    • A method for seamless gap filling is provided, including providing a semiconductor structure with a device layer having a gap therein, wherein the gap has an aspect ratio greater than 4. A liner layer is formed over the device layer exposed by the gap. A first un-doped oxide layer is formed over the liner layer in the gap. A doped oxide layer is formed over the first undoped oxide layer in the gap. A second un-doped oxide layer is formed over the doped oxide layer in the gap to fill the gap. An annealing process is performed on the second un-doped oxide layer, the doped oxide layer, and the first un-doped oxide to form a seamless oxide layer in the gap, wherein the seamless oxide layer has an interior doped region.

    • Multiple oxide layers with different thicknesses are formed on a semiconductor substrate with a silicon surface, having a first and second region. A sacrificial oxide layer is formed on the silicon surface to cover both the first region and the second region, with a mask layer formed on the surface of the sacrificial oxide layer. By defining and patterning the mask layer, a first opening and a second opening, having predetermined surface areas, are formed in portions of the first and second regions of the mask layer to expose portions of the. The sacrificial oxide layer has a surface area equal to the first predetermined surface area, and portions of the sacrificial oxide layer having a surface area equal to the second predetermined surface area. A linear nitrogen doping process is then performed to simultaneously implant nitrogen ions with a first and second predetermined concentration into the first and second region, through the first opening and the second opening, respectively. Thereafter, the mask layer and the sacrificial oxide layer are removed, respectively. An oxidation process is performed to two silicon oxide layers with different thicknesses in the first and second regions.
    • 在具有第一和第二区域的具有硅表面的半导体衬底上形成具有不同厚度的多个氧化物层。 牺牲氧化物层形成在硅表面上,以覆盖第一区域和第二区域,掩模层形成在牺牲氧化物层的表面上。 通过限定和图案化掩模层,具有预定表面积的第一开口和第二开口形成在掩模层的第一和第二区域的一部分中,以暴露部分。 牺牲氧化物层的表面积等于第一预定表面积,牺牲氧化物层的表面积等于第二预定表面积的部分。 然后进行线性氮掺杂过程,以分别通过第一开口和第二开口将第一和第二预定浓度的氮离子注入第一和第二区域。 此后,分别去除掩模层和牺牲氧化物层。 对第一和​​第二区域中具有不同厚度的两个氧化硅层进行氧化处理。
