Title: The Innovations of Jong-bong Ha

Introduction

Jong-bong Ha is a prominent inventor based in Yongin-si, South Korea. He has made significant contributions to the field of electronics, particularly in the development of high electron mobility transistors (HEMTs). With a total of 17 patents to his name, Ha's work has had a considerable impact on the industry.

Latest Patents

One of his latest patents is focused on a high electron mobility transistor and the method of manufacturing it. According to the patent, the HEMT includes a stack comprising a buffer layer, a channel layer containing a two-dimensional electron gas (2DEG) channel, and a channel supply layer. This stack defines a first hole and a second hole that are spaced apart from each other. The design features a first electrode, a second electrode, and a third electrode that are also spaced apart along the first surface of the channel supply layer. Additionally, a first pad is positioned on the buffer layer and extends through the first hole of the stack to the first electrode, while a second pad extends through the second hole to the second electrode. A third pad is located under the stack and is electrically connected to the third electrode.

Another notable patent by Ha also pertains to a high electron mobility transistor. This invention includes a channel supply layer that induces a two-dimensional electron gas (2DEG) in a channel layer. It features a source electrode and a drain electrode positioned at the sides of the channel supply layer, along with a depletion-forming layer that contacts the source electrode. A gate insulating layer is placed on the depletion-forming layer, topped by a gate electrode. The depletion-forming layer is crucial as it forms a depletion region in the 2DEG.
