Introduction

Kang-Soo Chu is a notable inventor based in Yongni-si, South Korea. He has made significant contributions to the field of semiconductor devices and inkjet print heads. With a total of 2 patents, his work has had a considerable impact on technology and manufacturing processes.

Latest Patents

Kang-Soo Chu's latest patents include a method of fabricating a semiconductor device having multiple gate dielectric layers. This method involves forming an isolation layer that defines first and second active regions in a semiconductor substrate. A passivation layer is then formed on the substrate, followed by a first patterning process that etches the passivation layer to expose the first active region. A first dielectric layer is formed in this exposed region. Similarly, a second patterning process is carried out for the second active region, leading to the formation of a second dielectric layer.

Another significant patent is for an inkjet print head and the method of fabricating it. This inkjet print head features a substrate with an ink-feed hole, surrounded by an interlayer dielectric layer. It includes at least one metal layer and an anti-moisture part designed to prevent ink moisture from contacting the metal layer. This innovation addresses issues such as de-lamination, electrical short-circuits, and corrosion, thereby enhancing the lifespan and reliability of the inkjet print head while also improving productivity and reducing manufacturing costs.
