Title: Doyun Kim - Innovator in Semiconductor and Electronic Device Technologies
Introduction
Doyun Kim is an inventor based in Suwon-si, South Korea. He is known for his innovative contributions to semiconductor devices and electronic technologies. Although he currently holds no granted patents, his work in the field is noteworthy.
Latest Patent Applications
Doyun Kim has filed several patent applications that showcase his expertise. One of his latest applications is for a semiconductor device that includes a gate trench situated between a source region and a drain region on a substrate. This device features a first gate insulating layer that covers the lower surface and sidewall of the gate trench, along with a second insulating layer in contact with the upper region of the sidewall of the first gate insulating layer. The gate electrode in the gate trench consists of a lower buried portion in contact with the first gate insulating layer and an upper buried portion positioned above it. The lower buried portion includes a first conductive layer, while the upper buried portion has a work function adjustment layer and a second conductive layer that contains a transition metal.
Another significant application is for an electronic device that comprises a multilayer flexible printed circuit board. This device includes a first housing with a first printed circuit board and a second housing with a second printed circuit board. A hinge connects the two housings, and the multilayer flexible printed circuit board connects the two printed circuit boards. The multilayer flexible printed circuit board is designed with multiple pattern layers and a bonding layer that bonds portions between at least two of the pattern layers. In the folding area, it features a flexure area and a non-flexure area, with bonding layers formed primarily on the non-flexure area.
Conclusion
Doyun Kim is an emerging inventor whose latest patent applications reflect his innovative approach to semiconductor and electronic device technologies. His contributions may pave the way for future advancements in these fields.
