Charged particle lithography system with sensor assembly |
摘要 |
The invention relates to a charged particle lithography system for transferring a pattern onto a target, said system comprising:;a target positioning device comprising a target holder having a first side for holding the target,;a charged particle optical unit for generating a charged particle beam, modulating said charged particle beam, and directing said charged particle beam towards the first side of the target holder, and;a sensor assembly comprising a converter element for converting charged particles which impinge on said converter element into light, wherein the converter element is arranged on said target positioning device, a light sensor for detecting the light, wherein the light sensor is arranged at a distance from said target positioning device, and a light optical lens which is arranged between the converter element and the light sensor for directing light originating from said converter element to said sensor. |
