Abstract:
The disclosure provides a projection exposure method for exposing a substrate arranged in the region of an image plane of a projection lens with at least one image of a pattern of a mask arranged in the region of an object plane of the projection lens. A substrate is coated with a radiation-sensitive multilayer system including a first photoresist layer composed of a first photoresist material and, between the first photoresist layer and the substrate and a separately applied second photoresist layer composed of a second photoresist material. The first photoresist material has a relatively high first sensitivity in a first wavelength range and a second sensitivity, which is lower relative to the first sensitivity, in a second wavelength range separate from the first wavelength range. The second photoresist material has an exposure-suitable second sensitivity in the second wavelength range.

Claim (Index 16):
A projection exposure apparatus configured to expose a substrate arranged in a region of an image plane of a projection lens with at least one image of a pattern of a mask arranged in a region of an object plane of the projection lens, the projection exposure apparatus comprising:\n a primary radiation source configured to emit radiation in an operating wavelength range comprising a first wavelength range and a second wavelength range separate from the first wavelength range; an illumination system configured to receive the radiation and to generate an illumination radiation directed onto the mask; a projection lens configured to generate an image of the pattern in the region of the image surface of the projection lens, wherein:\n the projection exposure apparatus is configured so that the projection lens is corrected at least for the first wavelength range and the second wavelength range so that with each wavelength in the first and second wavelength ranges a sharp diffraction-limited imaging of the pattern onto the substrate is possible with an identical imaging scale; and \n a first focus region associated with the first wavelength range is offset relative to a second focus region associated with the second wavelength range by a focal distance.
