发明名称 METHOD OF MANUFACTURING A NON-VOLATILE NAND MEMORY SEMICONDUCTOR INTEGRATED CIRCUIT
摘要 A semiconductor integrated circuit device includes first, second gate electrodes, first, second diffusion layers, contact electrodes electrically connected to the first diffusion layers, a first insulating film which has concave portions between the first and second gate electrodes and does not contain nitrogen as a main component, a second insulating film which is formed on the first insulating film and does not contain nitrogen as a main component, and a third insulating film formed on the first diffusion layers, first gate electrodes, second diffusion layers and second gate electrodes with the second insulating film disposed therebetween in a partial region. The second insulating film is formed to fill the concave portions and a portion between the first and second gate electrodes has a multi-layered structure containing at least the first and second insulating films.
