摘要: A method of captivating a substrate within a holder for photolithographic processing is shown. A substrate is placed within the aperture of a holder and is sandwiched into place by laminating it with layers of dry film photopolymer resist. Portions of the photopolymer resist are polymerized. Unpolymerized portions are washed away leaving retaining tabs of polymerized resist which hold the substrate within the holder for an etching or plating process.
