Title: Il-Kweon Joung: Innovator in Semiconductor Technology
Introduction
Il-Kweon Joung is a prominent inventor based in Seongnam-si, South Korea. He has made significant contributions to the field of semiconductor technology, holding a total of 5 patents. His work focuses on enhancing the efficiency and functionality of electronic components, particularly in light-emitting devices and tactile sensors.
Latest Patents
One of Joung's latest patents is for a semiconductor light-emitting diode (LED). This invention discloses a method for manufacturing a semiconductor LED that includes forming a light-emitting structure composed of an N-type semiconductor layer, an active layer, and a P-type semiconductor layer stacked together on a substrate. The method also involves processing a division groove in the shape of a dotted line and dividing the substrate and the light-emitting structure along this groove. This innovative approach can prevent total reflection of light emitted through the sides, thereby improving light-emitting efficiency.
Another notable patent is for a tactile sensor. This device includes a circuit board, multiple unit electrode pads, and a pressure-sensing film. The circuit board features a first circuit pattern that connects unit electrode pads in the same column, a second pattern for those in the same row, and a third pattern for pads in the same section. This design allows for enhanced pressure sensing capabilities in a two-dimensional configuration.
