Abstract:
A method of operating a charged particle microscope comprising: Providing a specimen on a specimen holder; Using a source to produce a beam of charged particles, and irradiating the specimen with said beam; Using a detector to detect X-ray radiation emanating from the specimen in response to said irradiation, and to produce a spectrum comprising X-ray characteristic peaks on a Bremsstrahlung background, comprising the following additional steps:  Using an elemental decomposition algorithm to analyze the characteristic peaks in said spectrum, thereby determining a reference group of major chemical elements contributing to the spectrum; Calculating an average atomic number for said reference group, and using this in a predictive model to generate a calculated Bremsstrahlung profile for the reference group; Fitting said calculated Bremsstrahlung profile to the Bremsstrahlung background in said spectrum, and attributing a discrepancy between the latter and the former to a residual element absent from, or incorrectly quantified in, said reference group.

Claim (Index 6):
A charged particle microscope comprising:\n a source, for producing a beam of charged particles, and directing the beam of charged particles onto said specimen; a detector for detecting X-ray radiation emanating from the specimen in response to said irradiation, and, in response, to produce a spectrum comprising X-ray characteristic peaks on a Bremsstrahlung background; a controller for controlling at least some operational aspects of the microscope, said controller configured to: use an elemental decomposition algorithm to analyze the characteristic peaks in said spectrum; determine based on the characteristic peaks in said spectrum, a reference group of major chemical elements contributing to the spectrum; calculate an average atomic number for said reference group; generate, with a predictive model, a calculated Bremsstrahlung profile for the reference group; fit said calculated Bremsstrahlung profile to the Bremsstrahlung background in said spectrum and attribute a discrepancy between the Bremsstrahlung profile and the Bremsstrahlung background to a residual element absent from, or incorrectly quantified in, said reference group.
