This paper presents a sample preparation study on a FIB based X-sectio
n. It shows that wet etching is a simple and reproducible solution for
the decoration of both implanted and deposited layers. The methodolog
y is applicable on bare or packaged dice. Results with EBIC on FIB cro
ss-sections were arise obtained. A specific double FIB box method was
developed and characterized to improve spatial resolution of EBIC. (C)
