Abstract:
A method for manufacturing a semiconductor memory device including following steps is provided. A substrate having a first region, a second region, and a third region is provided. A first stack structure is formed on the first region. A second stack structure is formed on the second region. A third stack structure is formed on the third region. A first mask layer is formed on the substrate to cover the third stack structure. A first ion implantation process is performed, so that a second floating gate and a second control gate in the second stack structure are changed to a first conductive type. A second mask layer formed on the substrate to cover the first and second stack structures. A second ion implantation process is performed, so that a third floating gate and a third control gate in the third stack structure are changed as a second conductive type.

Claim (Index 5):
The method for manufacturing the semiconductor memory device as claimed in  claim 1 , wherein the thickness of the second gate dielectric layer is greater than the thickness of the first gate dielectric layer, and the thickness of the first gate dielectric layer is greater than the thickness of the third gate dielectric layer.
