Abstract:
1. A method for fabricating a resistive memory cell, comprising the following steps: 1) Preparing a substrate; 2) Depositing a metal lower electrode on a surface of the substrate; 3) Depositing a first semiconductor-type oxide layer on the lower electrode; 4) Depositing a resistive material layer on the first semiconductor-type oxide layer and performing an annealing process; 5) Depositing a second semiconductor-type oxide layer on the resistive material layer; and 6) Depositing a metal upper electrode on the second semiconductor-type oxide layer, wherein in each of the steps 2) and 6), the depositing is performed by using a magnetron sputtering method; and in each of the steps 3) to 5), the depositing is performed by using a reaction sputtering method.
