Abstract
Abstract A microscope system for detecting the emission distribution of specimens which emit light at least in a punctiform manner, particularly for failure analysis of integrated circuits, comprises an imaging beam path from the specimen in the direction of an at least one-dimensional receiver distribution, wherein at least one element is provided in the imaging beam path for spectral division of the light which is emitted at least in a punctiform manner.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
128 words
A process for the operation of a microscope system having an imaging beam path from a specimen in a direction of an at least one-dimensional receiver distribution, comprising the steps of: imaging the specimen to produce a light output from said specimen; displaying an image representative of said light output by the specimen; marking one or more points or areas of the displayed image; providing, after marking of said one or more points or areas, within the imaging beam path an element adapted to spectral divide fight emitted at least in a punctiform manner; moving the one or more marked points or areas into a predetermined image coordinate of the displayed image; and receiving a spectrum of light resulting from the spectral division of light by said element.
Claim 2
Dependent Claim
128 words
A process for the operation of a microscope system having an imaging beam path from a specimen in a direction of an at least one-dimensional receiver distribution, comprising the steps of: imaging the specimen to produce a light output from said specimen; displaying an image representative of said light output by the specimen; marking one or more points or areas of the displayed image; providing, after marking of said one or more points or areas, within the imaging beam path an element adapted to spectral divide fight emitted at least in a punctiform manner; moving the one or more marked points or areas into a predetermined image coordinate of the displayed image; and receiving a spectrum of light resulting from the spectral division of light by said element.
Claim 3
Dependent Claim
70 words
The process for the operation of a microscope system according to claim 1, wherein the step of marking is carried out by a step of detecting emitting points or areas automatically or by marking said points or areas displayed; and the method further comprises the step of: displaying light-sensitive areas of the receiver distribution which are arranged in the dispersing direction as viewed from the marked or detected starting point.
Claim 4
Dependent Claim
17 words
The process according to claim 2, wherein the detecting step is carried out in a dispersing direction.
Claim 5
Dependent Claim
27 words
The process according to claim 2, wherein the detecting step is carried out at an angle to the direction of rows or columns of the receiver distribution.
Claim 6
Dependent Claim
41 words
The process for the operation of a microscope system according to claim 2, further comprising the step of simultaneously detecting and evaluating a plurality of emitting points or areas and their spectral distribution by controlling light-sensitive areas of the receiver distribution.
Claim 7
Dependent Claim
55 words
The process for the operation of a microscope system according to claim 2, further comprising the steps of: storing the spectral distributions in storage elements; detecting the frequency/intensity of occurrence of individual wavelengths of said spectral division stored in the storage elements; and one-to-one assigning of the spectral distributions corresponding to their detected frequency distribution.
