摘要:
An interconnect structure that includes a dielectric material having a dielectric constant of about 3.0 or less is provided. This low k dielectric material has at least one conductive material having an upper surface embedded therein. The dielectric material also has a surface layer that is made hydrophobic prior to the formation of the noble metal cap. The noble metal cap is located directly on the upper surface of the at least one conductive material. Because of the presence of the hydrophobic surface layer on the dielectric material, the noble metal cap does not substantially extend onto the hydrophobic surface layer of the dielectric material that is adjacent to the at least one conductive material and no metal residues from the noble metal cap deposition form on this hydrophobic dielectric surface.

Voltage programmable anti-fuse structures and methods are provided that include at least one conductive material island atop a dielectric surface that is located between two adjacent conductive features. In one embodiment, the anti-fuse structure includes a dielectric material having at least two adjacent conductive features embedded therein. At least one conductive material island is located on an upper surface of the dielectric material that is located between the at least two adjacent conductive features. A dielectric capping layer is located on exposed surfaces of the dielectric material, the at least one conductive material island and the at least two adjacent conductive features. When the anti-fuse structure is in a programmed state, a dielectric breakdown path is present in the dielectric material that is located beneath the at least one conductive material island which conducts electrical current to electrically couple the two adjacent conductive features.

摘要:
A hard mask is formed on an interconnect structure comprising a low-k material layer and a metal feature embedded therein. A block polymer is applied to the hard mask layer, self-assembled, and patterned to form a polymeric matrix of a polymeric block component and containing cylindrical holes. The hard mask and the low-k material layer therebelow are etched to form cavities. A conductive material is plated on exposed metallic surfaces including portions of top surfaces of the metal feature to form metal pads. Metal silicide pads are formed by exposure of the metal pads to a silicon containing gas. An etch is performed to enlarge and merge the cavities in the low-k material layer. The metal feature is protected from the etch by the metal silicide pads. An interconnect structure having an air gap and free of defects to surfaces of the metal feature is formed.

An anti-fuse structure that included a buried electrically conductive, e.g., metallic layer as an anti-fuse material as well as a method of forming such an anti-fuse structure are provided. According to the present invention, the inventive anti-fuse structure comprises regions of leaky dielectric between interconnects. The resistance between these original interconnects starts decreasing when two adjacent interconnects are biased and causes a time-dependent dielectric breakdown, TDDB, phenomenon to occur. Decreasing of the resistance between adjacent interconnects can also be expedited via increasing the local temperature.

A modularized capacitor array includes a plurality of capacitor modules. Each capacitor module includes a capacitor and a switching device that is configured to electrically disconnect the capacitor. The switching device includes a sensing unit configured to detect the level of leakage of the capacitor so that the switching device disconnects the capacitor electrically if the leakage current exceeds a predetermined level. Each capacitor module can include a single capacitor plate, two capacitor plates, or more than two capacitor plates. The leakage sensors and switching devices are employed to electrically disconnect any capacitor module of the capacitor array that becomes leaky, thereby protecting the capacitor array from excessive electrical leakage.
