Abstract

A thin film capacitor comprising an insulating substrate, a capacitor structure located on the substrate, the capacitor structure having a dielectric layer sandwiched between a lower electrode layer and an upper electrode layer, and conductor members respectively connected to the lower electrode layer and the upper electrode layer, wherein at least the dielectric layer has a side face having a sufficient slope for preventing the short circuit of the upper electrode layer with the lower electrode layer through the conductor member. A method of manufacturing such a thin film capacitor is also disclosed.
