Latest Patents

Dong Sub Kwak holds a patent for a method for fabricating a semiconductor device. This method includes several key steps: forming a dielectric layer over a substrate, creating a hole-shaped partial via in the dielectric layer, and forming a line-shaped trench that partially overlaps with the partial via. The trench has a greater line width than the line width of the partial via. Additionally, a hole-shaped via is formed that has a smaller line width than the partial via and penetrates the dielectric layer on a lower surface of the partial via. The process concludes with gap-filling the via, the partial via, and the trench with a conductive material, ensuring that the lower surface of the trench is positioned at a higher level than the lower surface of the partial via.
