  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.

  3. Chemistry of photolithography - Wikipedia

    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.

  4. Layer by layer - Wikipedia

    en.wikipedia.org/wiki/Layer_by_layer

    The bilayers and wash steps can be performed in many different ways including dip coating, spin-coating, spray-coating, flow based techniques and electro-magnetic techniques. [1] The preparation method distinctly impacts the properties of the resultant films, allowing various applications to be realized. [ 1 ]

  5. Self-cleaning glass - Wikipedia

    en.wikipedia.org/wiki/Self-cleaning_glass

    The first self-cleaning glass was based on a thin film titania coating. [3] The film can be applied by spin coating of organo-titanate chelated precursor (for example titanium iso-tetrapropoxide chelated by acetylacetone), followed by heat treatment at elevated temperatures to burn the organic residues and to form the anatase phase.

  6. Slot-die coating - Wikipedia

    en.wikipedia.org/wiki/Slot-die_coating

    A schematic of a typical slot-die coating system. Slot-die coating equipment is available in a variety of configurations and form factors. However, the vast majority of slot-die processes are driven by a similar set of common core components. These include: A fluid reservoir to store the main supply of coating fluid for the system; A pump to ...

  8. Drawdown chart - Wikipedia

    en.wikipedia.org/wiki/Drawdown_chart

    Initially the desired coating is applied in a puddle on the drawdown chart. Then the bar is placed at the top of the chart, and drawn down over the paint in order to spread it evenly along the length of the chart. Once this evenly spread paint dries, it can be tested for a variety of properties. [5]
