Dielectric composite oxide with specific composition for electroneutrality
The patent application (Publication Number: US20240038411A1) discloses a dielectric material for capacitors, comprising a composite oxide with the composition represented by CexAl1-xOk, where x falls within the range of 0.400 to less than 0.900 to maintain electroneutrality. The dielectric can be in the form of a sputtered film and is specifically designed for use in capacitors.
Furthermore, the patent application describes a capacitor structure incorporating the aforementioned dielectric material. The capacitor includes a first electrode, the dielectric layer, and a second electrode covering part of the dielectric. The first electrode may have a porous portion and be made of a valve metal such as aluminum, tantalum, or niobium. The second electrode can be composed of various materials like aluminum, tantalum, or gold. Additionally, the capacitor may contain an electrolyte solution or conductive polymer in contact with the second electrode. The patent also extends to applications of the capacitor in electrical circuits, circuit boards, and various apparatuses.
