A reactor for plasma-assisted chemical vapor deposition includes a plasma duct for containing one or more substrates to be coated by ions; an arc discharge generation system for generating a flow of electrons through the plasma duct from a proximal end toward a distal end of the plasma duct; a gas inlet coupled to the distal end for receiving a reactive gas; a gas outlet coupled to the proximal end for removing at least a portion of the reactive gas to generate a flow of the reactive gas through the plasma duct from the distal end toward the proximal end, to generate the ions from collisions between the electrons and the reactive gas; and a separating baffle positioned for restricting flow of the reactive gas out of the plasma duct to maintain a high pressure in the plasma duct to increase rate of deposition of the ions onto the substrates.

A process kit ring for use in a plasma processing system is disclosed herein. The process kit ring includes an annular body and one or more hollow inner cavities. The annular body is formed from a plasma resistant material. The annular body has an outer diameter greater than 200 mm. The annular body includes a top surface and a bottom surface. The top surface is configured to face a plasma processing region of a process chamber. The bottom surface is opposite the top surface. The bottom surface is substantially perpendicular to a centerline of the body. The bottom surface is supported at least partially by a pedestal assembly. The one or more hollow inner cavities are formed in the annular body about the centerline. The one or more hollow inner cavities are arranged in a circle within the annular body.

Plasma process chambers employing distribution grids having focusing surfaces thereon enabling angled fluxes to reach a substrate, and associated methods are disclosed. A distribution grid is disposed in a chamber between the plasma and a substrate. The distribution grid includes a first surface facing the substrate and a focusing surface facing the plasma. A passageway extends through the distribution grid, and is sized with a width to prevent the plasma sheath from entering therein. By positioning the focusing surface at an angle other than parallel to the substrate, an ion flux from the plasma may be accelerated across the plasma sheath and particles of the flux pass through the passageway to be incident upon the substrate. In this manner, the angled ion flux may perform thin film deposition and etch processes on sidewalls of features extending orthogonally from or into the substrate, as well as angled implant and surface modification.

Provided is a substrate treating apparatus, which includes a plasma generating part configured to generate plasma, a housing disposed under the plasma generating part, and having a space therein, a susceptor disposed within the housing and supporting a substrate, and a baffle including injection holes injecting the plasma supplied from the plasma generating part, to the substrate. The baffle includes a base in which the injection holes are formed, and a central portion of the base is thicker than an edge thereof.

A deposition apparatus includes a chuck in a process chamber, the chuck having a top surface on which a substrate is loaded, a showerhead disposed over the chuck, and a fence extension disposed in the process chamber. Plasma is generated in a space between the showerhead and the loaded substrate during a deposition process. The fence extension at least partially confines the plasma in the space during the deposition process, thereby enabling improved thickness uniformity and reliability of a layer deposited on the loaded substrate during the deposition process.

A method includes forming a coating layer in a dry etching chamber, placing a wafer into the dry etching chamber, etching a metal-containing layer of the wafer, and moving the wafer out of the dry etching chamber. After the wafer is moved out of the dry etching chamber, the coating layer is removed.

A plasma-enhanced chemical vapour deposition (PE-CVD) apparatus includes a chamber including a circumferential pumping channel, a substrate support disposed within the chamber, one or more gas inlets for introducing gas into the chamber, a plasma production device for producing a plasma in the chamber, and an upper and a lower element positioned in the chamber. The upper element is spaced apart from the substrate support to confine the plasma and to define a first circumferential pumping gap, and the upper element acts as a radially inward wall of the circumferential pumping channel. The upper and lower elements are radially spaced apart to define a second circumferential pumping gap which acts as an entrance to the circumferential pumping channel, in which the second circumferential pumping gap is wider than the first circumferential pumping gap.
摘要:
An ICP A plasma reactor having an enclosure wherein at least part of the ceiling forms a dielectric window. A substrate support is positioned within the enclosure below the dielectric window. An RF power applicator is positioned above the dielectric window to radiate RF power through the dielectric window and into the enclosure. A plurality of gas injectors are distributed uniformly above the substrate support to supply processing gas into the enclosure. A circular baffle is situated inside the enclosure and positioned above the substrate support but below the plraity of gas injectors so as to redirect the flow of the processing gas.
