  2. Spin coating - Wikipedia

    en.wikipedia.org/wiki/Spin_coating

    Laurell Technologies WS-400 spin coater used to apply photoresist to the surface of a silicon wafer. Spin coating is a procedure used to deposit uniform thin films onto flat substrates. Usually a small amount of coating material in liquid form is applied on the center of the substrate, which is either spinning at low speed or not spinning at all.

    en.wikipedia.org/wiki/Layer_by_layer

    For example, a whole car has been coated with spray assembly, optically transparent films have been prepared with spin assembly, etc. [1] Characterization of LbL film deposition is typically done by optical techniques such as dual polarisation interferometry or ellipsometry or mechanical techniques such as quartz crystal microbalance. [citation ...

    en.wikipedia.org/wiki/Chemistry_of_photolithography

    There are four basic parameters that are involved in spin coating: solution viscosity, solid content (density), angular speed, and spin time. [13] A range of thicknesses can be achieved by spin coating. Most commonly the thicknesses range from 1-200 μm. The main properties that affect the thickness of the film are viscosity and spin speed.

  5. Thin film - Wikipedia

    en.wikipedia.org/wiki/Thin_film

    Dip coating is similar to spin coating in that a liquid precursor or sol-gel precursor is deposited on a substrate, but in this case the substrate is completely submerged in the solution and then withdrawn under controlled conditions. By controlling the withdrawal speed, the evaporation conditions (principally the humidity, temperature) and the ...

    en.wikipedia.org/wiki/Sol–gel_process

    The precursor sol can be either deposited on a substrate to form a film (e.g., by dip-coating or spin coating), cast into a suitable container with the desired shape (e.g., to obtain monolithic ceramics, glasses, fibers, membranes, aerogels), or used to synthesize powders (e.g., microspheres, nanospheres).
