Abstract
"2-pole electrical conductivity sensors with chemical resistant carbon electrodes are developed in 2002. These sensors are installed in the semiconductor wet process and used as a densitometer practically. The electrical circuit for 4-pole measurement was an innovation which improved the interface problem to the any 4-pole sensors. Single component concentration of HF or TMAH is measured from the conductivity, based on the precise measurement of conductivity and temperature, via individual temperature compensation of conductivity. Etching or developing solution should be controlled severely. Needs for monitoring solution based on the application of conductivity method are increased."
