Latest Patent Applications

One of his notable patent applications is for an image sensor that includes a pixel array with a plurality of photodiodes arranged on a substrate's upper surface. This design features pixel isolation layers that extend from the upper surface to the lower surface of the substrate, positioned between the photodiodes. The pixel array consists of pixel groups that include multiple photodiodes, at least one color filter, and at least one microlens. Each color filter in the pixel groups has a single color, while the pixel isolation layers comprise a first layer containing silicon oxide and polysilicon, and a second layer that extends in two intersecting directions between the photodiodes.

Another significant application is for a semiconductor device and electronic system that includes a stacked structure of gate electrodes and interlayer insulating layers. This device features a channel structure that penetrates the stacked structure, with a first pad portion overlapping a control gate electrode. The design ensures that the largest width of the first pad portion exceeds the smallest width of the channel portion, enhancing the device's functionality.

Conclusion

Sanghoon Kim's innovative work in image sensor technology and semiconductor devices showcases his potential as an inventor. His latest patent applications reflect a commitment to advancing technology in these fields.
