the present invention relates to a method for manufacturing a pattern structure.
- a method in which a thin film is formed on a resist pattern using an atomic layer deposition method (ALD method) and the pattern is formed by removing the resist pattern using a lift-off method (see, for example, Patent Documents 1 to 4). ).
- ALD method atomic layer deposition method
- a resist pattern is formed by applying a resist on a substrate and then exposing and developing the resist.
- JP 2011-40656 A JP 2009-157777 A JP 2007-335727 A JP 2008-547150 A
- atomic layer deposition is an excellent method for producing a gate insulating film of a semiconductor device, its use is increasing in recent years.
- it is difficult to apply the lift-off method it is usual to form a pattern by etching after forming a thin film by an atomic layer deposition method. This is because the material deposited by the atomic layer deposition method also adheres to the side wall of the resist pattern, and the deposited film on the substrate and the deposit on the resist pattern are combined to make it difficult to remove the resist pattern.
- Another reason is that the surface of the resist pattern is covered with a deposited film, and the solvent for stripping the resist pattern does not penetrate so much into the resist pattern.
- the present invention has been made in view of the above circumstances, and provides a method for manufacturing a pattern structure that can form a pattern on a substrate at low temperature and low cost and can easily lift off. Objective.
- a method for manufacturing a pattern structure includes a step of forming a lift-off material on a base material by an ink-jet method, and an atom on the base material and the lift-off material. Forming a functional film by a layer deposition method; and forming a pattern from the functional film on the substrate by removing the lift-off material by a lift-off method.
- low-temperature and low-cost processes such as an inkjet method, an atomic layer deposition method, and a lift-off method are possible, and a pattern can be formed on a substrate at a low temperature and low cost by using a method that facilitates lift-off.
- the lift-off material can be formed at a low temperature and at a low cost as compared with a normal photolithography method, and the lift-off is easy.
- the atomic layer deposition method a functional film can be formed at a lower temperature than in a normal film formation method.
- a pattern can be formed at a lower temperature and at a lower cost than in a normal photolithography method.
- the ink jet method is often used for pattern formation with a lower dimensional accuracy than a normal photolithography method.
- the thickness of the material formed on the substrate is large, and unevenness on the order of microns is easily formed on the material surface. For this reason, it is difficult to combine the atomic layer deposition method requiring high dimensional accuracy and the ink jet method.
- the material formed on the substrate is usually used for some purpose, and the material is not purposely removed using the lift-off method.
- Using a lift-off material formed by the inkjet method facilitates lift-off.
- the reason for this is that, for example, an ink with a large amount of solvent or an ink with a non-uniform solvent can be used as compared with other forming methods, so that the surface shape after film formation can be controlled.
- irregularities can be formed on the surface of the lift-off material.
- lift-off is facilitated even when a deposited film having good film formability covers the surface of the lift-off material by the atomic layer deposition method.
- the lift-off material may be formed by applying an ink containing a resin and a solvent on the substrate and then removing the solvent.
- a heterogeneous solvent or a dispersion solvent can be used.
- the surface shape of the lift-off material can be controlled by adjusting the ink composition according to the type of the lift-off material.
- the solvent may include a first solvent having a first solubility in the resin and a second solvent having a second solubility lower than the first solubility.
- the first solvent may be compatible with the second solvent.
- the solvent may further include a third solvent that is compatible with both the first solvent and the second solvent.
- the solvent contained in the ink includes a first solvent having a first solubility in a resin (for example, an aqueous solvent or an alcohol solvent) and a second solvent having a second solubility lower than the first solubility (for example, an alkylene). Glycols or alkyl ethers).
- the first solvent is compatible with the second solvent.
- the first solvent may dissolve the resin, and the second solvent may not dissolve the resin.
- the first solvent volatilizes first.
- the mixing ratio of the first solvent and the second solvent can be determined according to the type of resin.
- the solvent contained in the ink is a first solvent (for example, water) having a first solubility in a resin and a second solvent (for example, an organic solvent such as toluene) having a second solubility lower than the first solubility.
- Solvent and a third solvent (for example, acetone) that is compatible with both the first solvent and the second solvent.
- the second solvent may not be compatible with the first solvent.
- the first solvent may dissolve the resin and the second solvent may not dissolve the resin.
- the boiling point of the third solvent is lower than the boiling points of the first solvent and the second solvent, the third solvent volatilizes first.
- the mixing ratio of the first solvent, the second solvent, and the third solvent can be determined according to the type of resin.
- Examples of the resin used include polyvinyl acetal, polyvinyl pyrrolidone, vinyl acetate-vinyl pyrrolidone copolymer, and polyacrylamide. Among these, polyvinyl acetal and vinyl acetate-vinyl pyrrolidone copolymer are particularly preferable.
- Examples of the solvent used include water, a water-soluble organic solvent, and an organic solvent that is compatible with the water-soluble organic solvent. Examples thereof include water, alcohol, glycol, polyhydric alcohol, ketones, pyrrolidones, glycol ethers, glycol diethers, alkylene glycols, alkyl ethers, and mixed solvents thereof.
- the lift-off material may be made of non-curing resin.
- the lift-off material can be formed at a low temperature simply by volatilizing the solvent without curing.
- the glass transition temperature (Tg) of the resin is, for example, 100 ° C. or less. In this case, by heating the lift-off material to a temperature equal to or higher than the glass transition temperature (Tg) of the resin, the stress on the surface of the lift-off material is relaxed and the surface shape changes. As a result, lift-off is further facilitated.
- the base material may have a convex portion, and the lift-off material may be formed on the convex portion.
- the lift-off material In order to form a lift-off material on the convex portion by a normal photolithography method, it is necessary to flatten the surface of the resist film formed on the substrate.
- the lift-off material when the lift-off material is formed by the ink jet method, the lift-off material can be selectively formed at a desired location, so that a flattening process like a normal photolithography method is unnecessary, and the cost is low. It is.
- the convex portion extends in a first direction along the surface of the base material, and the lift-off material extends in a second direction that intersects the first direction along the surface of the base material. It may be formed as follows.
