摘要:
A method for reducing leakage current in a semiconductor capacitor. The method includes providing a top plate for collecting charge, providing a bottom plate for collecting an opposing charge to the top plate, providing a dielectric layer for insulation between the top plate and the bottom plate, providing a top contact, providing a bottom contact, providing a plurality of vias including top level vias for connecting the top plate to the top contact, and bottom level vias for connecting the bottom plate to the bottom contact; and separating a via and an adjacent structure such that their distance is greater than a minimum via spacing requirement of a foundry design rule for a semiconductor process producing the semiconductor capacitor.
