Method of producing ceramic green sheet and electronic component

Abstract

A laminated ceramic electronic component, wherein a ceramic green sheet used for forming this has an internal electrode and is flat. Specifically, a ceramic green sheet is obtained by forming electrode parts on the surface of a transparent substrate, spreading thereover photosensitive slurry having dielectric powder, exposing this photosensitive slurry up to a specified thickness from the rear surface of the substrate and then developing this, and later removing the substrate.

Description

technical field [0001] The present invention relates to a method of manufacturing an electronic device, particularly a so-called multilayer ceramic formed by laminating ceramics, and a method of manufacturing a so-called ceramic green sheet used therein. In addition, as the multilayer ceramic electronic components described here, multilayer ceramic capacitors, multilayer ceramic inductors, and LC composite components incorporating them or EMC-related components will be described as specific examples. Background technique [0002] In recent years, with the miniaturization and rapid spread of electronic equipment such as mobile phones, people are also seeking to achieve higher density mounting and high performance of electronic components used in them. In particular, multilayer ceramic electronic components used as passive devices are required to be thinner, multilayered, and uniform in each layer in order to meet such requirements, and research is being conducted on manufactu...

Problems solved by technology

[0012] Therefore, when screen printing is performed to embed the conductive paste in the concave portion, the concave portion may be deformed, causing problems in the formation accuracy and formation position of the concave portion.

Therefore, in fact, it is difficult to make the formation accuracy of the concave portion and the electrode formation accuracy by screen printing consistent, and due to the difference in their positional accuracy or the positional deviation when each is formed, there may be a difference in height or height on the substrate. gap

Furthermore, the existence of the convex portion promotes the occurrence of the difference in molding density during lamination pressurization as described in Patent Document 2.

Therefore, it is considered that even if the occurrence of the difference in height is suppressed to some extent, the above-mentioned unevenness in the electrical characteristics will still occur.
