ABSTRACT:
A method for cleaning a semiconductor device has the steps of securing a wafer (16) with a modified chuck (11) and applying a cleaning solution (18) to the backside (20) of the wafer (16). The cleaning solution (18) is formulated to remove PTFE from the wafer (16). The cleaning solution (18) is applied to the edge (14) of the wafer (16) because of the characteristics of the modified chuck (11) to remove PTFE impurities that gather on the edge (14) of the wafer (16).
