High speed mask-less laser-controlled precision micro-additive manufacture
A rapid, mask-less deposition technique for writing metal tracks has been developed. The technique was based on laser-induced chemical vapour deposition. The novelty in the technique was the usage of pulsed ultrafast lasers instead of continuous wave lasers in pyrolytic dissociation of the chemical …

Materials and processes for the optical additive manufacturing of advanced organic/inorganic nanocomposites for the mask-less plating of insulator and semiconductor substrates, and microfluidic devices
… the diffraction limit, down to 100 nm or even less. Here, this multi-photon absorption process is exploited to trigger the photo-reduction of the gold precursor. The use of a transparent hydrogel matrix allows for a fine control of the nanoparticles growth on either transparent or opaque …

Submicron patterning using laser interference lithography
… solely in means of pattern delineation. IL is a "mask less" technique that employs the interference fringe pattern of two coherent beams, and can therefore be generated with a commercial laser. Due to its simplicity, Interferometric Lithography provides an attractive supplement to existing methods …

The Mirrored Walls Of Reality:a Journal Of Shattered Reflection
… from the reflection man sees everyday and hopelessly fails to recognize. Ultimately, theatre demands that man see himself without the masks of excuse, ignorance, or makeup. It is the vision of this journey to honor theatre's mask-less demand. Through the development of a multi-scene theatrical …

Indium phosphide based integrated photonic devices for telecommunications and sensing applications
… The laser is monolithically fabricated using mask-less lithography techniques and tuning is demonstrated in Fabry-Perot cavity lasers under continuous-wave operation. A ring-coupled 2 [mu]m wavelength laser is designed that will exhibit a tuning range of tens of nanometers.

Fabrication and material characterization of silver cantilevers via direct surface micromachining
… to an X-Y microcontroller stage, we present a mask-less, or direct, surface micromachining process flow with a 250°C thermal budget. The process uses Cabot Corp.'s silver-based conductive ink for the structural layer and PMMA for the sacrificial layer. Several other materials were tested for …

APPLICATION OF TRACK ETCHED GLASS MEMBRANES FOR SUBMICRON FABRICATION, LITHOGRAPHY AND ERROR RECTIFICATION
… gradient etching in tracked glass, (ii) mask less photolithography and with tracks etched glass and (iii) polymeric microfabrication which will also be covered in detail in this dissertation

The Fabrication of Integrated Strain Sensors for “Smart” Implants using a Direct Write Additive Manufacturing Approach
… resistance strain gauge sensors using rapid and mask-less process by experimental development (design of experiment) using the nScrypt 3Dn-300 micro dispensing direct write (MDDW) system. Silver and carbon electrical resistance strain gauges were fabricated and characterised. Carbon resistive …

Inkjet Printing of 2d Materials on Flexible and Rigid Substrates
… inkjet printing technology. This strategy allows mask-less, large-area and low-cost deposition of 2d materials for next generation device fabrication. However, the current inks are far from ideal to support reproducible device manufacturing. In this thesis, I present formulation of inkjet …
