Methods and apparatus for forming an integrated circuit device, including performing a spin-cleaning step at a first rotational speed on a semiconductor substrate supporting the integrated circuit device at an intermediate stage of manufacturing. A rinse fluid is then dispensed over a top surface of the substrate. A rotational speed of the substrate is increased with a constant acceleration no greater than 125 revolutions per minute per second (rpm/s) from the first rotational speed to a second rotational speed. The second rotational speed is maintained for a rinse fluid extraction period. The rotational speed is then reduced to zero.
