摘要:
A plasma ashing method of an object to be processed removes a resist film therefrom in a processing vessel after etching a part of a low dielectric constant film with the resist film having a pattern thereon as a mask in the processing vessel. The plasma ashing method includes a first and a second ashing processes. The first ashing process removes deposits off an inner wall of the processing vessel by using a first processing gas including at least O2 gas while controlling the pressure in the processing vessel to be smaller than or equal to 20 mTorr. The second ashing process removes the resist film by using a second processing gas including at least O2 gas.

摘要:
A plasma etching method is provided for etching a substrate corresponding to an etching object within an etching apparatus that includes a supply condition adjustment unit for adjusting a supply condition for supplying etching gas to the substrate, a temperature adjustment unit for adjusting a temperature of the substrate placed on a stage along a radial direction, and a plasma generating unit for generating plasma within a space between the supply condition adjustment unit and the stage. The plasma etching method includes a control step in which the temperature adjustment unit controls the temperature of the substrate to be uniform within a substrate plane of the substrate, and an adjustment step in which the supply condition adjustment unit adjusts a concentration distribution of active species contained in the plasma generated by the plasma generation unit within the space above the substrate.

A substrate processing apparatus can suppress an edge gas from being diffused toward a center region of a substrate. An upper electrode 200 serving as a gas introducing unit configured to supply one kind of gas or different kinds of gases to a center region and an edge region of the substrate includes a center gas inlet section 204 having a multiple number of gas holes 212 for a center gas; and an edge gas inlet section 206 having a multiplicity of gas holes 214 for an edge gas. By providing a gas hole formation plate 230 having gas holes 232 communicating with the gas holes 214 at a bottom surface of the edge gas inlet section 206, a vertical position of edge gas discharging openings can be adjusted.

A plasma etching apparatus includes a processing chamber; a holding unit for holding the substrate within the processing chamber; an electrode plate facing the holding unit; a plurality of supply parts arranged at different radial positions with respect to the substrate for supplying processing gas to a space between the holding unit and the electrode plate; a high frequency power supply that supplies high frequency power to the holding unit and/or the electrode plate to convert the processing gas supplied to the space into plasma; an adjustment unit that adjusts a supply condition for each of the supply parts; and a control unit that controls the adjustment unit to vary the supply condition between a position where an effect of diffusion of processing gas on an active species concentration distribution at the substrate is dominant and a position where an effect of flow of the processing gas is dominant.

摘要:
A method for detecting an end point of a resist peeling process in which a resist is gasified to be peeled off by producing hydrogen radicals by catalytic cracking reaction where a hydrogen-containing gas contacts with a high-temperature catalyst, and contacting the produced hydrogen radicals with a resist on a substrate, includes monitoring one or more parameters indicating a state of the catalyst and detecting the end point of the resist peeling process based on variations of the monitored parameters. The hydrogen-containing gas may be a H2 gas. The parameters indicating the state of the catalyst may be one or more electrical parameters when a power is supplied to the catalyst. Further, the catalyst may be a filament made of a high melting point metal.

In a magnetic field generator for magnetron plasma generation which comprises a dipole-ring magnet with a plurality of columnar anisotropic segment magnets arranged in a ring-like manner, or in an etching apparatus and a method both of which utilize the magnetic field generator, the uniformity of plasma treatment over the entire surface of a wafer (workpiece) is improved by controlling the direction of the magnetic field relative to the working surface of the wafer (workpiece) which is subject to plasma treatment such as etching.
摘要:
A processing method includes a gas having a Si—CH3 bond supplied into a processing chamber after a target substrate to be processed is loaded into the processing chamber; and a silylation process performed on the target substrate. The internal pressure of the chamber by the supply of the gas having the Si—CH3 bond and the gas supply time are set to be within ranges where the silylation process can be performed while the internal pressure of the chamber is decreased to reach an eligible pressure level where the wafer can be unloaded after the internal pressure of the chamber is increased up to a preset pressure by the supply of the gas.
