What it is

General reference — not yet source-verified

Photoresist spinners are used to apply a uniform layer of photosensitive polymer onto a substrate. The substrate is held on a vacuum chuck and spun at high speed. Liquid resist dispensed onto the center spreads radially by centrifugal force. Spin speed and acceleration control the final thickness.

How it works

General reference — not yet source-verified

A photoresist spinner operates by accelerating a substrate to a controlled rotational speed. A small volume of liquid photoresist is dispensed onto the center of the substrate while it is either stationary or spinning slowly. The spin speed is then ramped up to the desired process speed, causing the resist to spread evenly and thin to a uniform coating. The vacuum chuck holds the substrate in place through a vacuum applied through the chuck. After coating, the substrate is typically removed and subjected to a soft bake to evaporate solvents.

Where it fits in the process flow

General reference — not yet source-verified

In semiconductor manufacturing, photoresist spinners are part of the lithography sequence. A clean wafer is first primed, then coated with photoresist in the spinner. After coating, the wafer moves to a soft bake step and then to exposure. The spinner is typically a standalone benchtop or integrated track module.
