SUPERFINE COPPER POWDER SLURRY AND PROCESS FOR PRODUCING THE SAME

摘要

a Ultrafine dongbun ( ) slurry , when used in wiring conductive ink or conductive paste , than fine and that to form parts of a wiring pitches on the substrate in order . In order to achieve this purpose , D _TEM ( ) is 0.01 ~ 0.1, D ₅₀ / D _TEM is 1.0 to 1.5 , and crystal particle size / D _TEM : 0.2 ~ 1 second with the powder properties of the particulate matter suspended in the solvent dongbun provides ultrafine dongbun prepared slurry (D _TEM is a TEM measuring the particle size of the powder directly to the art from the photo on the observation point to the average primary particle diameter in terms of observation magnification , D ₅₀ refers to the volume cumulative particle size of 50% , measured according to the Doppler scattering light analysis .).
