METHOD OF FORMING PATTERN ON CERAMIC GREEN SHEET AND CONDUCTIVE PASTE FOR USE IN THE METHOD

Document Type and Number:

WIPO Patent Application WO/2004/008818

Kind Code:

A1

Abstract:

A technique of forming a pattern on a ceramic green sheet that attains cost reduction and is excellent in productivity. This forming technique is characterized by filling, without the use of a mask, the via holes of a ceramic green sheet having via holes with alkali soluble conductive paste (a), the alkali soluble conductive paste (a) comprising a binder soluble in an alkali aqueous solution and conductive particles as main components, subsequently applying alkali soluble photosensitive conductive paste (b) for wiring pattern onto the ceramic green sheet, and thereafter subjecting the same to drying, pattern exposure and development.
