Patent attributes
A charged particle beam device includes an input and output device that receives, as inputs, a charged particle beam condition, a light condition, and electronic device circuit information, a charged particle beam control system that controls a charged particle beam applied to a sample based on the electron beam condition, a light control system that controls light applied to the sample based on the light condition, a detector that detects second electrons emitted from the sample by the application of the charged particle beam and the light and outputs a detection signal, and a calculator that generates a calculation netlist based on the electronic device circuit information, generates a light irradiation netlist based on the calculation netlist and the light condition, estimates a first irradiation result when the charged particle beam and the light are applied to the sample based on the light irradiation netlist and the charged particle beam condition, and compares the first irradiation result with a second irradiation result when the charged particle beam and the light are actually applied to the sample based on the electron beam condition.
