Abstract

The inventive method provides a wet cleaning of semiconductor devices on semiconductor wafers after photoresist is stripped. Semiconductor wafers are placed into a centrifuge carriage of a processing chamber. The centrifuge carriage rotates the semiconductor wafers. N-methylpyrrolidine heated to a temperature between 65.degree. C. and 85.degree. C. is sprayed onto the semiconductor wafers. Next N-methylpyrrolidine at room temperature is sprayed onto the semiconductor wafers. Finally, water at room temperature is sprayed onto the semiconductor wafers. The inventive method provides high throughput cleaning without undue corrosion or damage to metal layers.
