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.
SU-8 molecule. SU-8 is a commonly used epoxy-based negative photoresist.Negative refers to a photoresist whereby the parts exposed to UV become cross-linked, while the remainder of the film remains soluble and can be washed away during development.
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.
Spin casting, also known as centrifugal rubber mold casting (CRMC), is a method of utilizing inertia to produce castings from a rubber mold. Typically, a disc-shaped mold is spun along its central axis at a set speed.
Since the foundation of the company GMA in 1989, which emerged from the former Elektromat, in Sacka near Dresden, Suss Microtec has been producing its own systems for testing micro components. In 1993, Suss Microtec expanded its product range with the acquisition of the French S.E.T. to include spin coaters and device bonders.
Made of commercial-grade aluminum with a PFOA-free nonstick coating, you can use this pan on glass, electric and ceramic glass stovetops, plus it's safe to put in the oven (at 400°F with the ...
We tested the 6.5' tree with clear incandescent lights. If you opt for the 6.5' tree without lights, it's only $299 today — or $250 off its regular price. But for our money, we recommend a lit tree.
Sputter coating in scanning electron microscopy is a sputter deposition process [clarification needed] to cover a specimen with a thin layer of conducting material, typically a metal, such as a gold/palladium (Au/Pd) alloy. A conductive coating is needed to prevent charging of a specimen with an electron beam in conventional SEM mode (high ...
