Abstract
Compositions are described that are useful for removing organic and organometallic substances from substrates, for example, photoresist wafers. Processes are presented that apply a minimum volume of a composition as a coating to the inorganic substrate whereby sufficient heat is added and the organic or organometallic substances are completely removed by rinsing. The compositions and processes may be suitable for removing and, in some instances, completely dissolving photoresists of the positive and negative varieties, and specifically negative dry film photoresist from electronic devices.
