Title: Kimyoung Yun and Multilayer Ceramic Capacitor Innovations.

Introduction

Kimyoung Yun is an inventor based in Suwon, South Korea, whose patent work focuses on multilayer ceramic capacitors and the materials and structures used to improve their dielectric layers. He is associated with Samsung Electro-Mechanics and has 3 patents.

Latest Patents

One of Yun’s latest patents, “Multilayer Ceramic Capacitor Including Silicon, Dysprosium, and Terbium, and Manufacturing Method of the Multilayer Ceramic Capacitor,” describes a capacitor with a dielectric layer made of grains and the boundaries between them. The dielectric grains include a barium titanate-based main component, while the grain boundaries contain silicon, dysprosium, and terbium in a specified relative content order: terbium, dysprosium, then silicon. The invention also covers a method for manufacturing the capacitor.

Another patent, “Multilayer Capacitor Having a Dielectric Layer with Core-Shell Structured Dielectric Grains,” describes dielectric grains with a core, a shell, and an intervening core-shell wall. It also specifies a relationship between the average concentration of a minor component in the grain boundary and its concentration in the core-shell wall, with the ratio falling within a defined range. This material design is intended to control the composition of the dielectric layer.

Career Highlights

Yun’s disclosed patent work centers on multilayer ceramic capacitor design, particularly dielectric grain composition, grain-boundary chemistry, and core-shell structures. These approaches address how material distribution within a capacitor’s dielectric layer can be specified and engineered.
