Opportunities for highest-fidelity micromanufacture towards unprecedented large-scale integration of bioanalytical "Lab-on-a-Chip" systems


This presentation shows up the tremendous synergies situated at the exciting crossroads of highest accuracy and precision tooling and replication, digital twin concepts, and an NFT-based research metaverse enabled by blockchain for leveraging order-of-magnitude improvements in the functional integration density of multivariate, high-performance, microfluidic systems. Along the digital twin model for developing exemplary centrifugal microfluidic "Lab-on-a-Disc" systems, it will turn out that the decisive functional integration density is mostly linked to feature miniaturization and manufacturing quality. Drawing striking parallels to Moore's law and microelectronics, this feasibility study will quantitate the technological requirements for passing challenging technological frontiers, and then sketch next-generation applications, primarily in medical diagnostics and the life sciences. These fields are decisively driven by AI, which needs to be trained by comprehensive, multivariate, population-scale databases. These can be efficiently filled by the proposed technology, for the eventual benefit of patients, economies and societies.

Review of Atomic Force Microscopy based metrology & manipulation at the nanoscale


Today, a wide range Atomic Force Microscopy (AFM) based characterisation methods are routinely applied in nanoscale studies of electronic materials and devices. The standard capability of AFM to image the surface topography with nanometre scale spatial resolution is augmented with the capability to measure a variety of physical properties: electrical (for example, surface potential, work function, conductivity, carrier density), magnetic, thermal (temperature distribution, thermal conductivity), mechanical, and more recently also chemical. Furthermore, several AFM as well as STM modes exist to manipulate and modify materials at the nanoscale, often based upon specific electrical, mechanical, optical or chemical interactions.  We will cover a structured overview of these operating modes presenting their capabilities and limitations with case studies.

Digital Transition in Manufacturing of Porous and Lattice Structures


The digital transition in manufacturing has brought about significant advancements in the production of porous and lattice structures, both and periodic and stochastic ones. This work focuses on exploring the impact of digital technologies on the design and production processes of these complex structures. Digital tools such as computer-aided design (CAD) software and simulation techniques have revolutionized the design phase, enabling engineers to create intricate and customized geometries for porous and lattice structures. Through simulation tools like finite element analysis (FEA) and computational fluid dynamics (CFD), designers can evaluate structural integrity, fluid flow dynamics, and heat transfer characteristics, leading to optimized designs. Additive manufacturing plays a crucial role in the digital transition of porous and lattice structures. It allows for the precise fabrication of complex geometries, offering design freedom and customization possibilities that were once unattainable with traditional manufacturing methods. The digital transition also facilitates design optimization, where advanced algorithms and computational models aid in exploring optimal material configurations, pore sizes, and connectivity to achieve desired mechanical, thermal, and fluid transport properties. While the digital transition presents exciting opportunities, challenges such as design complexity, material selection, and process optimization need to be addressed. Overcoming these challenges will contribute to the efficient production of tailored porous and lattice structures with enhanced performance and functionality. This work highlights the advancements and challenges associated with the digital transition, emphasizing the potential for improved designs, customized structures, and enhanced performance in various industries.

The Biological Transformation in Manufacturing: Current Trend and Future Development


This presentation reports on a very ambitious international study carried out in the period 2018 - 2022 on the topic of the convergence between biology (the biosphere) and manufacturing engineering (the technosphere). Four demonstrators from different sectors of the manufacturing value chain and involving bio-inspiration, bio-integration and bio-intelligence were selected to test the following hypothesis: “Future Manufacturing Systems will incorporate Components, Features, Characteristics and Capabilities that enable the convergence towards Living Systems”. Each of the four demonstrators have succeeded in supporting this hypothesis and in providing clear evidence to confirm that significant performance benefits may be derived through the “biologicalisation” of advanced manufacturing engineering. The evidence reported provides a robust basis for recommending that a deeper analysis of the implications of biologicalised manufacturing technology and systems be undertaken. As a result of this initial work, it can be concluded that there is a high likelihood that this new convergence will lead to a major paradigm shift in advanced manufacturing. Existing industries will change and new industries will form and, as a result, outstanding opportunities exist for high levels of innovation in the next stages of development of advanced manufacturing technology and systems from the biological perspective

Surface Reaction Kinetics for Inherent Selective Atomic Layer Deposition


With the development of Atomic and Close-to-atomic Scale Manufacturing(ACSM), the chemical principal and mechanisms that enable selective atomic layer deposition (ASD) is gaining rapid growing interests to unlock attractive avenues for the development of novel nanostructures by depositing atoms at desired surface locations. It has found versatile applications in emerging fields beyond semiconductor industry. Yet with the continuing downscaling, it is important to expand approaches for selective ALD with atomic scale precision on nanoscale features. In this talk, the inherently selective atomic layer deposition processes will be discussed. Previously, we have demonstrated facet-selective ALD processes, which based on intrinsic differences of precursors chemisorption on terraces or step edges of nanoparticles. To expand the inherently ASD, the acidity and alkaline, surface electronegativity, lattice strains could be exploited to achieve this inhibitor-free selective deposition process. It is demonstrated that the electronegativity differences altering the chemisorption energy barrier, which affects the initial nucleation rate. Oxides ALD was studied on a series of oxide substrates. Although the oxides have -OH groups on the surface and proposed to have similar nucleation sites, there are long nucleation delays on basic oxides. The H-transfer reaction is a key factor to influence the reaction barrier. It is hard to nucleate on basic substrates because the H-transfer reaction is blocked. In addition, an anisotropic growth model with the dynamical competition of expansion and dissociation of the nucleus is proposed to nucleation delay are quantitively predicted and the model provides a practical method to evaluate the selectivity of ALD theoretically. It provides a new strategy for inherently selective ALD, which will expand the selective toolbox of nanofabrication for next-generation nanoelectronic applications.

Advanced 3D optical metrology of Freeforms


Characterisation of Freeforms are increasingly demanded by optical manufacturers and users and are always challenging topic for metrologists. The metrologist now has both advanced contact and non-contact measurement solutions available and a combination of these techniques to provide more detailed understanding of opical components.

Form errors of the freeform surfaces resulting from the manufacturing process are critical, in terms of the functionality and reliability of the freeform optics. This presentation will introduce two advanced Freeform measurement techniques, a 3D contact profilometry and a 3D non-contact scanning point interferometry. The contact method is accomplished by use of an ultra-low noise measurement platform, combined with a patented phase grating interferometry (PGI) technology and specially developed algorithms for calibration and analysis. The high slope measurement capability of PGI Freeform, together with its large gauge range, enables 3D form measurements for most freeform surfaces.  Non-contact scanning metrology is based on a patented multi-wavelength interferometry (MWLI) technology. It provides high density 3D data in short measurement times at a highly reproducible form measurement accuracy. The long-range absolute measurement capability of the MWLI sensor, together with its ultra-precision metrology platform and improved calibration routine through which the sensor accurately follows the designed shape of optical surfaces, enables precise 3D freeform surface measurements within its tangential slope measurement range.


Dr. Yang Yu received her BSC degree in Precision Engineering at Tianjin University, China, and completed her MSc and her PhD in Material Physics at Loughborough University, UK. She is currently working at the headquarter of Taylor Hobson Ltd. in UK, operating globally as a Senior Applications Scientist/Manager in the field of Optic metrology, including contact and non-contact metrologies.

Advanced alignment turning of mounted spherical and aspherical optics


The performance of modern optical systems is dominantly determined by the precision of the alignment of single lens elements in the optical path of the system. The highest alignment precision as well as leading productivity in fabrication can be achieved by alignment turning. A lens to be assembled is glued into a metal mount not considering precision orientation yet. The lens and mount are introduced to an alignment turning machine to measure the optical axis and to correct the metal mount by slow tool turning in a way that the optical and mechanical axis have the same orientation after machining. Remaining shifts of down to 1 micron and tilts < 10 arcsec can be achieved within minutes. As the glue has been solidified prior to machining, there are no more subsequent displacements. The new machine system to be presented is the world leading platform for flexible alignment turning of various types of optics. With its latest sensors, it is capable of measuring IR optics with a 4.05 µm laser system. In addition, aspherical lenses can be characterized in their orientation by a full aperture confocal scan. Full automation applies to the measuring steps, the slow tool machine program calculation as well as subsequent quality assurance steps. Current tests on objectives with aspheric lenses have led to an overall optical system improvement of > 30% at significantly reduced assembly times. The presentation covers an introduction to the technology and the machines as well as sample machining results.


Dr. Christian Wenzel studied mechanical engineering at the Aachen University of Technology (RWTH) with a focus on production technology. Subsequently he joined the Fraunhofer Institute of Production Technology IPT to achieve a PHD degree in the field of corrective polishing of precision optical elements. He continued as head of department for ultra precision machine tools, micro-assembly and machine characterization at the institute. In 2009 he founded the Innolite GmbH with a focus on the commercialization of diamond machining and the development of advanced multi axes ultra precision machine tools. With over 50 employees and a subsidiary in Shanghai China the company is developing in mechanics, control systems, in line metrology and software.
