Latest Patents

One of his latest patents is titled "Enhanced capacitance trench capacitor." This invention involves an integrated circuit that includes a trench capacitor with a semiconductor region where the material composition varies in quantity. The variation occurs with depth, alternating between at least two different values. For instance, the concentration of a dopant or the weight percentage of a second semiconductor material, such as germanium, can alternate in a semiconductor alloy. The trench capacitor features an undulating capacitor dielectric layer, which is influenced by the undulating interior surface of the trench. This design provides enhanced capacitance and can be utilized in memory cells, such as dynamic random access memory (DRAM) cells.

Another significant patent is the "Method of forming enhanced capacitance trench capacitor." This method outlines a fabrication process for a trench capacitor where the semiconductor region's material composition varies in a similar manner. The etching process is dependent on the material composition, resulting in a trench with an interior surface that undulates in depth. This method also includes forming a trench capacitor with an undulating dielectric layer, contributing to enhanced capacitance for applications in memory cells.
