Evaluation of the Electric Field above a Specimen Surface during SIMS Analysis.

Abstract

The electric field above specimen surfaces mounted in specimen holders was investigated. After confirming an agreement of the field distortion area obtained from SIMS experiments using a Cameca IMS-4f ion microscope and computer simulation, the field distortions above specimen surfaces of various types of holder were estimated. Two findings were obtained: (i) the field distortion area near to the window edge of the holder increases along with an increase in the faceplate thickness of the holder, and (ii) a holder with a tapered faceplate produces a more uniform electric field than does that with a right-angled window edge.
