MICRO | NANO | MEMS SHOW PREVIEW
on behalf of interposer. The company offers technology to produce semiconductor components via suitable print methods and conductive Nano ink. The company’s DA method of printing
functional structures applied directly to a wiring layer on the surface of a device allows electrical contact to the next component. The connections between the chips to be stacked are printed on the finished wafer or on the individual component (chip) in the form of a multilayered sequence. A printed interposer is known to be much more flexible and easier to produce than the currently used Si interposer. It can also be used for applications that were not previously possible with the existing technologies. Burnett has been working in the
semiconductor, micro and nanotechnology fields for around 30 years and has in that time built up a huge range of experience working for large companies and then forming his own. A practical guide to laser manufacturing will be the focus of a presentation being given by Managing Director of Laser Micromachining, Nadeem Rizvi. This talk will offer a basic introduction to the options available when using laser manufacturing methods for micro-product development and production. Practical guidance will be offered showing the results which can and can't be achieved with laser machining techniques, including videos and pictures of typical examples. Rizvi holds a Ph.D. from Imperial College London in laser physics and has worked in the fields of lasers and laser applications for over 25 years.
PIEZO POSITIONERS Equipment for manufacturing or testing on the micro and nano scale often requires something to be moved or aligned on this same scale. With over four decades of experience in research, design and manufacturing, Physik Instrumente’s lead technical consultant, Geraint Green will be sharing an inside view on piezo positioners, one of the technologies capable of nanometre level movements. Many traditional technologies are capable of getting down to the micron level movements needed for traditional manufacturing. Driving a platform using a motor attached to a screw is a technology which has been refined over the years to a point where maybe 10nm or occasionally even 5nm resolution is possible. This motor technology is unlikely to ever achieve sub 5nm accuracy due to friction/stiction inherent within this approach. To improve on this and expand on what has been learnt, we need to use systems with less friction that are not affected by the ambiance or the environment in which it is sited. Air bearings driven by electromagnetic linear motors are one option, but another far more accurate, reliable and cost effective solution are piezo stages.

Piezo technology is a material that expands when a voltage is applied and in reverse, can produce energy when under compression. In this session PI will look at the strengths and weaknesses of piezo electric positioners for movement and as a sensor, at the nanometre level. Mr Green has over 20 years experience in the sector of precision engineering, as well as spending a number of years studying underwater acoustics at the National Physics Laboratory in London.
PHOTONICS A talk on next generation photonics and nanotechnology will be given by Tom Carr, Business Development Manager from the Zepler Institute at the University of Southampton. This presentation will describe the cutting edge research being undertaken at the Zepler Institute. The Institute comprises over 300 researchers and is one of the largest research centres in its field in Europe. It is part of a number of programmes funded by the UK and EU. The talk will outline how industry can access the expertise available within the institute and the various mechanisms available– for example both the UK and EU fund programmes in the Zepler Institute to support industrial research collaborations. Carr is responsible for industrial research
collaborations, joint research proposals, and IP management. He has an MSci in Natural Sciences from the University of Cambridge and has been working in the Zepler Institute for three years. A matrix multi-touch hardware for haptics, for a natural ‘touch & feel’ human - machine interface will be the topic of discussion in a presentation being given by Jon Stark from Peratech Holdco. The company specialises in Quantum Tunneling Composite or QTC inks and has launched a new range of services to help technology customers in the smart home, Internet of Things, and consumer electronics markets utilise its unique force-sensing technology to innovate the next generation of human-machine interfaces (HMI). Allan James, Founder and CEO of Semefab
will give a talk on ‘How to engage with a multi-disciplinary MEMS fabrication facility’. Discussion will focus on case studies and the panoply of issues that form the basis for engagement with a MEMS foundry facility. A successful outcome is always a pre-requisite but is keenly dependent on the quality of information and level of technical engagement by the end customer. Key commercial aspects and pitfalls will be illustrated. Semefab has 30 years of engagement with
the electronics sector as a commercial foundry, operating three wafer fabs on a single site in Gelnrothes. Thin and smart technology will be the focus of
a talk being given by Dr Fanya Ismail, Managing Director of Sol-Gel Tech Centre. This overview will explore the latest sol-gel technology and its applications including automotive, energy, healthcare, construction, electronics and also in other scientific research fields. Spaces for each talk at the conference are
limited so reserve your place today:
