摘要： A method for detecting during a planarization process the removal of a first layer of material overlying a workpiece is provided. Relative motion is effected between the first layer and a working surface to remove the first layer. A light having a spectrum of wavelengths is transmitted to the workpiece. The intensity for each of a plurality of reflected wavelengths of a reflected light reflected from the workpiece is measured to obtain a spectrum. The spectrum is a function of the plurality of reflective wavelengths. A spectrum reference value is calculated and a plurality of spectrum difference values are calculated by subtracting the spectrum reference value from the spectrum. An absolute value for each of the plurality of spectrum difference values that is a function of one of the plurality of reflected wavelengths that falls within a selected range of wavelengths is summed together to obtain a delta value. An endpoint parameter is calculated from the delta value.

摘要： A method of reducing distortion in a spray formed rapid tool includes the steps of making a model of a desired tool and constructing a ceramic pattern as the inverse of the model. The method also includes the steps of building a thermal model of the desired tool from a solid model of the ceramic pattern and applying thermal boundary conditions to the thermal model based on known conditions. The method also includes the steps of running the thermal model to produce a temperature distribution of the desired tool and determining any temperature deviations in the temperature distribution above a predetermined value. The method further includes thermally spraying a metal material against the ceramic pattern to form the desired tool if there are no temperature deviations in the temperature distribution above the predetermined value.

摘要： Methods and systems for monitoring a parameter of a measurement device during polishing, damage to a specimen during polishing, a characteristic of a polishing pad, or a characteristic of a polishing tool are provided. One method includes scanning a specimen with a measurement device during polishing of a specimen to generate output signals at measurement spots on the specimen. The method also includes determining if the output signals are outside of a range of output signals. Output signals outside of the range may indicate that a parameter of the measurement device is out of control limits. In a different embodiment, output signals outside of the range may indicate damage to the specimen. Another method includes scanning a polishing pad with a measurement device to generate output signals at measurement spots on the polishing pad. The method also includes determining a characteristic of the polishing pad from the output signals.

摘要： A method is described for determining an oilfield parameter for a drilling operation in an oilfield, the oilfield having a well site with a drilling tool advanced into a subterranean formation with geological structures and reservoirs therein. A first set of decision factors and a second set of decision factors about the drilling operation are identified. Each of the first set of decision factors is contained within a first set of nodes, and each of the second set of decision factors is contained within a second set of nodes. Both the first set of nodes and the second set of nodes contain a set of common nodes, which are common to both the first and second sets. The first set of nodes is associated to create a first belief network and the second set of nodes is associated to create a second belief network. Then, the set of common nodes of the first belief network is associated with the set of common nodes of the second belief network to form a multinet belief network. Oilfield parameter can be generated from the multinet belief network.
