    摘要: The invention relates to a method of encapsulating conductive lines of semiconductor devices and a structure thereof. An encapsulating protective material, such as TaN, Ta, Ti, TiN, or combinations thereof is disposed over conductive lines of a semiconductor device. The encapsulating protective material protects the conductive lines from harsh etch chemistries when a subsequently deposited material layer is patterned and etched. The encapsulating protective material is conductive and may be left remaining in the completed semiconductor device. The encapsulating material is patterned using a masking material, and processing of the semiconductor device is then continued. The masking material may be left remaining in the structure as part of a subsequently deposited insulating material layer.

    摘要: Methods of patterning a magnetic stack of a magnetic memory cell and structures thereof. At least the top magnetic material layer of a magnetic stack is patterned using a hard mask, and a conformal insulating material is deposited over the patterned top magnetic material layer and hard mask. The conformal insulating material is anisotropically etched to remove the conformal insulating material over vertical sidewalls of at least the patterned top magnetic material layer and the hard mask. The remaining conformal insulating material comprises a sidewall spacer hard mask that is used as a mask to pattern the remaining material layers of the magnetic stack. The sidewall spacer hard mask may be left remaining in the magnetic memory cell structure.

    摘要: A magnetoresistive memory cell includes N magnetoresistive elements conductively connected in series (where N is an integer greater than or equal to two). The magnetoresistive elements, respectively, are positioned between at least two adjacent conductive lines. At least one of the conductive lines is a partially split conductive line having at least one slit portion encompassing an interconnect running therethrough and connected to at least one adjacent magnetoresistive element.

    摘要: A method of forming alignment marks on edge chips in a kerf region of a semiconductor workpiece. The alignment marks are formed in at least one material layer of the semiconductor device. The alignment marks are formed using a separate lithography mask, and may extend into lower layers, including the workpiece, of the semiconductor device. An opaque material layer is deposited, and depressions are formed in the opaque layer over the deep alignment mark trenches. The depressions in the opaque material layer are used to align a lithography process to open the opaque material layer over alignment marks in an underlying metallization layer. The alignment marks in the metallization layer are then used to align the lithography process used to pattern the opaque material layer.

At least the top magnetic material layer of a magnetic stack is patterned using a hard mask, and a conformal insulating material is deposited over the patterned top magnetic material layer and hard mask. The conformal insulating material is anisotropically etched to remove the conformal insulating material from horizontal surfaces of the device, leaving portions of the conformal insulating material over vertical sidewalls of at least the patterned top magnetic material layer and the hard mask. The remaining conformal insulating material comprises a sidewall spacer hard mask that is used as a mask to pattern the remaining material layers of the magnetic stack. The sidewall spacer hard mask may be left remaining in the magnetic memory cell structure.
