1. A method for cleaning and drying a front and a back surface of a semiconductor substrate, the method comprising:

  • brush scrubbing the back surface of the semiconductor substrate using a brush scrubbing chemistry;

    forming a front fluid meniscus with the front surface of the semiconductor substrate and a back fluid meniscus with the back surface of the semiconductor substrate, the forming of the front and the back fluid menisci being performed after the brush scrubbing of the back surface; and

    scanning the front surface of the semiconductor substrate and the back surface of the semiconductor substrate by moving the front meniscus along the front surface of the semiconductor substrate and the back fluid meniscus along the back surface of the semiconductor substrate, the front and back fluid menisci being formed using a chemistry that is compatible with the brush scrubbing chemistry,wherein scanning the front surface of the substrate and the back surface of the substrate is configured to clean and dry the front surface of the substrate and the back surface of the substrate.
