Abstract:
A method of cleaning residual photoresist from a semiconductor wafer, comprising the steps of:providing said semiconductor wafer having a quantity of residual photoresist thereon deposited;placing the semiconductor wafer into a processing chamber;spraying a first solvent, comprising N-methylpyrrolidine, maintained in a temperature range of 65.degree. C. to 100.degree. C., onto the semiconductor wafer;discontinuing the spraying of the first solvent onto the semiconductor wafer;spraying a second solvent comprising N-methylpyrrolidine, maintained in a temperature range of 20.degree. C. to 40.degree. C., onto the semiconductor wafer;discontinuing the spraying of the second solvent onto the semiconductor wafer;spraying water, maintained in a temperature range of 20.degree. C. to 40.degree. C., onto the semiconductor wafer; anddiscontinuing the spraying of the water onto the semiconductor wafer.
