| 20090128993 | MULTI-TIER CAPACITOR STRUCTURE, FABRICATION METHOD THEREOF AND SEMICONDUCTOR SUBSTRATE EMPLOYING THE SAME - A multi-tier capacitor structure has at least one multi-tier conductive layer. At least one conductive via passes through the multi-tier conductive layer. When currents flow through the conductive via, different current paths are presented in the conductive via in response to different current frequency; in other words, different inductor is induced. Therefore, a single plate capacitor structure has function of hierarchical decoupling capacitor effect. | 05-21-2009 |
