Latest Patents

One of Jin-Seong Lee's latest patents is a semiconductor memory device that includes a work function adjusting layer in a buried gate line. This invention discloses a semiconductor memory device that features a device isolation layer defining active regions of a substrate. The gate lines are buried in the substrate and extend across these active regions. Each gate line consists of a conductive layer, a liner layer separating the conductive layer from the substrate, and a first work function adjusting layer. This layer includes a first work function adjusting material, which has a work function less than that of the conductive layer and the liner layer.

Another notable patent involves a semiconductor memory device that includes a separation member defining active regions of a substrate. In this design, gate lines intersect the active regions and are buried in a trench formed in the substrate. Each gate line comprises a lower electrode structure and an upper electrode structure. The upper structure includes a source layer that substantially covers the trench's sidewall and incorporates a work-function adjustment element. A conductive layer is placed on the source layer, with a work-function adjustment layer positioned between them, which is made from a different material and is doped with the work-function adjustment element.
