  2. Spin coating - Wikipedia

    en.wikipedia.org/wiki/Spin_coating

    The substrate is then rotated at speeds up to 10,000 rpm to spread the coating material by centrifugal force. A machine used for spin coating is called a spin coater, or simply spinner. [1] Rotation is continued while the fluid spins off the edges of the substrate, until the desired thickness of the film is achieved.

  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. Nanosphere lithography - Wikipedia

    en.wikipedia.org/wiki/Nanosphere_lithography

    Spin Coating and solvent evaporation methods are capable of producing large areas of particles, but with limited control over the layer homogeneity or thickness. [ 3 ] Solvent evaporation is accomplished via drop coating, and is arguably the simplest method to produce a monolayer of nanospheres, as the spheres are simply dropped onto the ...

  5. Nanoparticle deposition - Wikipedia

    en.wikipedia.org/wiki/Nanoparticle_deposition

    The spin and dip coating methods are simple methods for nanoparticle deposition. [4] They are useful tools especially in creating self-assembled layers and films where the packing density isn't critical. Accurate and vibration-free sample withdrawal speeds can be used to have control over the film thickness.

  6. Compact disc manufacturing - Wikipedia

    en.wikipedia.org/wiki/Compact_Disc_manufacturing

    The spin coater rinses the glass blank with a solvent and then applies either photoresist or dye-polymer depending on the mastering process. Rotation spreads photoresist or dye-polymer coating evenly across the surface of the glass. The substrate is removed and baked to dry the coating and the glass substrate is ready for mastering.

  7. 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 ]

  8. Thin film - Wikipedia

    en.wikipedia.org/wiki/Thin_film

    This allows creating thin films of various molecules such as nanoparticles, polymers and lipids with controlled particle packing density and layer thickness. [6] Spin coating or spin casting, uses a liquid precursor, or sol-gel precursor deposited onto a smooth, flat substrate which is subsequently spun at a high velocity to centrifugally ...

  9. Calo tester - Wikipedia

    en.wikipedia.org/wiki/Calo_tester

    The Calo tester, also known as a ball crater or coating thickness tester, is a simple and inexpensive piece of equipment used to measure the thickness of coatings.Coatings with thicknesses typically between 0.1 to 50 micrometres, such as Physical Vapor Deposition (PVD) coatings or Chemical Vapor Deposition (CVD) coatings, are used in many industries to improve the surface properties of tools ...
