Method and system for evaluating a machine tool operating characteristics
A method and system for evaluating a performance of a semiconductor manufacturing tool while manufacturing microelectronic devices are disclosed. At least one report is generated based on executions of at least one statistical test. The report includes at least one heat map having rows that correspond to sensors, columns that correspond to trace data obtained during recipe steps, and cells at the intersection of the rows and the columns. At least one sensor in the tool obtains trace data of a recipe step while manufacturing at least one microelectronic device. A computing device analyzes the obtained trace data to determine a level of operational significance found in the data and assigns a score to the trace data that indicates a level of operational significance. Then, the computing device places the score in a corresponding cell of the heat map. A user uses the cell for evaluating the tool performance.

InactiveUS20050238451A1Accurate centerAvoid turningSleeve/socket jointsTransportation and packagingSet screwEngineering
A system for mounting a tool in a tool holder combining a means for high-precision centering of the tool and a means for positive restraint of the tool from rotation within the tool holder. The tool holder includes a cylindrical aperture having a diameter slightly less than the diameter of the shank of a cylindrical tool. The tool is installed into the tool holder by heating the tool holder to a temperature sufficient to increase the pocket diameter sufficiently to accept the tool shank. In a first shrink-fit embodiment, the tool shank is further provided with an angular flat for engagement with a set screw to prevent the tool from being turned in the holder in use. In a second shrink-fit embodiment, a groove extending partially around the tool receives a tangential pin through a passage in the tool holder. The tool is rotated in the holder until the pin binds in the groove, thus preventing any further rotation of the tool in the holder during use.
