Ion beam sample preparation apparatus and methods |
摘要 |
Disclosed are embodiments of an ion beam sample preparation apparatus and methods for using the embodiments. The apparatus comprises a tilting ion beam irradiating means in a vacuum chamber that may direct ions toward a sample, a shield blocking a portion of the ions directed toward the sample, and a shield retention stage with shield retention means that replaceably and removably holds the shield in a position. The shield has datum features which abut complementary datum features on the shield retention stage when the shield is held in the shield retention stage. The tilting ion beam irradiating means may direct ions at the sample from more than one tilt angle. A rotating shield retention stage is also disclosed which works in concert with the tilting ion beam irradiating means.
