초록

Integrated passive device (IPD) technology has emerged with the need for 5G. In order to integrate and miniaturize capacitors inside IPD, various studies are actively performed using high-k materials and trench structures. In this paper, an EM(Electromagnetic) simulation study was performed by applying an oxide dielectric to the capacitors having a various trench type structures. Commercially available materials HfO2, Al2O3, and Ta2O5 are applied to non, circle, trefoil, and quatrefoil type trench structures to confirm changes in each material or structure. As a result, the bigger the capacitor area and the higher dielectric constant of the oxide dielectric, the insertion loss tended to decrease.
