  • Patent number: 8452441
    Abstract: The invention discloses a process quality prediction system and a method thereof. When a processing apparatus performs a process on a target, the process is measured by a measurement apparatus to receive a process value. The process value and several previous quality data collected from the measurement apparatus are used to predict the quality of the product which is processing inline. The method is composed of a moving window, a stepwise regression scheme and an analysis of covariance (ANCOVA). The drift and shift of process are overcome by the moving window. A key variable set is selected by the stepwise regression scheme and a virtual model is identified by the analysis of covariance.

  • Patent number: 8429100
    Abstract: The invention discloses a method for building adaptive soft sensor. The method comprises the following steps. The input and schedule vectors are constructed, and a novel learning algorithm that uses online subtractive clustering is used to recursively update the structure and parameters of a local model network. Three rules are proposed for updating centers and local model coefficients of existing clusters, for generating new clusters and new models as well as for merging existing clusters and their corresponding models. Once verified, the online inferential model can be created to generate the predicted value of process. Thus, it does not need much memory space to process the method and can be easily applied to any other machine.

  • Publication number: 20120016643
    Abstract: The present invention discloses a virtual measuring system and a method thereof for predicting the quality of thin film transistor liquid crystal display processes. The virtual measuring method comprises the steps of: capturing a plurality of process parameter data from at least one process machine by an advanced process control unit; normalizing the process parameter data by an original data processing unit; picking a plurality of key process parameter data from the process parameter data by a key parameter choosing unit; establishing a virtual measuring model by a predicting unit according to the key process parameter data, and generating a virtual measuring data by the virtual measuring model. The virtual measuring model is established after a disturbing coefficient is generated through a time sequence regression algorithm by the predicting unit.

  • Patent number: 7187990
    Abstract: The architecture of the controller of the present invention is mainly composed of three portions, which are a model predictive controller, a local controller (also called stably assistant controller), and a coordinator. This modified model predictive control structure merges two control loops by a coordinator. The control mode can be switched into either of them or provide a combined control action by adjustments of the coordinator. When the system moves out the range of the database, the coordinator will automatically detect the fault and switch to the stably assistant controller to provide the basic control quality to ensure the safety.
