PERFECCIONAMIENTOS INTRODUCIDOS EN ESTRUCTURAS DE CAPA DE RESERVA DE ALTA SENSIBILIDAD PARA EXPOSICION A RADICACIONES DE ALTA ENERGIA. |
摘要 |
A high sensitivity resist layer structure for high energy radiation exposure is formed by coating plural layers of radiation degradable polymers on a substrate which layers are successively slower dissolving in the resist developer. Upon exposure and solvent development, a resist edge profile is obtained which is particularly useful for metal lift-off. |
