Document Type and Number:
Japanese Patent JP7405100
Kind Code:
B2
Abstract:
Provided is a decomposing/cleaning composition for an adhesive polymer having a high etching rate and suppressed infiltration into a contact interface between a substrate such as a device wafer and an adhesive layer such as a fixing tape. The decomposing/cleaning composition of one embodiment is a decomposing/cleaning composition for an adhesive polymer containing a quaternary alkylammonium fluoride or a quaternary alkylammonium fluoride hydrate and an aprotic solvent, wherein the aprotic solvent contains (A) an N-substituted amide compound having no active hydrogens on the nitrogen atoms and (B) at least one organic sulfur oxide selected from the group consisting of sulfoxide compounds and sulfone compounds.
