This procedure describes a method for determining the kinematic viscosity of photoresists.
This method, a simplified version of ASTM D445 and ASTM F66 is intended for determining the kinematic viscosity of photoresists by measuring the time for a volume of liquid to flow under gravity through a calibrated glass capillary at a fixed temperature. Efflux time is measured in seconds and multiplied by the calibration constant of the viscometer to obtain kinematic viscosity in units of centistokes (cSt). Optionally, kinematic viscosity may be multiplied by the density of the photoresist to obtain dynamic viscosity in units of centipoise (cP). Refer to ASTM D445 and ASTM F66 for additional information and definitions.
