Abstract: The invention concerns an irradiation device for testing objects coated with light-sensitive paint, comprising a EUV radiation source, an optical system for filtering the radiation of the EUV radiation source a chamber for receiving the object, as well as systems for intersecting the trajectory of the rays on the object. The invention also concerns a method for operating such a device. The invention aims at obtaining as quickly as possible an illumination at least partly simultaneous of several irradiation fields, with different doses, by using an inexpensive laboratory radiation source without resorting to complex optical systems. Therefor, the invention provides a device comprising a simplified and compact optical system, with closable diaphragm apertures located in front of the object to be irradiated and at least one control sensor placed on the trajectory of the rays and enabling the radiation dose to be measured.

Abstract: Outgassing products, which are formed during the exposure of photoresist systems by laser irradiation, are adsorbed on a proof plate for further analysis.

Abstract: A method for forming a lithography mask on a surface region of a wafer is presented. In one embodiment of the method according to the invention time periods from the end of an exposure operation until the beginning of a thermal aftertreatment for the sections of the semiconductor material region are to be identical or approximately identical.

Abstract: The outgassing products, which are formed when photoresist systems, are exposed to laser radiation are verified by a mass spectrometer connected to the irradiation chamber.

Abstract: Based upon an existing or to be produced multi-layered semiconductor-insulator-semiconductor carrier layer wafer (SOI substrate), irregularity of the etching conditions between the center and the edge region occurring during dry etching can be counteracted by a number of alternative steps, in particular, an additional layer construction compensating for the etching irregularity so that in any event an approximately homogeneous etching removal takes place over the entire area of the wafer to be etched.
