Direct laser deposition within post process machining characterization
ICALEO 2009: 28th International Congress on Laser Materials Processing, Laser Microprocessing and Nanomanufacturing, 2009Industry applications of Direct Laser Deposition (DLD) technique grows from year to year. However, progress is limited by applications area, because most of the deposited layer still requires a post machining process (2-step). Machining can be done at the same laser workstation saving machining time. However, the laser optics are very sensitive to dust,

1989
Since the recent discovery of materials that exhibit superconductivity above 90K, there has been much interest in the preparation of thin films and coatings of these materials for numerous electronic applications. To date, most of the effort in thin film preparation has centered on physical vapor deposition techniques.

Post-deposition processing and oxygen content of TiO2-based capacitors
Microelectronic Engineering, 2011Properties of TiO"2-based capacitors with RuO"2 bottom electrode were examined. It is shown that post-deposition room temperature plasma treatment and oxygen annealing at 300^oC significantly reduces amount of impurities in the TiO"2 layer. Leakage current density of the capacitors is suppressed due to improvement of oxygen stoichiometry and increase ...

Effect of Post-Deposition Processing on ZnO Thin Films and Devices
Journal of Electronic Materials, 2009Post-deposition processing was conducted on ZnO thin films deposited by radio␣frequency (RF) magnetron sputtering. Rapid thermal annealing (RTA) and ion implantation followed by RTA gave increased conductivity and the latter increased Hall-effect mobility from 1.7 cm2 V−1 s−1 to 9.5 cm2 V−1 s−1 Metal–semiconductor–metal photodetectors (MSM-PDs) had a ...

Post-Processing of Pulsed Laser-Deposited Pzt Thin Films
MRS Proceedings, 1991AbstractPZT thin films were prepared by pulsed laser deposition on unheated Ptcoated Si substrates. As deposited, the films were amorphous. Films crystallized at 550 - 600 °C to produce predominantly crystalline ferroelectric PZT. Crystallization of the amorphous material was accompanied by a linear shrinkage of ∼2 %, as manifested in development of ...

Optimization of vapor post-deposition processing for evaporated CdS/CdTe solar cells
Progress in Photovoltaics: Research and Applications, 1999The effects of thermal annealing in conjunction with CdCl2 vapor heat treatment on the properties of CdTe/CdS thin films and devices deposited by physical vapor deposition are reported. Results are compared for three treatment variations: high-temperature anneal only, high-temperature anneal followed by CdCl2 vapor heat treatment and CdCl2 vapor heat ...

Sandy tsunami deposits are essential stratigraphic markers to document the impact of tsunamis in the geologic record. Tsunami sands are also the only record of past tsunamis that can be interrogated to retrieve quantitative information about the causative tsunami event.

IC Post-Processing Module for Deposition of Thin Metal Films
1998The postprocessing module described in this paper enables the addition of a wide range of desired metal film, while maintaining compatibility with IC processing. When being able to combine any thin metal film with electronics, a new class of transducers becomes feasible with a performance often superior to existing silicon transducers.
