She has made significant contributions to the field of semiconductor memory devices, holding three patents that showcase her innovative approach to technology. Her work focuses on enhancing the reliability and miniaturization of DRAM devices.
Latest Patents
One of her latest patents is for a semiconductor memory device that features a unique structure in which a storage node electrode is formed via an insulator film in a trench within a memory cell region. This design allows for the formation of a capacitor while ensuring that the storage node electrode connects to the source/drain regions of a MOSFET through a storage node contact. The trench is strategically placed to minimize the distance between adjacent element regions without causing misalignment during the mask formation process. This innovation leads to a miniaturized, high-reliability DRAM.
Another notable patent describes a method of fabricating a semiconductor memory device. This method includes a first contact hole made in a first inter-layer insulating film over a gate electrode and a second contact hole in a second inter-layer insulating film. The design allows for a smaller memory device while improving reliability. The capacitor is formed in a layer above the bit line, facilitating the processing of the storage node electrode and enhancing the capacitor area.
