Diazonaphthoquinone (DNQ) is a diazo derivative of naphthoquinone. Upon exposure to light it undergoes a Wolff rearrangement to form a ketene. This chemical reaction is exploited with a variety of diazonaphthoquinone derivatives in the semiconductor industry.Diazonaphthoquinone sulfonic acid esters are commonly used as components of photoresist materials for semiconductor manufacturing. In this application DNQs are mixed with Novolac resin a type of phenolic polymer.
