Abstract
A conductive line is formed in a first insulating layer. A second insulating layer is formed over the conductive line and the first insulating layer. A via extends through the second insulating layer to contact at least the top surface of the conductive line. The via also extends through the first insulating layer to contact at least a top portion of at least one sidewall of the conductive line. The conductive line sidewall may include an outwardly extending hook region, so that a portion of the via is disposed beneath the conductive line hook region, forming a locking region within the via proximate the conductive line hook region.
