Latest Patents

One of Hag-ju Cho's latest patents is a method of fabricating a semiconductor device having a dual gate. This innovative method allows for the gates to have a wide variety of threshold voltages. The process includes forming a gate insulation layer, a first capping layer, and a barrier layer across a first region and a second region on a substrate. The method further involves exposing the gate insulation layer on the first region by removing the first capping layer and the barrier layer, forming a second capping layer on the gate insulation layer in the first region and on the barrier layer in the second region, and thermally processing the substrate. This thermal processing enables the material of the second capping layer to spread into the gate insulation layer in the first region, while the material of the first capping layer spreads into the gate insulation layer in the second region. Consequently, devices with different threshold voltages can be formed in the first and second regions.
