Abstract:
1. A method of forming an interconnect, comprising: forming a first dielectric region over a first level of circuitry; forming a second level of circuitry over the first dielectric region, the second level comprising repeating electrically conductive features; while forming the electrically conductive features, forming at least a portion of an interconnect that extends through the second level of circuitry and electrically connects with the first level of circuitry; all of the electrically conductive features of the second level being laterally outward of the interconnect and not contacting the interconnect, along a cross-section; forming a second dielectric region over the second level of circuitry; and forming a third level of circuitry over the second dielectric region, the third level of circuitry being electrically connected to the first level of circuitry through the interconnect.
