  • METHOD OF PREDICTING EUV DOSE, METHOD OF DESIGNING PAG USING THE SAME, AND METHOD OF MANUFACTURING SEMICONDUCTOR DEVICE USING THE SAME
    Publication number: 20250044706
    Abstract: In a method of predicting extreme ultraviolet (EUV) dose, an entire photochemical reaction mechanism until a photoacid generator (PAG) molecule releases a proton from a PAG-cation under EUV exposure may be analyzed. A lowest unoccupied molecular orbital (LUMO) energy level may be obtained by performing a simulation for structural optimization of the PAG-cation. An additional parameter different from the LUMO energy level may be obtained by performing a simulation for structural optimization of at least one intermediate molecular structure formed by the entire photochemical reaction mechanism. A two-parameter linear regression model for predicting the EUV dose may be obtained based on the LUMO energy level and the additional parameter.
