MASS BALANCE TEST for Equipment

Mass balance test is one of the environmental measures in the semiconductor industry. It is the comprehensive analysis and measurements of the total amount of chemical, which will be the sum of consumption in the production, effluent and vaporized mist or gas exhaust, supplied to the process.

About above requirement, International SEMATECH Guidelines for Environmental Characterization of Semiconductor Equipment: 06124825B-ENG has been already issued.

In mass balance test for liquid chemical, it needs measurement techniques as well as better understanding semiconductor manufacturing process and grasp its process chemical. So it seems to be difficult for typical analysis company to conduct final mass balance test and prepare report. Safe Techno Limited is engaged in process safety design evaluation of the semiconductor industry for 15+ years, and also has abundant experience in chemical analysis and measurement, so please be assured.

FTIR (Fourier Transform Infrared Spectroscopy) Analysis

For environmental measures, FTIR analysis for process equipment (Wet Station, Coater, Etcher, CVD etc.) emissions characterization is adopting for mass balance test.

The following data is an example of the qualitative and quantitative analysis of the exhaust gas from the equipment during operation of semiconductor manufacturing equipment (SME). In MASS BALANCE TEST, real time qualitative and quantitative analysis of exhaust gas components from the equipment will be possible by using FTIR method.
