A method for generating cut surfaces in the cornea of an eye in order to correct ametropia using an apparatus. The method includes providing the apparatus including a laser unit, which focuses pulsed laser radiation into the cornea and moves the focused radiation in the cornea to generate cut surfaces, and a control unit, which controls the laser unit for generating cut surfaces. The method includes forming at least two mutually spaced apart cut surfaces as opening cuts by application of the pulsed laser radiation from the laser unit, each opening cut extending from an anterior corneal surface into the cornea and forming a further cut surface as a relieving cut by application of the pulsed laser radiation from the laser unit, which relieving cut extends from the anterior corneal surface into the cornea. The position and shape of the relieving cut is selected such that the relieving cut contributes to the correction of the ametropia of the eye.

A probe head for a coordinate measuring machine has a first probe head part with an interface, for coupling the probe head to the coordinate measuring machine. A second probe head part is coupled to the first probe head part and is rotatable relative to the first probe head part about a first axis. A third probe head part is coupled to the second probe head part and is pivotable relative to the second probe head part about a second axis. The first and second axes lie askew in relation to each other. A first actuator pivots the third probe head part about the second axis via a push rod coupled to the third probe head part at a lateral distance from the second axis. The first actuator moves the push rod in a longitudinal direction to pivot the third probe head part relative to the second probe head part.

An imaging optical system for a projection exposure system has at least one anamorphically imaging optical element. This allows a complete illumination of an image field in a first direction with a large object-side numerical aperture in this direction, without the extent of the reticle to be imaged having to be enlarged and without a reduction in the throughput of the projection exposure system occurring.

The npSCOPE project aims at developing a new integrated instrument (the nanoparticle-scope) optimised for providing a complete physico-chemical characterisation of nanoparticles both in their pristine form or embedded in complex matrices such as biological tissues. Using sophisticated correlative data processing methodologies and algorithms based on statistical methods in conjunction with appropriate visualisation methods of the results, the npSCOPE instrument will allow rapid, accurate and reproducible measurements. The instrument will be based on the Gas Field Ion Source as a key enabling technology, which we will combine with a number of new developments in the field of electron and ion microscopy. We will progressively ramp up the TRL of the instrument and associated methodologies to reach TRL 7 by the end of the project. The new technology, and all related processes and methodologies, will be validated via round-robin studies performed independently by several partner institutions, crosschecked with conventional analysis technologies to demonstrate the advancements and capabilities of the npSCOPE technology and benchmarked in representative case studies. Given the low sample quantities needed and the strong potential of the instrument to generate high-quality physico-chemical data on nanomaterials, both ex situ and in situ, npSCOPE will allow a major step forward in defining key descriptors for read-across, grouping, in silico modelling and creating meaningful relationships with biological activity data for QSAR purposes. To reach these objectives, the project consortium will be composed of research centres internationally recognised for innovative instrument developments, well-established instrument manufacturers and experts in nanotoxicology in various fields of application to demonstrate and validate the applicability of npSCOPE for the risk assessment of nanomaterials in consumer products.

The TAKE5 project is the next in a chain of thematically connected ENIAC JU KET pilot line projects which are associated with 450mm/300mm development for the 10nm technology node and the ECSEL JU project SeNaTe aiming at the 7nm technology node. The main objective of the TAKE5 project is the demonstration of 5nm patterning in line with the industry needs and the ITRS roadmap in the Advanced Patterning Center at the imec pilot line using innovative design and technology co-optimization, layout and device architecture exploration, and comprising demonstration of a lithographic platform for EUV technology, advanced process and holistic metrology platforms and new materials. A lithography scanner will be developed based on EUV technology to achieve the 5nm module patterning specification. Metrology platforms need to be qualified for 5nm patterning of 1D, 2D and 3D geometries with the appropriate precision and accuracy. For the 5nm technology modules new materials will need to be introduced. Introduction of these new materials brings challenges for all involved deposition processes and the related equipment set. Next to new deposition processes also the interaction of the involved materials with subsequent etch steps will be studied. The project will be dedicated to find the best options for patterning. The project relates to the ECSEL work program topic Process technologies More Moore. It addresses and targets as set out in the MASP at the discovery of new Semiconductor Process, Equipment and Materials solutions for advanced CMOS processes that enable the nano-structuring of electronic devices with 5nm resolution in high-volume manufacturing and fast prototyping. The project touches the core of the continuation of Moores law which has celebrated its 50th anniversary and covers all aspects of 5nm patterning development.
