Abstract

This invention is a paste composition containing an inorganic filler, a resin and a solvent, wherein the paste composition is characterized in that it contains one or more solvents of which boiling point is 160 DEG C or higher and an inorganic filler of which mean particle diameter is 5 m or smaller, and the total content of the solvent being 25 wt% or less based on the total amount of the paste composition, and relates to a dielectric composition containing an inorganic filler and resin, wherein the inorganic filler includes inorganic fillers of at least two kinds of mean particle diameter, and the greatest mean particle diameter of said mean particle diameters is 0.1-5 m and is 3 times or more to the minimum mean particle diameter. By this invention, it is possible to obtain a high dielectric constant composition of which linear expansion coefficient is low, and which has a large capacitance.

Description

[0001] This application is a divisional application of the patent application with the application number 200480009120.2, the filing date is March 25, 2004, and the invention title is "paste composition and dielectric composition using the paste composition". technical field

[0002] The present invention relates to a dielectric composition exhibiting excellent characteristics as an interlayer insulating material or an optical wiring material for a capacitor or a circuit material having a capacitor function. Background technique

[0003] In recent years, along with the miniaturization of electronic equipment, the increase in the speed of signals, and the increase in capacity, the density of mounted circuit components has been increasing. However, problems such as an increase in electrical noise and generation of data errors also arise. In order to suppress the generation of this electrical noise and operate the semiconductor device stably, it is important to supply a necessa...
