Product/Research Description

Most integrated circuits are produced by transferring an Image, by optical lithography from a photomask to silicon. High resolution patterns can be produced in Si/Ge layers. We have demonstrated, in collaboration with Compugraphics International, that such photomasks can be used successfully to transfer high resolution Images. Fine line writing for advanced photomasks has also been pioneered together with the Physical Chemistry Group. As integrated circuits continue to increase in complexity there is a growing need for new techniques to produce high resolution conductive metal tracks in a simple reproducible process. We have synthesised a new range of organometalic compounds with gold, palladium and copper which can be spin coated on glass where subsequent electron bombardment produces sub-micron metal tracks.

Dundee has pioneered much of the work on amorphous silicon and continues to stay at the forefront of research. New research areas include display materials, non-volatile memory devices, quantised transport devices, quantum well laser capping and intermixing technology, novel diffraction techniques for high stability solar cells and large area optical and x-ray sensors. Our work on medical snesors may offer a replacement device for radiology offering low dose, real time x-ray imaging.

Specialised Skills and Facilities

Facilities within the group include three PECVD reactors for deposition of Intrinsic and doped silicon and its alloys, housed within a purpose built clean room, photo-thermal deflection spectroscopy, transient photoconductivity, capacitance – voltage, spectrophotometry, FTIR, ESR etc. The Group has four members of academic staff, two research associates, six PhD students. The AMRG has enjoyed a long history of collaboration with Industry and universities across the world, including Xerox, Philips, British Telecom, British Petroleum and Zeneca. The international reputation of the group has allowed the running of a successful MSc course in Materials for Displays and Sensors. The course, for students with a background in physics or Electronic Engineering includes detailed sections on Displays, Imaging, Image Processing, Materials Processing, Amorphous Semiconductors, Electronic, Optical and Magnetic Properties of the Thin Film Devices, Electron Beam Micro-analysis, Sensors and large area detectors together with laboratory and project work. Both groups are supported by and work with an electron microscopy and surface micro-analysis group that have facilities such as SEM, TEM, XPS, EDX, EELs, Auger electron spectroscopy, SIMS EBIC etc. Together the Microelectronics Materials Division has fourteen members of academic staff, ten research associates, and many post-graduates students.
