Title: Chung-Ming Chu: Innovator in Common Mode Filters and Capacitors

Introduction

Chung-Ming Chu is a prominent inventor based in Hsinchu, Taiwan. He has made significant contributions to the field of electronics, particularly in the development of common mode filters and capacitors. With a total of 7 patents to his name, his work has had a substantial impact on the industry.

Latest Patents

One of his latest patents is a manufacturing method of common mode filters. This innovative method reveals a structure where a common mode choke layer is disposed over a composite substrate, with a second magnetic material layer coated on its upper surface. The common mode choke layer is produced using a wafer-level electrode leading out method, featuring leading-out terminals on its sides. External electrodes are formed on the sides of the common mode choke layer through partial cutting, sputtering, lithography, and electroplating at the wafer level, corresponding to the leading-out terminals. This design allows for more stable support of the common mode filters, minimizes volume due to inductive coils, and enables mass production, thereby reducing costs and defect rates.

Another notable patent involves a method for fabricating a capacitor. This process includes forming a lower electrode of metal over a substrate, creating a capacitor dielectric film of an oxide dielectric film on the lower electrode, and depositing a metal film on the dielectric film. Following this, thermal processing in a hydrogen-content atmosphere is performed, and the metal film is patterned to form an upper electrode. This method enhances the adhesion between the upper electrode and the capacitor dielectric film, improving capacitor characteristics.
