  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. Drawdown chart - Wikipedia

    en.wikipedia.org/wiki/Drawdown_chart

    The bars are generally made of stainless steel or aluminum and touch the chart at each end, while the center is slightly raised to a desired height in order to obtain the desired film thickness. [3] As with the charts, the bars have to be especially resistant to corrosion because of the corrosive nature of some coatings. [4]

  4. 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 ...

  5. 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 ]

  6. 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.

  7. 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 ...

  8. Rotational molding - Wikipedia

    en.wikipedia.org/wiki/Rotational_molding

    In order to form an even thickness throughout the part, the mold rotates at all times during the heating phase, and then continues to rotate during the cooling phase to avoid sagging or deformation. The process was applied to plastics in the 1950s but in the early years was little used because it was a slow process restricted to a small number ...

  9. Adhesive bonding of semiconductor wafers - Wikipedia

    en.wikipedia.org/wiki/Adhesive_bonding_of...

    The adhesive layer thickness should be larger than the flatness imperfection of the wafer to establish good contact. [3] The procedural steps based on a typical example are: Cleaning Top wafer; Thermal oxidation; Dehydration; Spin coating the SU-8; Softbake 120 s at 65 °C; 300 s to 95 °C; Cooling down; Exposure with 165 to 200 mJ ⁄ cm 3 ...
