A photoresist removal method is provided. The photoresist removal method includes analyzing the process status of each of a number of semiconductor substrate models undergoing a tested plasma ash process by a residue gas analyzer. The tested plasma ash processes for the semiconductor substrate models utilize a plurality of tested recipes. The photoresist removal method further includes selecting one of the tested recipes as a process recipe based on the analysis results from the residue gas analyzer and at least one expected performance criterion. In addition, the photoresist removal method includes performing a plasma ash process on a semiconductor substrate according to the process recipe to remove a photoresist layer from the semiconductor substrate.

Embodiments of the present invention are directed to a method for cleaning a wind turbine blade or a solar panel with a wind cinch device. The method includes applying a cleaning solution to a surface of a wind turbine blade or solar panel; affixing a wind cinch device around a high point of the wind turbine blade or solar panel; applying tension to one or more lines attached to the wind cinch device to control the pressure the wind cinch device applies to the surface of the wind turbine blade or solar panel; and applying tension to the one or more lines attached to the wind cinch device to pull the wind cinch device from the high point on the wind turbine blade or solar panel to a low point on the wind turbine blade or solar panel. Other embodiments of the present invention are directed to a Wind Cinch device. The Wind Cinch device includes a main body, the main body being an elongated member having a cleaning surface sufficient in length to form a loop around a wind turbine blade when wrapped around a wind turbine blade. The Wind Cinch device also includes a plurality of rigging points, each rigging point adapted to receive a line. Applying tension to one or more of the lines attached to the rigging points changes the circumference of the loop formed by wrapping the wind cinch device around the wind turbine blade.
