Abstract: Systems and techniques involving optical coatings for semiconductor devices. An implementation includes a substantially isotropic, heterogeneous anti-reflective coating having a substantially equal thickness normal to any portion of a substrate independent of the orientation of the portion.

Abstract: An optically tuned SLAM (Sacrificial Light-Absorbing Material) may be used in a via-first dual damascene patterning process to facilitate removal of the SLAM. The monomers used to produce the optically tuned SLAM may be modified to place an optically sensitive structure in the backbone of the SLAM polymer. The wafer may be exposed to a wavelength to which the SLAM is tuned prior to etching and/or ashing steps to degrade the optically tuned SLAM and facilitate removal.

Abstract: An apparatus and method for forming catalyst particles to grow nanotubes is disclosed. In addition, an apparatus and method for forming nanotubes using the catalytic particles is also disclosed. The particles formed may have different diameters depending upon how they are formed. Once formed, the particles are deposited on a substrate. Once deposited, the mobility of the particles is restricted and nanotubes and/or nanotube portions are grown on the particles. Nanotube portions having different diameters may be formed and the portions may be connected to form nanotubes with different diameters along the length of the nanotube.

Abstract: This invention consists of two parallax barriers (1,2) of which at least one is activated electronically (3), forming a single device (D), which is placed between the image display system (4) and the observer (001) at sufficient distance (x) from the latter so as not to bother him/her and through which, with no need for glasses or any other device before the observer's eyes and allowing the observer to move his/her head freely, he/she will be able to see with his/her left eye the image (I1) corresponding to that eye and with his/her right eye the image (I2) corresponding to that eye, these images (I2, I2) being displayed using polarised light and in polarisation planes perpendicular to each other (4) or time-multiplexed.

Abstract: The optical system comprises a convergent mirror (Ec) and a plane mirror (Ep), which are duly positioned in order for the focus (F) established in the optical axis (X—X) of the convergent mirror (Ec) in turn to be located in the sector lying between both mirrors. An object (I1-I2) located in an area (1) is first reflected onto the plane mirror (Ep) and then onto the convergent mirror (Ec), yielding an image (I″1-I″2) in an area (2) opposite the area (1) in a normal position for an observer located at a point (O) outside the system, i.e. in such a position that the signs are legible.

Abstract: Process for the reproduction of three-dimensional static or moving images, in which the stills, in number greater than three, are positioned on a single film, projection is carried out in groups of stills which are projected through a single optical projection system, the optical path taken by the rays from the central still of each of these groups is not split by any lateral reflection, the remainder of the light rays from the remainder of the stills undergoes as many lateral reflections as indicated by the number of its position with respect to the central still, the stills on the film with an odd number of reflections being specularly inverted with respect to the stills which occupy even sites and the central one.
