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.

摘要:
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.

A pattern formation method suitable for forming micro-patterns using electron beams (EB), X-rays, or extreme ultraviolet radiation (EUV) is provided. The method includes the following steps in the following order: (1) a step of forming and curing a under-layer film containing a radiation-sensitive acid generator which generates an acid upon exposure to radiation on a substrate, (2) a step of irradiating the under-layer film with radiation through a mask to cause an acid to be selectively generated in the exposed area of the under-layer film, (3) a step of forming an upper-layer film which does not contain a radiation-sensitive acid generator, but contains a composition capable of polymerization or crosslinking by the action of an acid, (4) a step of forming a cured film by polymerization or crosslinking selectively in the area of the upper-layer film corresponding to the area of the under-layer film in which the acid has been generated, and (5) a step of removing the area of the upper-layer film corresponding to the area of the under-layer film in which the acid has not been generated.

An image forming apparatus has a chassis, a paper feed roller, a lifting member, and a biasing member. The chassis has a first side surface, a second side surface, and a bottom surface that connects the first and second side surfaces. The bottom surface has one of a first L-shaped projecting portion and a first coupling hole unitarily formed thereon. The paper feed roller is rotatably supported by the first and second side surfaces of the chassis and configured to convey paper. The lifting member is pivotably supported by the bottom surface of the chassis, and has a main portion and the other of the first L-shaped projecting portion and the first coupling hole unitarily formed on the main portion. The first L-shaped projection is pivotably coupled to the first coupling hole, such that the lifting member is pivotably coupled to the bottom surface.

Idler mechanism includes a pickup roller gear; a third pickup gear that meshes with the pickup roller gear; a pickup idler arm that is capable of pivoting around a pivot axis between the pickup roller gear side and the third pickup gear side; first and second pickup idler gears disposed at ends of the pickup idler arm; and a second pickup gear that rotates around a pivot axis and drives the first and second pickup idler gears. The first pickup idler gear meshes with the pickup roller gear when the pickup idler arm is pivoted toward the pickup roller gear, while the second pickup idler gear meshes with the third pickup gear when the pickup idler arm is pivoted toward the third pickup gear. At least one of the first and second pickup idler gears is always meshing with respective one of the pickup roller gear and the third pickup gear.
