Ultra High Density Integrated Composite Capacitor Design for CMOS
High Capacitance, Low Leakage, Requires Less Chip Area
An ultra-high density two-terminal integrated composite capacitor uses a parallel combination of metal oxide metal (MOM), metal oxide silicon (MOS) and metal insulator metal (MIM) capacitors physically laid over one another. This design both conserves area while providing capacitance density comparable to deep trench capacitors. The MOS capacitor, used in accumulation mode, offers high capacitance and low leakage. Floating the MOS source and drain terminals significantly reduces overall system leakage. This capacitor can be used in general-purpose, mixed-signal blocks as well as regular CMOS processes.

More Effective than Deep Trench Capacitors
Custom-fabricated deep trench capacitors are expensive and not available in regular, mixed-signal fabrication processes. This ultra-dense capacitor offers a more cost effective alternative to such specialized and expensive integrated capacitors while producing comparable capacitance density. In addition, it saves active chip area (8X) in regular CMOS process and reduces leakage wastage by 40 times.
