Latest Patents

One of his latest patents is a semiconductor memory device that features a device isolation pattern in a substrate. This design defines first and second active sections that are spaced apart from each other. The center of the first active section is adjacent to the end of the second active section. The device includes a bit line that crosses over the center of the first active section, along with a bit-line contact between the bit line and the first active section. Additionally, there is a first storage node pad located on the end of the second active section, which includes a first pad sidewall and a second pad sidewall. The second pad sidewall is convex in a direction away from the bit-line contact when viewed in plan.

Another notable patent by Ahn is a semiconductor memory device and method of fabricating the same. This device includes a device isolation pattern on a substrate that defines a first active section. It features a first storage node pad on the first active section, a word line extending across the first active section, and a bit line crossing over the word line. A storage node contact is positioned on one side of the bit line and adjacent to the first storage node pad, with an ohmic layer placed between the storage node contact and the first storage node pad. The bottom surface of the ohmic layer is rounded, enhancing the device's performance.
