Latest Patents

One of Miyamoto's latest patents involves a unique capacitor designed for semiconductor integrated circuits. This invention features a ferroelectric thin film that is strategically placed after a MOS transistor is formed on a substrate. The ferroelectric materials, such as PbZrTiO.sub.3 or SrTiO.sub.3, are formed into a columnar shape, allowing electrodes to come into direct contact with the side walls of the ferroelectric thin film. This design averts the formation of oxides at the electrode interface that can reduce relative permittivity, thereby facilitating a large capacitance relative to the substrate area. The advancement aims to create memory cells for DRAM or FRAM that offer high integration degrees and processing speeds.

Another patent by Miyamoto also details a capacitor construction in semiconductor integrated circuits similar to his first patent, emphasizing the benefits of the columnar ferroelectric thin film structure. This innovation secures enhanced capacitor efficiency and memory performance, which are critical in modern electronic devices.
