摘要:
An object to be processed has a structure having an SiC film and an organic Si-low dielectric constant film formed on the SiC film. The SiC film is etched using a plasma produced from an etching gas and using the organic Si low-dielectric constant film as a mask. The etching gas contains CH2F2 or CH3F.

摘要:
A plasma etching method includes the steps of exciting an etching gas introduced in a processing vessel into a plasma, the etching gas including 1,1,1,4,4,5,5,5-octafluoro-2-pentyne, and carrying out a plasma etching on a film on a target object accommodated in the processing vessel via opening patterns of a resist mask on the film. Therefore, it is possible to perform plasma etching having a high selectivity to resist and/or suppressing the etch stop.

摘要:
Disclosed is a technology in which a nozzle part is mounted in a vacuum chamber and a silicon substrate is held to face a discharge hole of the nozzle part. For example, ClF3 gas and Ar gas are supplied from the nozzle part and the mixed gas is discharged from the nozzle part under a vacuum atmosphere. By doing this, the mixed gas is adiabatically expanded and the Ar atoms or ClF3 molecules are combined, which become a gas cluster. The gas cluster is irradiated to the surface of the silicon substrate without being ionized and, as a result, the surface of the silicon surface becomes a porous state. Then, lithium is grown on the surface of the silicon substrate in a separate vacuum chamber 41 by sputtering without breaking the vacuum.

A substrate processing apparatus which irradiates a substrate under processing with an electron beam and processes the substrate with the electron beam is disclosed. The substrate processing apparatus includes an electron beam generation mechanism which generates the electron beam, first area having a plurality of first static electricity deflecting devices whose thicknesses gradually increase in a traveling direction of the electron beam, and a second area disposed on a downstream side of the electron beam of the first area and having a plurality of second static electricity deflecting devices whose thicknesses are nearly same in the traveling direction of the electron beam. The substrate processing apparatus may further include a plurality of lenses whose thicknesses gradually decrease in the traveling direction of the electron beam, at least one of the plurality of lenses being disposed in each of the first area and the second area.
摘要:
A plasma etching method is performed by plasma etching an SiN layer through a mask layer to form a first wiring portion and a second wiring portion, the first and the second wiring portions having different wiring densities in the etched SiN layer, the mask having two pattern portions respectively corresponding to the first and the second wiring portions. In the plasma etching step, by using an etching gas including fluorocarbon and C2H2F4, the line width variation between the first and the second wiring portions is restrained.

摘要:
A plasma processing method is conducted while a thickness of a resist film being monitored, thereby preventing the thickness of the resist film from being reduced. The plasma processing method includes steps of supplying a processing gas into an airtight processing chamber, and plasma-processing a target layer formed on an object to be processed by using a resist film as a mask. The method includes a main etching process (first process) of plasma-processing the target layer while the thickness of the resist film being monitored until the reduction rate of the thickness of the resist film reaches a predetermined value, and an over-etching process (second process) of plasma-processing the target layer in a changed process condition in which selectivity against the resist film is higher than in the first process.
