Photosensitive conductive paste and conductive body pattern formed thereby

Abstract

The purpose of the present invention is to provide a photosensitive conduction paste which is excellent in both of formability of high-fineness patterns and firing properties at <= 600 DEG C. The photosensitive conduction paste contains (A) silver powders having a low degree of crystallinity, (B) an organic binder, (C) a photopolymerizable monomer, and (D) a photopolymerization initiator, in which the silver powder (A) having the low degree of crystallinity exhibits a value of >= 0.15 DEG at a half peak width of the Ag (111) face peak in X-ray analysis patterns.

Description

technical field [0001] The present invention relates to a photosensitive conductive paste and a conductor pattern formed by using the same. In particular, the present invention relates to a photosensitive conductive paste suitable for a conductor material, wherein the conductor material is formed by sintering a pattern coating film. Manufactured, the formation of the patterned coating film uses a photolithography technique (photolithography technique). Background technique [0002] Conventionally, in plasma display panels (PDPs), CCD sensors, image sensors, and other components, electrodes on alkali-free glass or other various glass substrates have been formed by vapor deposition. [0003] However, this vapor deposition method is to put the electrode member in a vacuum container to form a vacuum coating of gold. Its disadvantages are not only large equipment, high price, but also poor operability, including cumbersome entry and exit of the electrode member, and time required...

[0007] On the other hand, when forming electrodes on a glass substrate, since it is necessary to sinter at a temperature below 620°C where the glass does not deform, it is sintered at a higher temperature (800-900°C), and a ceramic substrate or the like is used to form a conductor.
