摘要： A method for forming a sacrificial planarization layer over an SOG layer which provide a more planar final surface. A substrate is provided with a first insulating layer formed on its surface. A spin-on-glass (SOG) layer is formed over the first insulating layer. The SOG layer has a greater thickness towards the outer edge compared to the central area of the substrate. Next a sacrificial layer is formed over the SOG layer. The sacrificial layer, preferably formed of silicon oxide material, is formed so that the layer has a greater thickness towards the outside of the wafer than in the central area. Next, the sacrificial layer is etched away and portions of the SOG layer are etched. The etch rates of the sacrificial layer, the SOG layer and the first insulating layer are approximately equal so that the planar top SOG surface is transferred to the final top surface after the etch. The resulting surface is planar because the additional sacrificial layer thickness in the outside periphery compensated for the thinner SOG in on the periphery and the faster etch rate on the periphery.

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 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 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.

摘要： A process for creating BPSG filled, shallow trench isolation regions, in a semiconductor substrate, has been developed. The process features the use of a BPSG layer with about 4 to 4.5 weight percent B.sub.2 O.sub.3, and about 4 to 4.5 weight percent P.sub.2 O.sub.5, in silicon oxide. This BPSG composition, when subjected to a high temperature anneal procedure, results in softening, or reflowing, of the BPSG layer, eliminating seams or voids, in the BPSG layer, that may have been present after BPSG deposition. The removal rate of BPSG, is lower than the removal rate of silicon oxide layer, in buffered HF solutions, thus allowing several buffered HF procedures to be performed without recessing of BPSG in the shallow trench. In addition this composition of BPSG performs as a gettering material for mobile ions, thus contributing to yield and reliability improvements, when used at the isolation region for MOSFET devices.

摘要翻译： 已经开发了用于在半导体衬底中产生BPSG填充的浅沟槽隔离区的工艺。 该方法的特征在于在氧化硅中使用具有约4至4.5重量％的B 2 O 3和约4至4.5重量％的P 2 O 5的BPSG层。 当经过高温退火过程时，该BPSG组合物导致BPSG层的软化或回流，消除了在BPSG沉积后可能存在的BPSG层中的接缝或空隙。 BPSG的去除率低于缓冲HF溶液中氧化硅层的去除率，从而允许在浅沟槽中不进行BPSG的凹陷而执行几个缓冲的HF程序。 此外，BPSG的这种组合作为移动离子的吸气材料，当在MOSFET器件的隔离区域使用时，有助于提高产量和可靠性。
