ABSTRACT:
The two-terminal nonlinear element of this invention includes: a lower electrode having a flat top surface and tapered side walls; a thinner insulating film formed on a portion of the flat top surface of the lower electrode adjacent to the boundary with the tapered side walls; thicker insulating films formed on the flat top surface of the lower electrode except for the portion where the thinner insulating film is formed and on the tapered side walls; and an upper electrode formed on the thinner insulating film.
