A seed layer is formed comprising a metal and an additional constituent that in combination with the metal inhibits nucleation of a fill layer of the metal formed over the seed layer. Tungsten may be doped or alloyed with silicon to form the seed layer, with a tungsten fill being formed over the seed layer.

A method for fabricating an advanced metal conductor structure is described. A pattern in a dielectric layer is provided. The pattern includes a set of features in the dielectric for a set of metal conductor structures. An adhesion promoting layer is created over the patterned dielectric. A ruthenium layer is deposited over the adhesion promoting layer. Using a physical vapor deposition process, a cobalt layer is deposited over the ruthenium layer. A thermal anneal is performed which reflows the cobalt layer to fill the set of features to form a set of metal conductor structures. In another aspect of the invention, an integrated circuit device is formed using the method.

Methods of fabricating semiconductor devices are provided. The method includes forming an interconnect structure over a substrate. The method also includes forming a passivation layer over the interconnect structure.

The lower barrier film and the upper barrier film are made of metal nitride, and the upper barrier film has a nitrogen atomic percentage that is higher than a nitrogen atomic percentage of the lower barrier film and has an amorphous structure.

Embodiments of the disclosed technology include patterning a graphene sheet for biosensor and electronic applications using lithographic patterning techniques. More specifically, the present disclosure is directed towards the method of patterning a graphene sheet with a hard mask metal layer. The hard mask metal layer may include an inert metal, which may protect the graphene sheet from being contaminated or damaged during the patterning process.

Performance of a semiconductor device is improved. In one embodiment, for example, deposition time is increased from 4.6 sec to 6.9 sec. In other words, in one embodiment, thickness of a tantalum nitride film is increased by increasing the deposition time. Specifically, in one embodiment, deposition time is increased such that a tantalum nitride film provided on the bottom of a connection hole to be coupled to a wide interconnection has a thickness within a range from 5 to 10 nm.

Resistance of a FINFET is reduced while performance of an element is prevented from being deteriorated due to an increase in stress, thereby performance of a semiconductor device is improved. When a memory cell formed on an upper side of a first fin and an n transistor formed on an upper side of a second fin are mounted on the same semiconductor substrate, the surface of the first fin having a source/drain region of the memory cell is covered with a silicide layer, and part of a source/drain region of the n transistor is formed of an epitaxial layer covering the surface of the second fin.
