To ensure production safety, the timing blowing can only be enabled when there is no wafer being measured on the machine.
[0059] Alternatively, the controller can set different automatic blowing modes such as continuous blowing mode or intermittent blowing mode, for example, the first half of the time adopts intermittent blowing mode, and the second half of the time adopts continuous blowing mode. Alternatively, the controller can use a timer, an integrated circuit chip, or a single-chip microcomputer, etc.
[0060] The controller can realize the timing cleaning of the electrostatic chuck 10 by controlling the start timing of the air jet assembly 2, the air jet duration of the air jet assembly 2, and the resting time of the air jet assembly 2, and can accurately control the operating state of the air jet assembly 2, thereby improving the cleaning effect and avoiding excessive blowing of particles floating in the cavity.

[0065] Specifically, the first bracket 11 and the second bracket 12 can each comprise a stepped portion or an inclined connecting plate to reduce the mounting height of the jet pipe 21, so that the jet pipe 21 is located between the mounting platform 101 and the electrostatic chuck 10. The mounting slot 102 extends through the mounting platform 101 along the first direction x, and after the bracket assembly 1 is mounted at both ends of the mounting slot 102, the mounting platform is sealed by a cover plate to make the cavity 20 of the semiconductor production equipment airtight. The length of the second bracket 12 is less than the length of the first bracket 11, so that the jet assembly 2 is located directly above the electrostatic chuck 10.
