  • Method for fabricating a semiconductor memory having charge trapping memory cells and semiconductor substrate
    Publication number: 20050003613
    Abstract: Electrically conductive material is introduced into interspaces between the word lines (2) and is partially removed using a mask (6) in such a way that residual portions (7) of the conductive material in each case fill a section of the relevant interspace and produce an electrical contact with source/drain regions (15). With further portions of the conductive material, it is possible to form alignment marks for the fabrication process.
