Abstract
Compositions and methods useful for the removal of organic substances from substrates, for example, electronic device substrates, are provided. A method is presented which uses a minimum amount of solid form concentrate that is diluted into water, introduced into a manufacturing tool and heated, applied to said substrate for a sufficient time to allow penetration and removal of an organic substance, and immediately rinsed with water to achieve complete removal. These compositions and methods are particularly suitable for removing and completely dissolving photoresists of the positive variety most commonly used in the manufacture of a flat panel display (FPD) and other electronic substrates.
