Monolithic capacitor is another name for the monolithic construction. The internal electrodes are layered one after the other to increase the area of the capacitor's two electrode plates, hence increasing the capacitance. The internal filling material is ceramic dielectric.
In conclusion, monolithic 3D capacitors designed for operating at high voltages of 100 V (equivalent oxide field of 6 MV/cm) were successfully fabricated based on the TSV technology. To achieve high-breakdown voltages, a hybrid dielectric stack of SiO 2 /Si 3 N 4 was formed on a highly doped Si-substrate.
The domain of monolithic ceramic capacitors is gradually being expanded by the rapid enhancement of capacitance. Meanwhile, aluminum and tantalum electrolytic capacitors are also barely managing to hold their own against the growth of monolithic ceramic capacitors as a result of improvements in withstand voltage and capacitance.
Another advantage is that they are highly resistant to abnormal voltage. When comparing products with a rated voltage of 16 V and a capacitance of 10 μF, for example, the DC breakdown voltage of an aluminum electrolytic capacitor is only 30 V and that of a tantalum electrolytic capacitor is 30-60 V.
In contrast, a multilayer ceramic capacitor has an extremely high DC breakdown voltage (approximately 200 V). Thus, if a multilayer ceramic capacitor is mounted in an electronic device, the risk of failure due to dielectric breakdown can be minimized, even when a surge or pulse voltage is generated in the device for some reason.
