    Abstract: Semiconductor wafers are processed in conjunction with a manufacturing execution system using a run-to-run controller and a fault detection system. A recipe is received from the manufacturing execution system by the run-to-run controller for controlling a tool. The recipe includes a setpoint for obtaining one or more target wafer properties. Processing of the wafers is monitored by measuring processing attributes including fault conditions and wafer properties using the fault detection system and one or more sensors. Setpoints of the recipe may be modified at the run-to-run controller according to the processing attributes to maintain the target wafer properties, except in cases when a fault condition is detected by the fault detection system. Thus, data acquired in the presence of tool or wafer fault conditions are not used for feedback purposes. In addition, fault detection models may be used to define a range of conditions indicative of a fault condition. In these cases, the fault detection models may be modified to incorporate, as parameters, setpoints of a recipe modified by a run-to-run controller.

    Abstract: Systems, methods and mediums are provided for dynamic adjustment of sampling plans in connection with a wafer (or other device) to be measured. A sampling plan provides information on specific measure points within a die, a die being the section on the wafer that will eventually become a single chip after processing. There are specified points within the die that are candidates for measuring. The stored die map information may be retrieved and translated to determine the available points for measurement on the wafer. The invention adjusts the frequency and/or spatial resolution of measurements when one or more events occur that are likely to indicate an internal or external change affecting the manufacturing process or results. The increase in measurements and possible corresponding decrease in processing occur on an as-needed basis. The dynamic metrology plan adjusts the spatial resolution of sampling within-wafer by adding, subtracting or replacing candidate points from the sampling plan, in response to certain events which suggest that additional or different measurements of the wafer may be desirable. Where there are provided a number of candidate points in the die map in the area to which points are to be added, subtracted, or replaced, the system can select among the points. Further, the invention may be used in connection with adjusting the frequency of wafer-to-wafer measurements.

    Abstract: The invention relates to a method, system and computer program useful for producing a product, such as a microelectronic device, for example in an assembly line, where the production facility includes parallel production of assembly lines of products on identically configured chambers, tools and/or modules. Control is provided between such chambers. Behaviors of a batch of wafers (or of each wafer) are collected as the first batch (or each wafer) is processed by one of the identically configured chambers in one assembly line to produce the microelectronic device. The information relating to the behavior is shared with a controller of another one (or more) of the identically configured chambers, process tools and/or modules, to provide an adjustment of the process tool and thereby to produce a second batch (or next wafer) which is substantially identical, within tolerance, to the first batch (or wafer).

    Abstract: Semiconductor wafers are processed in a fab in a manner that integrates control at multiple functional unit levels. Examples of functional units include fabs, modules, tools, and the like. Initially, a number of functional unit property targets are received at a functional unit. The functional unit property targets are utilized to generate a number of tool targets for any number of tool level functional units. From there, the tool targets are forwarded to the corresponding tool level functional units. At these tool level functional units, a number of tool recipes, each of which define a number of process setpoints, may be generated by processing the tool targets. The process setpoints define a number of parameters which must be satisfied in order to attain the corresponding tool targets. In addition, in at least some embodiments, the tool targets and tool recipes are determined utilizing feedback information including functional unit states and measurements of controlled parameters.
