Latest Patents

Kai Liu holds a patent titled "Model-based control of substrate processing systems." This invention discloses a system for controlling a parameter of a plant associated with a substrate processing chamber. The system includes a measuring circuit that assesses the response of the plant when the parameter is altered. A model generating circuit determines the delay and gain of the plant based on this response. Furthermore, it generates a model of the plant using the delay, gain, and a time constant. A predicting circuit then utilizes this model to generate a prediction of the parameter, which is compared to a set point to produce a control signal for managing the plant's parameter.
