DESCRIPTION

Optical ellipsometry is a non-destructive technique for investigation of surfaces, interfaces and thin films. It probes modifications of the polarization state of optical beam reflected from the sample. The system provides ellipsometric analysis with the lateral resolution of 1 μm. Optical illumination of the sample takes place via monochromatic radiation (spectrally filtered light from Xenon Arc lamp with the bandwidth of 6 - 12 nm) with tunable wavelength in the range from 365 nm (UV) to 1600 nm (NIR). Extension to the NIR region is a specialty of our system that makes it very suitable for investigations of semiconductor materials. Laser light source at λ = 658 nm can also be used for illumination and polarization analysis.

DESCRIPTION

DaLI is a desktop laser imaging system for mask-less photolithography and patterning. The system uses direct exposure with an UV diode laser beam (375 nm) to pattern materials sensitive to ultraviolet light. Standard i-line photoresists, such as SU-8, AZ, etc. can be used. Exchangeable exposure tool sizes (beam diameters) provide high precision details and speed (fine 0.8um, coarse 2.5um). The flexibility of this technology enables design changes and experimentation, which makes the DaLI perfect for R&D and prototyping. Conducting, isolating, semiconducting, transparent or opaque substrate can be used; max. lateral dimensions 100 mm x 100 mm, maximum thickness 10 mm.

DaLI is used in the field of micro-scale technology, microfluidics and optofluidics, nanotechnology, microelectronics, and enables microstructuring a variety of micro devices, such as integrated circuits, PCBs, MEMS, lab-on-a-chip, and other applications.
