Ellipsometry measures the change in polarization as the polarized light interacts with the sample structure. The data is then analyzed to determine material properties like film thickness, optical constants, refractive index, etc. The RC2 ellipsometer is a tool with a unique capability of collecting all 16 elements of the Mueller matrix. Mueller matrix SE allows characterization of the most advanced samples and nanostructures.

WYKO NT3300
The Optical Profiler investigates variations in topography for surfaces ranging from
very smooth to 2mm step height. Basic interferometric principles are used with light
reflected from a reference mirror combined with light reflected from a sample to produce
interference fringes, where the best-contrast fringe occurs at best focus.
Two modes of interferometry are used: PSI (Phase Shifting Interferometry) mode uses variations in phase of a monochromatic (632 nm) reference source to combine with beam reflected from the sample to form interference rings. The variation in intensity of the rings at significant phases is used to calculate small height variations on the sample surface. VSI (Vertical Scanning Interferometry) mode uses short coherence length of white light to measure the resulting degree of fringe modulation, or coherence, between the reference and sample beams as the interferometric objective moves vertically through sample focus. The vertical position of the optics at peak fringe contrast is extracted for each point on the sample surface, resulting in a topographical map.

The hot plate station is comprised of four Prazitherm precision hot plates manufactured for resist processing. Each hot plate is sized 350mm x 350mm. They are flat and level, with temperature uniformity of +/- 0.5º. The maximum operating temperature is limited to 200ºC in order to maintain temperature inside the cleanroom. A hood located over the hot plate station ensures evaporated fumes are not released into the cleanroom environment.
Each hot plate is controlled through its own PID controller with a PC using iTools© software by Eurotherm. The programmable software allows for controlled and automated heating and cooling cycles, though there is no active cooling associated with the hot plates. Each controller has 4 recipes, with 16 segments available for programming each recipe.

The Heraeus vacuum oven is controlled by a Delta DTP - PID controller. The controller is optionally PC interfaced for recipe storage and remote control or continuous heating. Temperture control is ± 0.5 degrees C
