Resist chemical
WebThe photoresist areas that develop away after exposure (or after exposure and PEB) are determined by the photoresist's "tone". When the areas exposed to light energy develop away, the photoresist is said to be "positive tone" and if the exposed areas form the pattern after develop, the resist is "negative tone". This is shown schematically below:
