This invention discloses a method for self-learning the clutch of an AMT (Automated Manual Transmission) in commercial vehicles, specifically including the following steps: Step 1: Determine whether the current vehicle meets the self-learning conditions; if so, proceed to Step 2; Step 2: Clutch self-learning: After activating clutch self-learning, the clutch will perform two rounds of disengagement and engagement; Step 3: After the clutch performs two disengagement and engagement actions, the learned parameters are stored in the TCU (Tracking Control Unit), completing one clutch self-learning cycle; Step 4: Repeat the above process to complete multiple clutch self-learning cycles. The method of this invention defines the complete disengagement point and the first, second, and third contact points by using the input shaft speed as a threshold, resulting in higher recognition accuracy and a simpler and more efficient TCU judgment and calculation logic.

This invention provides an electrostatic chuck and semiconductor processing equipment. The electrostatic chuck includes an annular air passage, a main air passage group, and a secondary air passage group. The annular air passage is located near the edge of the upper surface of the chuck body, defining a heat exchange area within it. The main air passage group surrounds a central air inlet, and the secondary air passage group surrounds the main air passage group. The main air passage group is connected to both the central air inlet and the secondary air passage group, and is configured to increase the speed at which the back-blown gas flowing from the central air inlet is delivered to the secondary air passage group. The secondary air passage group is connected to both the main air passage group and the annular air passage, and is configured to ensure uniform distribution of the back-blown gas at different locations within the heat exchange area. The electrostatic chuck and semiconductor processing equipment provided by this invention can effectively shorten the back-blown gas passage time while ensuring the stability and uniformity of the back-blown gas pressure, thereby increasing equipment productivity.
