Laurell
WS-650-8 B
The Laurell WS-650-8 B is a spin coater in the 650-series. The Laurell WS-650-8 B has a maximum substrate size of 200mm (7" x 7"). The Laurell WS-650-8 B has a maximum speed of 12000 rpm.[1]
What it is
The Laurell WS-650-8 B is a spin coater in the 650-series resist-processing class.[1]
How it works
General reference — not yet source-verifiedA spin coater holds a substrate on a rotating chuck and uses centrifugal force to spread a liquid film across the surface.
Spin coating is used to form uniform thin liquid layers on flat substrates before subsequent thermal or exposure steps.
Where it fits in the process flow
The WS-650-8 B can be used in tabletop, in-deck, or on-deck mounting configurations.[1]
Applications
General reference — not yet source-verifiedThe WS-650-8 B is suitable for coating flat substrates that require a controlled thin film.
