摘要:
Methods of polymer deposition for forming reduced critical dimensions are described. In one embodiment, a substrate is provided into a chamber, the substrate having a patterned layer disposed on an underlying layer formed thereon. The patterned layer includes a plurality of openings, each opening having a sidewall, a bottom, and a critical dimension. A gas mixture is provided into the chamber, the gas mixture having an etching gas and a polymer control gas. The polymer control gas includes a polymerizing fluorocarbon CxFy gas and a C—H bond containing gas. A plasma is formed with the gas mixture and a conformal polymer layer is deposited in the presence of the plasma on the patterned layer to form a reduced critical dimension in each opening. The reduced critical dimension is smaller than the corresponding critical dimension of the opening.

One or more openings in an organic mask layer deposited on a first insulating layer over a substrate are formed. One or more openings in the first insulating layer are formed through the openings in the organic mask using a first iodine containing gas. An antireflective layer can be deposited on the organic mask layer. One or more openings in the antireflective layer are formed down to the organic mask layer using a second iodine containing gas. The first insulating layer can be deposited on a second insulating layer over the substrate. One or more openings in the second insulating layer can be formed using a third iodine containing gas.
摘要:
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.

Boron-doped carbon-based hardmask etch processing is described. In an example, a method of patterning a film includes etching a boron-doped amorphous carbon layer with a plasma based on a combination of CH4/N2/O2 and a flourine-rich source such as, but not limited to, CF4, SF6 or C2F6.

摘要:
The image forming apparatus includes a chassis, a paper guide, a paper feed roller, and a paper supply portion from which the paper feed roller is configured to supply paper. The paper guide is supported within the chassis and has a base portion and a first separation portion that projects from the base portion. The paper feed roller is rotatably supported by the chassis. The paper supply portion has a guide projection on its first lateral side portion. The widthwise center of the paper feed roller is offset toward the first lateral side relative to the widthwise center of the first separation portion.
