IMEC launches nanotechnology programme
In the first phase of research, the potential of semiconducting wires will be studied. IMECÕs fabrication process for making these vertical-pillar structures is now sufficiently mature to start evaluating their use in back-end-of-line (BEOL) processing, in particular as vias between metal layers. The typical dimensions of the pillars (20nm to 100nm) match perfectly state-of-the-art optical lithography. IMEC believes that this gives an ideal link between evolutionary and revolutionary technologies. Applications may be possible in both optical and switching components.
Next, the research will investigate the growth of carbon nanotubes. A main roadblock in this area is "chirality", or the variation in diameter and structure of the tubes. A third key area of research will focus on spintronics, or electron spin. Electron spin is a viable candidate for replacing the role of electron charge, as spin effects can be robust. The IIAP will identify roadblocks and explore opportunities of implementing spintronics in combination with silicon technology.
To support this research, the programme will develop metrology guidelines and provide theoretical quantitative models to describe newly observed phenomena in nanoelectronics. This will help researchers understand matter at the nanometric scale. IMEC believes that combined theoretical, modelling and experimental work is fundamental to addressing nanoelectronic challenges.
