Direct Laser Lithography and Its Applications - IntechOpen- direct laser writing technique ,The direct laser lithography is a useful technique to fabricate a large precision patterns such as CGHs, DOEs, and reference wafers. The typycal lithograpic system we have built can write up to 360-mm diameter substrate coated with chromium or photoresist film. The writing source were stabilized by using the AOM, the PD, and the servo controller. Direct Laser Writing of Supercapacitors - IntechOpenDirect laser writing is a single-step fabrication technique for the micro and nanostructures even below the sub-diffraction limits. In recent times, the technique is adapted to the fabrication of on-chip energy storages with additional features of flexibility and stretchability.

A challenge for design, testing, and fabrication of nanostructured chemical sensors is the fabrication of mm 2 size arrays of nanostructures in a reasonable time. Herein, we introduce and show how direct laser writing (DLW) in positive-tone photoresists, followed by lift-off process, can be used for fast fabrication (up to three times faster than a comparable electron beam lithography system ...

Multiphoton lithography (also known as direct laser lithography or direct laser writing) of polymer templates has been known for years by the photonic crystal community. Similar to standard photolithography techniques, structuring is accomplished by illuminating negative-tone or positive-tone photoresists via light of a well-defined wavelength.

To fabricate three-dimensional photonic-crystal and metamaterial structures, we have developed and optimized a technique called direct laser writing (DLW). In DLW, femtosecond pulses are very tightly focused to a diffraction-limited optical spot. Only in the central region, the light intensity is sufficiently large to lead to significant two ...

LOPA-based direct laser writing technique. By using a standard fabrication process that already described in chapter 3, we demonstrated that LOPA-based polymerization is achieved only at the focusing spot, where the excitation intensity is strong enough to simultaneously trigger local photochemical reactions leading to polymer cross-linking during the subsequent post-exposure bake step.

Laser-based direct-writing techniques are particularly attractive for fabricating three-dimensional microstructures [4]. Indeed, depending on the laser excitation wavelength and whether or not the laser output is continuous or pulsed, lasers can be used to drive a wide range of physical and chemical processes, which are then the basis for ...

The direct laser writing technique is employed for both arbitrary patterning and surface modification. By integrating the functional layer at the desired position or by designing asymmetric structures, three typical light-driven floating devices with fast linear or rotational motions are demonstrated.
