Abstract:
A variable resistive element comprising a configuration that an area of an electrically contributing region of a variable resistor body is finer than that constrained by an upper electrode or a lower electrode and its manufacturing method are provided. A bump electrode material is formed on a lower electrode arranged on a base substrate. The bump electrode material is contacted to a variable resistor body at a surface different from a contact surface to the lower electrode. The variable resistor body is contacted to an upper electrode at a surface different from a contact surface to the bump electrode material. Thus, a cross point region between the bump electrode material (the variable resistor body) and the upper electrode becomes an electrically contributing region of the variable resistor body, and then an area thereof can be reduced compared with that of the region regarding the conventional variable resistive element.
