Capacitor structure and manufacturing method thereof

Abstract

The invention provides a capacitor structure and the manufacturing method thereof. The capacitor structure includes a first conductor layer, a dielectric layer and a second conductor layer, wherein the first conductor is provided with a first metal material and a second metal material, clearances are formed in the first metal material and filled with the second metal material through hot melting; therefore, the first conductor layer can effectively lower heat treatment temperature through the mutual hot melting relationship between the first metal material and the second metal material, and the capacitor structure also achieves the effects of improving electrical conductivity and enhancing whole intensity at the same time.

Description

technical field [0001] The invention relates to a capacitor structure and a manufacturing method thereof, in particular to a capacitor structure and a manufacturing method thereof which use combined composite materials to increase conductivity and reduce heat treatment temperature. Background technique [0002] In recent years, for electronic integrated circuits, it is required to operate at lower voltage, higher frequency, and lower noise. For solid electrolytic capacitors, for the reduction of ESR (equivalent series resistance), ESL (equivalent series inductance) Inductance) reduction requirements are also increasing. Metal powders suitable for anode materials of solid electrolytic capacitors include, for example, tantalum, niobium, titanium, tungsten, and molybdenum. Among them, capacitors using tantalum are rapidly spreading as parts of cell phones, personal computers, and the like due to their low ESR and large capacitance. Recently, higher capacity and lower ESR of c...
