Title:
METHOD FOR PRODUCING CERAMIC GREEN SHEET WITH CONDUCTIVE PATTERN
Document Type and Number:
WIPO Patent Application WO/2024/004461
Kind Code:
A1
Abstract:
Provided is a method for producing a ceramic green sheet with a conductive pattern, the ceramic green sheet having a highly fine conductive pattern and the occurrence of disconnection therein being suppressed. This method for producing a ceramic green sheet with a conductive pattern involves the following steps in the stated order: a step (transferring step) for preparing a base material with a photosensitive layer, and transferring the photosensitive layer on a ceramic green sheet from above the base material, wherein the photosensitive layer contains (a) conductive particles, (b) non-conductive particles, (c) an alkali-soluble resin, (d) a photosensitizing agent, and (e) a solvent and is provided on the base material, and the content of the solvent (e) is 5.0% by mass or less; a step (exposing step A) for bringing the photosensitive layer into contact with an exposure mask and exposing same; and a step (developing step) for developing the photosensitive layer after exposure to form a conductive pattern.
