  • Publication number: 20140213062
    Abstract: Multilayered stacks having layers of silicon interleaved with layers of a dielectric, such as silicon dioxide, are plasma etched with non-corrosive process gas chemistries. Etching plasmas of fluorine source gases, such as SF6 and/or NF3 typically only suitable for dielectric layers, are energized by pulsed RF to achieve high aspect ratio etching of silicon/silicon dioxide bi-layers stacks without the addition of corrosive gases, such as HBr or Cl2. In embodiments, a mask open etch and the multi-layered stack etch are performed in a same plasma processing chamber enabling a single chamber, single recipe solution for patterning such multi-layered stacks. In embodiments, 3D NAND memory cells are fabricated with memory plug and/or word line separation etches employing a fluorine-based, pulsed-RF plasma etch.

  • Patent number: 8771923
    Abstract: A radiation-sensitive composition includes a low-molecular-weight compound, a solvent and a radiation-sensitive acid-generator other than the low-molecular-weight compound. The low-molecular-weight compound has one or more acid-dissociable groups which decompose by an action of an acid to enhance solubility in an alkaline developing solution and one or more radiation-sensitive acid-generating groups which generate an acid upon application of an active ray or radiation per molecule. The low-molecular-weight compound has a polystyrene-reduced number-average molecular weight (Mn) measured by gel permeation chromatography (GPC) of 500 to 4,000. The low-molecular-weight compound is not obtained from chain growth polymerization of a monomer with an unsaturated bond. A content of the low-molecular-weight compound is 80 mass % or more of 100 mass % of a total solid component of the radiation-sensitive composition. The low-molecular-weight compound is a compound shown by a following formula (1).

  • Patent number: 8450045
    Abstract: A pattern forming method includes providing and curing a under-layer film containing a radiation-sensitive acid generator which generates an acid upon exposure to radiation on a substrate. The under-layer film is irradiated with radiation through a mask to cause an acid to be selectively generated in an exposed area of the under-layer film. An upper-layer film which does not contain a radiation-sensitive acid generator and which contains a composition capable of polymerizing or crosslinking by an action of an acid is provided. A cured film is provided by polymerization or crosslinking selectively in an area of the upper-layer film corresponding to the exposed area of the under-layer film in which the acid has been generated. An area of the upper-layer film corresponding to an area of the under-layer film in which the acid has not been generated is removed.
