Ion Beam Deposition IBD is a process of applying materials to a target through the application of an ion beam . image ion implanter schematic.png thumb Ion beam deposition setup with mass separator An ion beam deposition apparatus typically consists of an ion source, ion optics and the deposition target. Optionally a mass analyzer can be incorporated. In the ion source source materials in the form of a gas, an evaporated solid, or a solution liquid are ionized using. For atomic ion IBD electron ionization , field ionization Penning ion source or cathodic arc sources are employed. The later one is used particularly for carbon ion deposition. Molecular ion beam deposition employes electrospray ionization or MALDI sources. The ions are then accelerated, focused or deflected using high voltages or magnetic fields. Optional deceleration at the substrate can be employed to define the deposition energy. This energy usually ranges from a few Electronvolt eV up to a few keV. At low energy molecular ion beams are deposited intact soft landing At a high deposition energy a molecular ion fragments, while atomic ions penetrate further into the material, a process known as ion implantation . Ion optics such as radio frequency quadrupoles can be mass selective. In IBD they are used to select a single, or a range of ion species for deposition in order to avoid contamination. In particular for organic materials, this process is often monitored by a mass spectrometer . The ion beam current, which is quantitative measure for the deposited amount of material, can be monitored during the deposition process. Switching of the selected mass range can be used to define a stoichiometry .

refimprove date January 2012 Merge to Thin film date January 2011 The Chemical bath deposition CBD method is one of the cheapest methods to deposit thin film s and nanomaterials , as it does not depend on expensive equipment and is a scalable technique that can be employed for large area batch processing or continuous deposition. In 1933 Bruckman deposited Lead II sulfide PbS thin film by chemical bath deposition CBD or solution grown method. ref Chemical Bath Bruckman ref Advantages and disadvantages The major advantage of CBD is that it requires only solution containers and substrate mounting devices. The one drawback of this method is the wastage of solution after every deposition. Among various deposition techniques, chemical bath deposition yields stable, adherent, uniform and hard films with good reproducibility by a relatively simple process. The chemical bath deposition method is one of the suitable methods for preparing highly efficient thin films in a simple manner. The growth of thin films strongly depends on growth conditions, such as duration of deposition, composition and temperature of the solution, and topographical and chemical nature of the substrate. Reaction Mechanism The chemical bath deposition involves two steps, nucleation and particle growth, and is based on the formation of a solid phase from a solution. In the chemical bath deposition procedure, the substrate is immersed in an aqueous solution containing the precursors.

Ion beam assisted deposition or IBAD or IAD not to be confused with ion beam induced deposition , IBID is a materials engineering technique which combines ion implantation with simultaneous sputter deposition sputtering or another physical vapor deposition technique. Besides providing independent control of parameters such as ion energy , temperature and arrival rate of atomic Chemical species species during deposition, this technique is especially useful to create a gradual transition between the Substrate materials science substrate material and the deposited film, and for depositing films with less built in Deformation mechanics Strain strain than is possible by other techniques. These two properties can result in films with a much more durable Chemical bond bond to the substrate.

The technique aims to eliminate fixed costs of production and reduce the amount of materials used. Uses Anything that is produced using traditional printing techniques is a candidate for ink jet material deposition. In addition, the precision available with ink jet technology may be required for some industrial applications. Examples include Organic light emitting diode display production. Printed circuit board s are typically produced using Screen printing screen printing , which is not cost effective for prototyping or small production runs. Conductive ink can be used to create circuit traces. Advantages Since the underlying technology is digital, startup costs of production are relatively low. Each copy produced may be different from the last. Expensive materials may be used more efficiently no material is wasted by placing it where it doesn t need to go. Disadvantages The material to be jetted must be compatible with the print head used and must have its viscosity within a specific range.

FDM works on an additive principle by laying down material in layers. A plastic filament or metal wire is unwound from a coil and supplies material to an extrusion nozzle which can turn the flow on and off. The nozzle is heated to melt the material and can be moved in both horizontal and vertical directions by a numerically controlled mechanism, directly controlled by a computer aided manufacturing CAM software package. The model or part is produced by extruding small beads of thermoplastic material to form layers as the material hardens immediately after extrusion from the nozzle. Stepper motors or servo motors are typically employed to move the extrusion head. The technology was developed by S. Scott Crump in the late 1980s and was commercialized in 1990 ref http rpworld.net cms index.php additive manufacturing rp rapid prototyping fdm fused deposition modeling .html ref .
