Latest Patents
One of Heng Hao's latest patents is titled "Deep auto-encoder for equipment health monitoring and fault detection in semiconductor and display process equipment tools." This invention relates to a method for detecting anomalies in time-series traces received from sensors of manufacturing tools. The process involves a server that feeds a set of training time-series traces to a neural network, which is configured to derive a model that minimizes reconstruction error. The server extracts input time-series traces from sensors associated with manufacturing tools that produce silicon substrates. By feeding these traces to the trained neural network, the server generates output time-series traces based on the model. It then calculates the mean square error between the input and output traces, declaring a sensor as having an anomaly when the error exceeds a predetermined value.
