Paper Abstract

The physical concepts and yield advantages of pellicle protected masks have been reported in many papers. Pellicle disadvantages such as fragility and the hazard of particles trapped under the membrane have been greatly outweighed by the observed chip yield increase. Yet the pellicle provides no protection against static discharge, the dislodgement of previously electrostatically fixed particles, pellicle degradation and surface etch faults.
