Abstract:
In order to limit the negative effect of metal contamination on reflectivity within an EUV lithography device, a reflective optical element is proposed for the extreme ultraviolet and soft X-ray wavelength range with a reflective surface with an uppermost layer, in which the uppermost layer comprises one or more organic silicon compounds with a carbon-silicon and/or silicon-oxygen bond.

PCT No. PCT/BE93/00046 Sec. 371 Date Jun. 27, 1994 Sec. 102(e) Date Jun. 27, 1994 PCT Filed Jul. 1, 1993 PCT Pub. No. WO94/01808 PCT Pub. Date Jan. 20, 1994.The system comprises a latent image detection device comprising an alignment device which uses non-actinic radiation (10) and which is intended for aligning the mask pattern with respect to the substrate (3) and is designed for detecting the measure of coincidence of a mask alignment feature and a substrate alignment feature (8). The alignment device is provided with a radiation-sensitive detection system (6) which is connected to an electronic signal circuit in which the amplitude of the radiation incident on the detection system is determined, which originates from a latent image, formed in the photosensitive layer, of a mask feature, in which a spatial frequency occurs which is approximately equal to the useful resolving power of the projection lens system and considerably greater than the resolving power of the alignment device.

Abstract:
PROBLEM TO BE SOLVED: To provide an excellent method and system for determining lithography process conditions.SOLUTION: Disclosed are method and system that determine the lithography process conditions for lithography process. After input is acquired, first optimization as to illumination light source characteristics and mask design is carried out under conditions in which a non-rectangular sub resolution assist characteristic part is allowed. Then the mask design is optimized in one or more additional optimizations in which only a rectangular sub resolution assist characteristic part is allowed. Consequently, an excellent lithographic process is obtained and complexity of the mask design is limited.
Abstract:
Methods and apparatus for producing irradiation targets in an extreme ultraviolet (EUV) light source having an irradiation target generating system that includes a nozzle configured for ejecting droplets of a target material, and a subsystem having an electro-actuable element producing a modulation waveform to cause disturbance to the droplets thereby causing at least some of the droplets to coalesce into irradiation targets. There is included a laser producing a beam for irradiating the irradiation targets to generate an EUV-producing plasma, wherein the electro-actuable element is biased against the nozzle to enable transfer of the disturbance to the droplets while permitting relative movement between the electro-actuable element and the nozzle.
