Title:
METHOD FOR MANUFACTURING ELEMENT CHIP
Document Type and Number:
Japanese Patent JP2018056178
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method for manufacturing an element chip forming a resist pattern on a substrate held by a holding tape and, subsequently, etching the substrate with plasma.SOLUTION: A method for manufacturing an element chip includes: a step of preparing a substrate having a first surface and a second surface opposite to the first surface and having a plurality of element regions and division regions defining the element regions, with the second surface held by a holding tape; a step of producing particles by spraying resist solution containing a resist component and a solvent; a step of forming a resist film by volatilizing the solvent from the particles and, subsequently, depositing the resist component on the first surface of the substrate held by the holding tape; a patterning step of patterning the resist film and exposing the division regions on the first surface of the substrate; and a step of etching the division regions from the first surface with plasma.SELECTED DRAWING: Figure 3
