摘要： A method for reducing the fogging effect in an electron beam lithography system wherein the exposure is controlled in order to obtain resulting pattern after processing which conforms to design data. A model for the fogging effect is fitted by individually changing at least the basic input parameters of the control function, the function type is chosen in accordance to the Kernel type used in the proximity corrector. The proximity effect is considered as well and an optimized set of parameters is obtained in order to gain a common control function for the proximity and fogging effect. The pattern writing with an e-beam lithographic system is controlled by the single combined proximity effect control function and the fogging effect control function in only one data-processing step using the same algorithms as are implemented in a standard proximity corrector.

摘要： A process for controlling the proximity effect correction in an electron beam lithography system. The exposure is controlled in order to obtain resulting pattern after processing which is conform to design data. In a first step an arbitrary set patterns is exposed without applying the process for controlling the proximity correction. The geometry of the resulting test structures is measured and a set of measurement data is obtained. Within a numerical range basic input parameters for the parameters α, β and η, are derived from the set of measurement data. A model is fitted by individually changing at least the basic input parameters α, β and η of a control function to measurement data set and thereby obtaining an optimised set of parameters. The correction function is applied to an exposure control of the electron beam lithography system during the exposure of a pattern according to the design data.

摘要： An embodiment of a method of dividing past computing instances into predictable and unpredictable sets begins with a first step of a computing entity storing a training data set comprising past computing instances. Each past computing instance comprises attributes and a past computing value. In a second step, the computing entity separates the training data set into a predictable set of past computing instances and an unpredictable set of past computing instances. According to an embodiment, a method of predicting a computing value begins with the first and second steps. The method of predicting the computing value continues with a third step of the computing entity forming a predictor from the predictable set of past computing instances. In a fourth step, the computing entity applies the predictor to a pending computing instance that meets a predictability test to determine a predicted value for the pending computing instance.

摘要： A method for generating a demand estimate for a product includes gathering a set of auction data which is relevant to the product, removing from the auction data all but a highest bid from each unique bidder in the auction data, and correcting a bias in the auction data caused by a set of characteristics of an auction from which the auction data is obtained. In one embodiment, the auction data is obtained from an on-line auction which is characterized by bidders not necessarily knowing the start time of the auction.
