[0002] The semiconductor process chamber is a key piece of equipment in the semiconductor manufacturing process. It is mainly used to carry out chemical reactions such as material deposition and etching under vacuum conditions. It consists of several key components, including reaction chamber, vacuum sealing interface, gas nozzle, heating element, etc. The manufacturing precision and material selection of these components have a direct impact on the performance of the reaction chamber and the quality of the reaction.

[0003] The components of a semiconductor process chamber include a vacuum-sealed interface, which is used to ensure a high vacuum environment within the reaction chamber and prevent the leakage of reaction gases and the entry of impurities. Therefore, in order to detect the vacuum status at this location, a corresponding vacuum detector is required. Nowadays, most vacuum detectors obtain data by means of digital or pointer deflection. If the dial is blurred due to external influences, it can directly affect the operator's reading and affect the detection effect. Utility Model Content

This improves the overall warning capability during the operation.

[0015] (2) By fixing the connecting rod at the bottom of the connecting block, and installing the first telescopic rod on both sides of the connecting rod, the side clamp can be pushed to move laterally after the first telescopic rod is in operation. Therefore, the spacing of different side clamps can be adjusted according to the detection position. Then, the clamp is used to clamp the two sides of the detection point. The clamp is installed on the side of the side clamp with mounting bolts, which facilitates the replacement of the clamp. Therefore, the overall assembly and clamping ability is improved in the working process.

[0016] (3) By opening a straight groove inside the connecting rod, and the bottom of the straight groove is connected to the connecting groove, when assembling the detection probe, since the top of the detection probe is fixed with the connecting post, the connecting post can be used to complete the connection and assembly with the connecting groove, which facilitates the assembly of the detection probe at the lower position of the connecting rod, thereby improving the overall connection capability.
