Method for wet stripping silicon-containing organic layers

A method for stripping material from a microelectronic workpiece is described. The method includes receiving a workpiece having a surface exposing a layer composed of silicon and organic material, and placing the workpiece in a wet clean chamber. In the wet clean chamber, the layer composed of silic...

Zusammenfassung:A method for stripping material from a microelectronic workpiece is described. The method includes receiving a workpiece having a surface exposing a layer composed of silicon and organic material, and placing the workpiece in a wet clean chamber. In the wet clean chamber, the layer composed of silicon and organic material is removed from the workpiece by exposing the surface of the workpiece to a first stripping agent containing a sulfuric acid composition, and then optionally exposing the surface of the workpiece to a second stripping agent containing dilute hydrofluoric acid (dHF).
