CELLULE MEMOIRE ELECTRONIQUE A DOUBLE GRILLE ET PROCEDE DE FABRICATION D'UNE TELLE CELLULE

摘要

The cell (100) has a lower face (114) in contact with a stack zone such that the zone separates a part (103-2) of a channel (103) and the lower face. An upper face (115) is plane and parallel to a substrate plane. Lateral faces (113, 116) connect the lower face to the upper face. One of the lateral faces is inclined at an angle strictly between 0 and 90 degrees relative to the plane of the substrate such that length (L) of the upper face is strictly greater than length (L-MG) of the lower face. The lengths are measured as distance between the lateral faces over length of the channel. An independent claim is also included for a method for manufacturing a memory cell.
