Title:
MANUFACTURING METHOD OF ION CRYSTAL PATTERN AND LIGHT-EMITTING ELEMENT
Document Type and Number:
Japanese Patent JP2022184258
Kind Code:
A
Abstract:
To prevent an ion crystal layer from being exfoliated together with a sacrificial layer in patterning of the ion crystal layer using the sacrificial layer.SOLUTION: A manufacturing method of an ion crystal pattern includes steps of: forming a lower layer having a surface; forming an organic compound pattern containing an organic compound on a first region included in the surface; forming a precursor solution layer by coating the organic compound pattern and a second region included in the surface with a precursor solution containing a first solvent and a precursor of an ion crystal dispersed in the first solvent; forming an ion crystal layer comprising a first portion disposed in contact on the organic compound pattern and a second portion disposed in contact on the second region and containing the ion crystal by vaporizing the first solvent from the precursor solution layer; and removing the first portion by dissolving the organic compound pattern in a second solvent having a lower polarity than that of the first solvent.SELECTED DRAWING: Figure 4
