In the photoresist processing of various products, the resist, after being developed, is stripped. It is typically stripped in a solution where resist settles in the process tank in a semi-solidified form, where it must be removed. A device for removing the resist works in the following manner. As seen in the drawing, the tool 1 is made of titanium and consists of opposing jaws 2 that pivot at point A. The tool removes resist by entering the process tank (not shown), to be cleaned, with the flat edges 3 of jaws 2 moving down on an X-axis on the side of the tank to be cleaned. As tool 1 lowers into the tank, it gathers resist until the resist solution reaches the top of edge 3 when the tool is closed by rotating opposing jaws 2 about point A until fully closed.
