Abstract:
The present invention discloses a preparation method of a Cu-based resistive random access memory, and a memory. The preparation method includes: performing composition and a chemical combination treatment on a lower copper electrode ( 10 ) to generate a compound buffer layer ( 40 ), wherein the compound buffer layer ( 40 ) is capable of preventing the oxidation of the lower copper electrode ( 10 ); depositing a solid electrolyte material ( 50 ) on the compound buffer layer ( 40 ); and depositing an upper electrode ( 60 ) on the solid electrolyte material ( 50 ) to form the memory. In the above technical solution, the compound buffer layer ( 40 ) capable of preventing the oxidation of the lower copper electrode ( 10 ) is inserted between the lower copper electrode ( 10 ) and the solid electrolyte material ( 50 ) to efficiently prevent the oxidation of the lower copper electrode ( 10 ) in a growth process of the solid electrolyte material ( 50 ), such that an electrode interface does not become rough due to the oxidation, thereby solving the technical problem of relatively low reliability and yield of the device resulting from the rough electrode interface of the Cu-based resistive random access memory in the prior art, and thus the reliability and the yield of the device are improved.

Claim (Index 9):
A Cu-based resistive random access memory, comprising:\n a lower copper electrode and a dielectric layer, wherein the dielectric layer is arranged above the lower copper electrode, and a pore is formed in the dielectric layer; a compound buffer layer embedded right below the pore in the lower copper electrode, wherein the compound buffer layer is a compound of Cu, Si and N or a compound of Cu, Ge and N; a solid electrolyte material arranged above the compound buffer layer and the dielectric layer and arranged in the wall of the pore; and an upper electrode arranged on the solid electrolyte material.
