Pattern decomposition lithography techniques

Techniques are disclosed for realizing a two-dimensional target lithography feature/pattern by decomposing (splitting) it into multiple unidirectional target features that, when aggregated, substantially (e.g., fully) represent the original target feature without leaving an unrepresented remainder (e.g., a whole-number quantity of unidirectional target features). The unidirectional target features may he arbitrarily grouped such that, within a grouping, all unidirectional target features share a common target width value. Where multiple such groupings are provided, individual groupings may or may not have the same common target width value. In some cases, a series of reticles is provided, each reticle having a mask pattern correlating to a grouping of unidirectional target features. Exposure of a photoresist material via the aggregated series of reticles substantially (e.g., fully) produces the original target feature/pattern. The pattern decomposition techniques may be integrated into any number of patterning processes, such as litho-freeze-litho-etch and litho-etch-litho-etch patterning processes.

HYBRID BOND USING A COPPER ALLOY FOR YIELD IMPROVEMENT

An integrated circuit (IC) using a copper-alloy based hybrid bond is provided. The IC comprises a pair of semiconductor structures vertically stacked upon one another. The pair of semiconductor structures comprise corresponding dielectric layers and corresponding metal features arranged in the dielectric layers. The metal features comprise a copper alloy having copper and a secondary metal. The IC further comprises a hybrid bond arranged at an interface between the semiconductor structures. The hybrid bond comprises a first bond bonding the dielectric layers together and a second bond bonding the metal features together. The second bond comprises voids arranged between copper grains of the metal features and filled by the secondary metal. A method for bonding a pair of semiconductor structures together using the copper-alloy based hybrid bond is also provided.
