摘要:
To provide a cleaning method for an etching apparatus for a metal film that efficiently removes an etching residue deposited in an etching process chamber, assures the reproducibility of the etching performance, and keeps the etching process chamber in a low-dust-emission condition. Each time one workpiece with a metal film is etched (S1), the interior of the vacuum chamber is cleaned by replacing the workpiece with a dummy substrate (S2), performing a first step of plasma processing using oxygen (O2) and carbon tetrafluoride (CF4) to remove a carbon-based deposit pile (S3), and performing a second step of plasma processing using boron trichloride (BCl3) and chlorine (Cl2) to remove a residue that could not be removed by the first step and an etching residue of the metal film (S4).

An improved sample cell for use in a gas analyzer has a sample body with a measuring optical path extending traverse to the cell body. A sample gas inlet port is positioned at one end of the cell body, and a sample gas outlet port is positioned at the other end of the cell body. Porous plates can extend across the cell body, and appropriately-dimensioned apertures in the porous plates can ensure a consistent flow path of gas across the optical path without any stagnated flow patterns.

摘要:
An example method of installing an application onto an apparatus involves displaying an application menu screen comprising a fixed number of menu item display locations, at least one of the menu item display locations displaying a first menu item for an non-installed application. An announcement screen is displayed in response to selection of the first menu item for the non-installed application, the announcement screen comprising a selection item configured to initiate a downloading operation for the non-installed application. The downloading operation is initiated in response to selection of the selection item. The application can be installed/non-installed separately from other applications.
摘要:
Disclosed is a plasma processing method that excels in mass production consistency as it suppresses the flaking of a reaction product deposited on a portion outside the effective range of a Faraday shield in a vacuum vessel. The plasma processing method, which plasma-processes a sample having a layer made of an etch-resistant material by using a plasma processing apparatus having a discharger and a processor, includes a first step of performing an aging process that is to be performed before etching the sample, a second step of performing etching by plasma-processing the layer that is made of an etch-resistant material and formed on the sample, a third step of stabilizing a film deposited on the inner wall of a chamber forming the processor by performing plasma processing after the second step, and an additional step of repeating the second step and the third step.
