    摘要: A method of forming pluralities of gate sidewall spacers each plurality comprising different associated gate sidewall spacer widths including providing a first plurality of gate structures; blanket depositing a first dielectric layer over the first plurality of gate structures; blanket depositing a second dielectric layer over the first dielectric layer; etching back through a thickness of the first and second dielectric layers; blanket depositing a first photoresist layer to cover the first plurality and patterning to selectively expose at least a second plurality of gate structures; isotropically etching the at least a second plurality of gate structures for a predetermined time period to selectively etch away a predetermined portion of the first dielectric layer; and, selectively etching away the second dielectric layer to leave gate structures comprising a plurality of associated sidewall spacer widths.

    摘要: A method of forming pluralities of gate sidewall spacers each plurality comprising different associated gate sidewall spacer widths including providing a plurality of gate structures formed overlying a substrate and a plurality of dielectric layers formed substantially conformally overlying the gate structures; exposing a first selected portion of the plurality followed by anisotropically etching through a thickness portion comprising at least the uppermost dielectric layer to form a first sidewall spacer width; exposing a first subsequent selected portion of the plurality followed by etching through at least a thickness portion of the uppermost dielectric layer; and, exposing a second subsequent selected portion of the plurality followed by anisotropically etching through at least a thickness portion of the uppermost dielectric layer to form a subsequent sidewall spacer width.

    摘要: Apparatus for forming a semiconductor structure comprising a first layer on top of a substrate wherein the first layer defines conductive regions such as copper interconnect lines and non-conductive regions such as dielectric materials. The conductive regions are covered by a second layer of a material different than the first layer such as for example nickel and then the structure is heat treated such that the interconnect lines and second metal, such as a copper interconnect line and a nickel second layer, interact with each other to form an alloy layer. The alloy layer has superior qualities for adhering to both the copper interconnect lines and a subsequently deposited dielectric material.
