Latest Patents

One of Canzhong He's latest patents involves interdigitated capacitors. The specification describes matched capacitor pairs that employ interconnect metal in an interdigitated form, designed with an area-efficient configuration. Structural variations between capacitors in the capacitor pair are minimized to provide optimum matching. The invention ensures that the plates of each pair occupy a common area on the substrate, compensating for structural anomalies due to process conditions. This design allows a given anomaly to affect both capacitors in the same way. Additionally, two of the capacitor plates are formed of comb structures, with the fingers of the combs interdigitated, while the other plates are formed using one or more plates interleaved between the interdigitated plates.

Another significant patent by Canzhong He is for a metal capacitor stacked with a MOS capacitor to provide increased capacitance density. This on-chip capacitive device comprises a semiconductor substrate, a MOS capacitor formed on the substrate, and a metal interconnect capacitor formed at least in part in a region above the MOS capacitor. The MOS capacitor and the metal interconnect capacitor are connected in parallel to form a single capacitive device, allowing for the combination of their capacitance densities. This innovation achieves significant capacitance density gains without requiring additional processing steps.
