Zone-plate-array Lithography (zpal)
Nanolithography is the key technology driving technological progress in electronics, photonics, information technology and biotechnology. The tools and techniques used in the semiconductor industry have become too expensive for applications other than high-volume manufacturing. Masks, which are required for each unique design, can cost tens of thousands of dollars per layer. This economic const...
متن کاملPinhole Zone Plate Lens for Ultrasound Focusing
The focusing capabilities of a pinhole zone plate lens are presented and compared with those of a conventional Fresnel zone plate lens. The focusing properties are examined both experimentally and numerically. The results confirm that a pinhole zone plate lens can be an alternative to a Fresnel lens. A smooth filtering effect is created in pinhole zone plate lenses, giving rise to a reduction o...
متن کاملFractal zone plate beam based optical tweezers
We demonstrate optical manipulation with an optical beam generated by a fractral zone plate (FZP). The experimental results show that the FZP beam can simultaneously trap multiple particles positioned in different focal planes of the FZP beam, owing to the multiple foci and self-reconstruction property of the FZP beam. The FZP beam can also be used to construct three-dimensional optical tweezer...
متن کاملZone-plate-array lithography using synchrotron radiation
We present our results in the design and development of a multiple-beam x-ray pattern generator based on an array of Fresnel zone plates ~FZPs!. Exposures have been carried out using a synchrotron source at SuperACO ~France!, a PC-controlled piezoelectric scanning stage, and an array of FZPs fabricated by high resolution electron-beam lithography and reactive-ion etching of a tungsten absorber....
متن کاملPrecision fringe metrology using a Fresnel zone plate
In scanning beam interference lithography, a resist-coated substrate is scanned under phase-locked interfering beams to pattern large gratings or grids with nanometer level distortions. To achieve design goals, it is required to measure the spatial period, phase, and rotation of the interference fringes in real-time with high precision. In this article, we report the use of a Fresnel zone plate...
