Latest Patents

One of Han-Sin Lee's latest patents is for a resistive random access memory device. This device includes a first electrode, a resistive oxidation structure, and a second electrode. The resistive oxidation structure consists of sets of oxidation layers stacked on the first electrode. Each set is composed of a first metal oxide layer and a second metal oxide layer, with the latter being thinner than the former. The first metal oxidation layer of the first set contacts the upper surface of the first electrode, while the second electrode is formed on the resistive oxidation structure. The resistance of the oxidation structure can be altered by an electric field.

Another notable patent is for a multi-level semiconductor device and its fabrication method. This device features a first transistor on a semiconductor substrate, which includes a first source/drain region. A semiconductor layer is placed on the substrate, with a second transistor positioned on this layer. The second transistor has a second source/drain region located in a specific portion of the semiconductor layer, and a contact pattern extends from the first source/drain region to another portion of the semiconductor layer, which has a higher impurity concentration than the second source/drain region.
