CAPACITOR LAYER FORMING MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a capacitor layer forming material capable of simultaneously improving the average capacity density of a dielectric layer possessed by the capacitor layer forming material and reduction in leak current density. Ž

SOLUTION: This capacitor layer forming material has the dielectric layer between a first conductive layer used for forming an upper electrode and a second conductive layer used for forming a lower electrode. The capacitor layer forming material is adopted in such a way that the second conductive layer is a nickel layer having a purity of 99.99 wt.% or higher, and the dielectric layer includes manganese in a range of 0.25-1.00 mol% with the total quantity of barium, strontium and titanium as 100 mol% in a composition of (BaxSr1-x)TiO3(0≤x≤1).
