Single-wafer process for fabricating a nonvolatile charge trap memory device

摘要

A method for fabricating a nonvolatile charge trap memory device is described. The method includes first forming a tunnel dielectric layer on a substrate in a first process chamber of a single-wafer cluster tool. A charge-trapping layer is then formed on the tunnel dielectric layer in a second process chamber of the single-wafer cluster tool. A top dielectric layer is then formed on the charge-trapping layer in the second or in a third process chamber of the single-wafer cluster tool.
