Embodiment Construction
[0035] As stated in the background technology, it takes a long time to replace the ion vacuum timer and reset it.
[0036] The study found that the existing ion vacuum gauge is directly connected to the vacuum chamber, and the ion vacuum gauge must continuously monitor the vacuum condition in the vacuum chamber. In addition, the ion implantation equipment needs regular maintenance, and the vacuum chamber needs to be checked repeatedly during regular maintenance. The ion vacuum gauge will be repeatedly exposed to the atmosphere and foreign matter, which will affect the ion vacuum gauge and cause the ion vacuum gauge to be abnormal or damaged. When the ion vacuum gauge is abnormal or damaged, the ion implantation equipment will stop the injection immediately. Personnel just must shut down, close relevant vacuum pump one by one (vacuum pump is connected with vacuum chamber, to guarantee the vacuum degree in the vacuum chamber), and the vacuum chamber is exhausted so that the press...
