    摘要: Embodiments of the present invention pertain to methods of forming features on a substrate using a self-aligned triple patterning (SATP) process. A stack of layers is patterned near the optical resolution of a photolithography system using a high-resolution photomask. The heterogeneous stacks are selectively etched to undercut a hard mask layer beneath overlying cores. A dielectric layer, which is flowable during formation, is deposited and fills the undercut regions as well as the regions between the heterogeneous stacks. The dielectric layer is anisotropically etched and a conformal spacer is deposited on and between the cores. The spacer is anisotropically etched to leave two spacers between each core. The cores are stripped and the spacers are used together with the remaining hard mask features to pattern the substrate at triple the density of the original pattern.

    摘要: Embodiments of the present invention pertain to methods of forming patterned features on a substrate having a reduced pitch in two dimensions as compared to what is possible using standard photolithography processing techniques using a single high-resolution photomask. A spacer layer is formed over a two-dimensional square grid of cores with a thickness chosen to leave a dimple at the center of four cores on the corners of a square. The spacer layer is etched back to reveal the substrate at the centers of the square. Removing the core material results in double the pattern density of the lithographically defined grid of cores. The regions of exposed substrate may be filled again with core material and the process repeated to quadruple the pattern density.

    摘要: Embodiments of the present invention pertain to methods of forming features on a substrate using a self-aligned double patterning (SADP) process. A conformal layer of non-sacrificial material is formed over features of sacrificial structural material patterned near the optical resolution of a photolithography system using a high-resolution photomask. An anisotropic etch of the non-sacrificial layer leaves non-sacrificial ribs above a substrate. A gapfill layer deposited thereon may be etched or polished back to form alternating fill and non-sacrificial features. No hard mask is needed to form the non-sacrificial ribs, reducing the number of processing steps involved.

    摘要: Methods of forming high-current density vertical p-i-n diodes on a substrate are described. The methods include the steps of concurrently combining a group-IV-element-containing precursor with a sequential exposure to an n-type dopant precursor and a p-type dopant precursor in either order. An intrinsic layer is deposited between the n-type and p-type layers by reducing or eliminating the flow of the dopant precursors while flowing the group-IV-element-containing precursor. The substrate may reside in the same processing chamber during the deposition of each of the n-type layer, intrinsic layer and p-type layer and the substrate is not exposed to atmosphere between the depositions of adjacent layers.
