What it is
The Laurell WS 400 B 6 NP P is a spin coater.[1]
How it works
General reference — not yet source-verifiedSpin coaters operate by placing a substrate on a rotating chuck. Liquid photoresist is dispensed onto the center of the substrate while it spins at high speed. Centrifugal force spreads the liquid outward, creating a thin, even coating. The final film thickness is determined by spin speed, acceleration, and the properties of the resist.
Where it fits in the process flow
General reference — not yet source-verifiedIn the photolithography process, spin coating follows substrate cleaning and dehydration steps. The coated substrate then undergoes a soft bake to remove solvents before exposure. The spin coater is typically located in a cleanroom environment dedicated to coating and developing.
