    Abstract: A liner material and method of use is disclosed. The method includes depositing a silicon layer into a deep void, such as a via or trench, and physical vapor depositing a cobalt seed layer onto the silicon. A supplemental cobalt layer is electroplated over the seed layer. The structure is then annealed, forming cobalt silicide (CoSix). The layer can be made very thin, facilitating further filling the via with highly conductive metals. Advantageously, the layer is devoid of oxygen and nitrogen, and thus allows low temperature metal reflows in filling the via. The liner material has particular utility in a variety of integrated circuit metallization processes, such as damascene and dual damascene processes.

    Abstract: Some embodiments include methods of forming isolation structures. A semiconductor base may be provided to have a crystalline semiconductor material projection between a pair of openings. SOD material (such as, for example, polysilazane) may be flowed within said openings to fill the openings. After the openings are filled with the SOD material, one or more dopant species may be implanted into the projection to amorphize the crystalline semiconductor material within an upper portion of said projection. The SOD material may then be annealed at a temperature of at least about 400° C. to form isolation structures. Some embodiments include semiconductor constructions that include a semiconductor material base having a projection between a pair of openings. The projection may have an upper region over a lower region, with the upper region being at least 75% amorphous, and with the lower region being entirely crystalline.

    Abstract: Some embodiments include methods of forming charge storage transistor gates and standard FET gates in which common processing is utilized for fabrication of at least some portions of the different types of gates. FET and charge storage transistor gate stacks may be formed. The gate stacks may each include a gate material, an insulative material, and a sacrificial material. The sacrificial material is removed from the FET and charge storage transistor gate stacks. The insulative material of the FET gate stacks is etched through. A conductive material is formed over the FET gate stacks and over the charge storage transistor gate stacks. The conductive material physically contacts the gate material of the FET gate stacks, and is separated from the gate material of the charge storage transistor gate stacks by the insulative material remaining in the charge storage transistor gate stacks. Some embodiments include gate structures.

    Abstract: Various embodiments of the invention described herein reduce contact resistance to a silicon-containing material using a first refractory metal material overlying the silicon-containing material and a second refractory metal material overlying the first refractory metal material. Each refractory metal material is a conductive material containing a refractory metal and an impurity. The first refractory metal material is a metal-rich material, containing a level of its impurity at less than a stoichiometric level. The second refractory metal material has a lower affinity for the impurities than does the first refractory metal material. The second refractory metal material can thus serve as an impurity donor during an anneal or other exposure to heat. This net migration of the impurities to the first refractory metal material limits growth of a metal silicide interface between the first refractory metal material and the underlying silicon-containing material, thereby providing ohmic contact with attendant thermal tolerance.

In one implementation, a method of forming an electrically conductive line includes providing a silicon-comprising layer over a substrate. An electrically conductive layer is formed over the silicon-comprising layer. An MSixNy-comprising layer is formed over the electrically conductive layer, where “x” is from 0 to 3.0, “y” is from 0.5 to 10, and “M” is at least one of Ta, Hf, Mo, and W. An MSiz-comprising layer is formed over the MSixNy-comprising layer, where “z” is from 1 to 3.0. A TiSia-comprising layer is formed over the MSiz-comprising layer, where “a” is from 1 to 3.0. The silicon-comprising layer, the electrically conductive layer, the MSixNy-comprising layer, the MSiz-comprising layer, and the TiSia-comprising layer are patterned into a stack comprising an electrically conductive line. Other aspects and implementations are contemplated.
