    摘要: An improved magnetoresistive memory device has a reduced distance between the magnetic memory element and a conductive memory line used for writing to the magnetic memory element. The reduced distance is facilitated by forming the improved magnetoresistive memory device according to a method that includes forming a mask over the magnetoresistive memory element and forming an insulating layer over the mask layer, then removing portions of the insulating layer using a planarization process. A conductive via can then be formed in the mask layer, for example using a damascene process. The conductive memory line can then be formed over the mask layer and conductive via.

    摘要: A method is provided for fabrication of a semiconductor substrate having regions isolated from each other by shallow trench isolation (STI) structures protruding above a surface of the substrate by a step height. The method includes the steps of forming a bottom antireflective coating (BARC) layer overlying the surface of a semiconductor substrate and the surface of STI structures; etching back a portion of the BARC layer overlying at least one of the STI structures, and partially etching back the at least one of the STI structures, to reduce the step height by which the STI structure protrudes above the surface of the substrate; and removing a remaining portion of the BARC layer between adjacent STI structures. The method may be used to fabricate semiconductor devices including memory cells that have improved reliability.

    摘要: The invention provides a method for etching silicon nitride selective to titanium silicide and fabricating multi-level contact openings on a quartermicron device using a two step etch process. The process begins by providing a substrate having thereover a silicon nitride hard mask at one level and a titanium silicide layer at another level wherein the silicon nitride hard mask and the titanium silicide region have an oxide layer thereover. In a first etch step, the oxide layer is patterned to form a first contact opening and a second contact opening. The first contact opening stops on the silicon nitride hard mask and the second contact opening stops on the titanium silicide region. In a second etch step the silicon nitride hard mask is etched through in the first contact opening using an etch selective to titanium silicide. The etch comprises CH2F2 and O2 at a ratio of CH2F2 to O2 of between about 2 and 4.
