Vertical parallel plate capacitor structures

摘要

Vertical parallel plate (VPP) capacitor structures that utilize different spacings between conductive plates in different levels of the capacitor stack. The non-even spacings of the conductive plates in the capacitor stack decrease the susceptibility of the capacitor stack of the VPP capacitor to ESD-promoted failures. The non-even spacings may be material specific in that, for example, the spacings between adjacent conductive plates in different levels of the capacitor stack may be chosen based upon material failure mechanisms for plates containing different materials.
