【Abstract】 Some problems of vacuum system for KZ-400 ion beam etching system were put forward and solved. Reasonable configuration of vacuum system were chosen and ANSYS was used to analyze and calculate the deformations of the vacuum chamber in different structures, based on which the structure was optimized with reasonable compensation measures taken. Experiments and mass spectrum analysis were made to test the performance in vacuum of a MoS 2 lubricant so as to lubricate (efficiently) the scanning movement for working table.更多还原
