Etch resistance
Positive: light will weaken the resist, and create a hole Negative: light will toughen the resist and create an etch resistant mask. To explain this in graphical form you may have a graph on Log exposure energy versus fraction of resist thickness remaining. The positive resist will be completely removed at the final exposure energy and the negative resist will b… Positive: light will weaken the resist, and create a hole Negative: light will toughen the resist and create an etch resistant mask.
