Method & Evidence

AimHow can alternative ozonated chemistries in a single-wafer backside cleaning process reduce the environmental footprint compared to conventional methods in semiconductor manufacturing?
MethodLife Cycle Impact Assessment (LCIA) using the Environmental Footprint 3.1 framework.
ProcedureThe methodology was applied to a backside wet cleaning process in a 300 mm semiconductor pilot line. A proposed single-wafer process using ozonated chemistries was compared against a baseline process (Spin Cleaning with Repetitive use of Ozonated water and Diluted HF). Environmental impacts were quantified, and a sensitivity analysis was conducted on factors like electricity source.
