  • Patent number: 8497194
    Abstract: Some embodiments include methods of forming one or more doped regions in a semiconductor substrate. Plasma doping may be used to form a first dopant to a first depth within the substrate. The first dopant may then be impacted with a second dopant to knock the first dopant to a second depth within the substrate. In some embodiments the first dopant is p-type (such as boron) and the second dopant is neutral type (such as germanium). In some embodiments the second dopant is heavier than the first dopant.

  • Patent number: 8435889
    Abstract: The invention included to methods of forming CoSi2, methods of forming field effect transistors, and methods of forming conductive contacts. In one implementation, a method of forming CoSi2 includes forming a substantially amorphous layer comprising MSix over a silicon-containing substrate, where “M” comprises at least some metal other than cobalt. A layer comprising cobalt is deposited over the substantially amorphous MSix-comprising layer. The substrate is annealed effective to diffuse cobalt of the cobalt-comprising layer through the substantially amorphous MSix-comprising layer and combine with silicon of the silicon-containing substrate to form CoSi2 beneath the substantially amorphous MSix-comprising layer. Other aspects and implementations are contemplated.

  • Publication number: 20130012013
    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.

  • Publication number: 20120329231
    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.
