摘要:
A chemical mechanical polishing (CMP) method is disclosed in which a new polishing pad is broken-in and conditioned into a steady operating state while using a silica (SiO2) based CMP slurry and where the broken-in and conditioned pad is afterwards used for polishing patterned workpieces (e.g., semiconductor wafers) with a ceria (CeO2) based CMP slurry. The approach shortens break-in time and appears to eliminate a first wafer effect usually seen following break-in with ceria-based CMP slurries.

摘要:
A chemical mechanical polishing (CMP) method is disclosed in which a torque-based end-point algorithm is used to determine when polishing should be stopped. The end-point algorithm is applicable to situations where a ceria (CeO2) based CMP slurry is used for further polishing, pre-patterned and pre-polished workpieces (e.g., semiconductor wafers) which have a high friction over-layer (e.g., HDP-oxide) and a comparatively, lower friction and underlying layer of sacrificial pads (e.g., silicon nitride pads). A mass production wise, reliable and consistent signature point in the friction versus time waveform of a torque-representing signal is found and used to trigger an empirically specified duration of overpolish. A database may be used to define the overpolish time as a function of one or more relevant parameters.

A chemical mechanical polishing method is disclosed in which a batch of wafers is first supplied to a low-selectivity, first CMP tool for partly polishing the batch with one or more relatively non-selective CMP slurries (e.g., silica (SiO2) based); and in which the batch of partly-polished wafers is subsequently transferred to a higher-selectivity, second CMP tool which uses one or more comparatively more-selective CMP slurries (e.g., ceria (CeO2) based) to further the polishing of the batch of partly-polished wafers and/or to complete the polishing of the partly-polished wafers.

摘要:
When using graphical diagrams, cutting and pasting operations may take advantage of predefined relationships to intelligently insert and remove items from the diagram. A text data model may be interpreted sequentially or hierarchically to construct various diagrams. Pasting operations will bring new data into the diagram and data model while conforming the new data to the diagram definition. Cutting operations may cause the data model and diagram to be healed to conform to the diagram definition.
摘要:
A method and computer-readable medium are provided for fitting text to shapes within a graphic. According to the method, initial constraints are defined that comprise initial values describing how a shape and text within the shape should be laid out. Constraint rules are also defined for use in modifying the initial constraints when application of the initial constraints to the text in a shape results in the text overflowing the boundaries of the shape. A change may be detected to the graphic that would affect the size or position of one or more of the shapes or the text within one of the shapes. If such a change causes text to overflow when laid out using the initial constraints, the constraint rules are applied sequentially to modify the constraints. The modified constraints are then reapplied to the shapes to create a new layout for the graphic.
摘要:
System and methods for providing 1D and 2D connectors in a connected diagram. Routing and layout of connectors is accomplished through a pre-defined set of behaviors and properties on a connector that enable an aesthetic layout. Routing behaviors and visual look of the connectors within a diagram may be included in an XML definition file or controlled by a user. The user may switch between 1D and 2D connectors regardless of a shape of the connector. Padding and offset features are assigned to connectors for aesthetically pleasing presentation of object relations. Text box shapes and placements on or near connectors are aligned with connector type, size, and placement. Images and non-predefined shapes may be used as connectors with behaviors assigned similar to predefined shapes.
摘要:
A system, a user interface and computer-readable media for associating metadata with digital media. Tags are associated with single-action user inputs. Entry of one of the single-action user inputs is detected. The tag associated with the detected input is stored as metadata associated with a selected item of digital media.
