A system and method for anti-reflective layers is provided. In an embodiment the anti-reflective layer comprises a floating additive in order to form a floating additive region along a top surface of the anti-reflective layer after the anti-reflective layer has dispersed. The floating additive may comprise an additive group which will decompose along with a fluorine unit bonded to the additive group which will decompose. Additionally, adhesion between the middle layer and the photoresist may be increased by applying an adhesion promotion layer using either a deposition process or phase separation, or a cross-linking may be performed between the middle layer and the photoresist.
