    摘要: A method forming a protective (SiON or PE-Ox) dielectric anti-reflective coating (DARC) over a dielectric layer after a chemical-mechanical polish dielectric layer planarization process and before a chemical-mechanical polish of a conductive layer used in a contact or via plug formation. A dielectric layer is chemical-mechanical polished thereby creating microscratches in the dielectric layer. The invention's protective SiON or PE-OX DARC layer is formed over the dielectric layer whereby the protective SiON or PE-OX DARC layer fills in the microscratches. A first opening is etched in he protective layer and the dielectric layer. A conductive layer is formed over the protective layer and fills the first opening. The conductive layer is chemical-mechanical polished to remove the conductive layer from over the protective layer and to form an interconnect filling the first opening. The protective SiON or PE-OX DARC layer is used as a CMP stop thereby preventing microscratches in the dielectric layer.

    摘要: A method is disclosed for forming alignment marks at the outer perimeter of wafers where they are not susceptible to much damage during chemical-mechanical polishing (CMP) process. Complete protection is provided by recessing the alignment mark into the substrate by etching. Recess etching is accomplished at the same time the isolation trenches are followed to delineate device areas. Thus, alignment marks are provided with a protective recess without extra steps. Furthermore, by forming alignment marks at the outer perimeter of the wafer, productivity is improved by providing maximum usage of wafer area for integrated circuits.

    摘要: The process of polishing the top surface of a polysilicon gate electrode often results in significant loss of material before adequate smoothness is achieved. This problem is overcome in the present invention by laying down a thin layer of a dielectric on the surface of the polysilicon prior to the application of CMP. This provides a sacrificial layer that facilitates the polishing operation and results in a polysilicon surface that is both very smooth and achievable with minimum loss of polysilicon.

    摘要: A method for forming a silicon oxide dielectric layer within a microelectronics fabrication. There is first provided a silicon substrate layer employed within a microelectronics fabrication. There is then formed employing the silicon substrate a thermal silicon oxide layer through thermal oxidation of the silicon substrate layer. There is then formed upon the thermal silicon oxide layer a second silicon oxide layer formed through use of a thermal chemical vapor deposition (CVD) method employing ozone as an oxidant and tetraethylorthosilicate (TEOS) as a silicon source material. The thermal chemical vapor deposition (CVD) method also employs a reactor chamber pressure of from about 40 to about 80 torr. The second silicon oxide layer is formed with an attenuated surface sensitivity of the second silicon oxide layer with respect to the thermal silicon oxide layer. The method is particularly desirable when forming trench isolation regions within isolation trenches within silicon semiconductor substrates employed within integrated circuit microelectronics fabrications.
