Real-time anomaly detection and classification during semiconductor processing
A method of detecting and classifying anomalies during semiconductor processing includes executing a wafer recipe a semiconductor processing system to process a semiconductor wafer; monitoring sensor outputs from a sensors that monitor conditions associated with the semiconductor processing system; providing the sensor outputs to models trained to identify when the conditions associated with the semiconductor processing system indicate a fault in the semiconductor wafer; receiving an indication of a fault from at least one of the models; and generating a fault output in response to receiving the indication of the fault.
SYSTEMS AND METHODS FOR ANOMALY RECOGNITION AND DETECTION USING LIFELONG DEEP NEURAL NETWORKS
Industrial quality control is challenging for artificial neural networks (ANNs) and deep neural networks (DNNs) because of the nature of the processed data: there is an abundance of consistent data representing good products, but little data representing bad products. In quality control, the task is changed from conventional DNN task of “recognize what I learned best” to “recognize what I have never seen before.” Lifelong DNN (L-DNN) technology is a hybrid semi-supervised neural architecture that combines the ability of DNNs to be trained, with high precision, on known classes, while being sensitive to any number of unknown classes or class variations. When used for industrial inspection, L-DNN exploits its ability to learn with little and highly unbalanced data. L-DNN's real-time learning capability takes advantage of rare cases of poor-quality products that L-DNN encounters after deployment. L-DNN can be applied to industrial inspections and manufacturing quality control.
PRODUCT INSPECTION DEVICE, PRODUCT INSPECTION METHOD, AND COMPUTER PROGRAM
A product inspection device and method for correctly calculating consumer and producer risks irrespective of the type of distribution of products. A characteristic value representing a predetermined product characteristic is measured for each product as a product measurement value, and a standard deviation of measurement variations in measurement results is calculated as a measurement value standard deviation. The products are determined to be conforming based on whether the measured product measurement value falls within a range of a product standard. Consumer and producer risks are calculated based on the measurement variations. The calculated consumer and producer risks are respectively and successively added up and it is determined whether the number of products having undergone the adding have reached a predetermined number. If so, the added up consumer risk and producer risk are divided by the number of products to calculate a final consumer risk and a final producer risk.
ESTIMATION OF CHAMBER COMPONENT CONDITIONS USING SUBSTRATE MEASUREMENTS
A method includes processing a substrate in a process chamber according to a recipe, wherein the substrate comprises at least one of a film or a feature after the processing. The method further includes generating a profile map of the first substrate. The method further includes processing data from the profile map using a first model, wherein the first model outputs at least one of an estimated mesa condition of a substrate support for the process chamber, an estimated lift pin location condition of the substrate support an estimated seal band condition of the substrate support, or an estimated process kit ring condition for a process kit ring for the process chamber. The method further includes outputting a notice as a result of the processing.
METHOD FOR DETERMINING THE LEVEL OF UNUSUALNESS OF INDIVIDUALS, IN PARTICULAR IN ORDER TO STATISTICALLY DETECT UNUSUAL INDIVIDUALS IN A MULTIVARIATE CONTEXT
A method for determining the level of unusualness of individuals, in particular in order to statistically detect unusual individuals in a set of previously gathered data resulting from measurements of parameters of individuals taken by a plurality of measuring systems. The data is pre-processed, and a multivariate unusualness index is determined. The index being transformed by a function so as to be between 0 and 1, on the set of measurements for each individual based on the preprocessed data. Unusual individuals are then identified.
