Like Driving a Car: Acquiring Quality SEM/FESEM Images in Different Situations
Online Presentations | 18 Nov 2022 | Contributor(s):: Bangzhi Liu, NACK Network
Getting good SEM/FESEM images is dependent on both the sample conditions (conductivity, bulk vs. thin film, etc) and the instrument’s imaging parameters (e.g., beam voltage, beam current, working distance, detector, etc). This webinar will simplify and explain the complex nature...
