IC chip coating material and vacuum fluorescent display device using same
First Claim
1. A vacuum fluorescent display device comprising:
- i) an IC chip,ii) one or more bonding wires, wherein each of the bonding wires is connected to an electrode of the IC chip, andwherein the IC chip and the bonding wires are entirely coated by a coating material layer including first metal oxide particles;
second metal oxide particles ; and
third metal oxide particles formed from a metal alkoxide,wherein the first and the second metal oxide particles include oxide particles of at least one metal selected from the group consisting of Fe, Cr and Mn and a composition of the first metal oxide particles is different from that of the second metal oxide particles,wherein the coating material layer further includes flat particles of a composite oxide, andwherein the composite oxide is mica.

Abstract
An IC chip coating material includes first metal oxide particles; a metal alkoxide; an organic solvent; and second metal oxide particles and/or flat particles of a composite oxide, the second metal oxide particles having a composition identical to or different from that of the first metal oxide particles and also having a mean particle size and/or a shape different from that of the first metal oxide particles. Further, a vacuum fluorescent display device includes an IC chip, wherein the IC chip is at least partially coated by a coating material layer including the first metal oxide particles; a metal forming metal alkoxide; and the second metal oxide particles and/or flat particles of a composite oxide.
