摘要:
A stack gate structure for a non-volatile memory array has a semiconductor substrate having a plurality of substantially parallel spaced apart active regions, with each active region having an axis in a first direction. A first insulating material is between each stack gate structure in the second direction perpendicular to the first direction. Each stack gate structure has a second insulating material over the active region, a charge holding gate over the second insulating material, a third insulating material over the charge holding gate, and a first portion of a control gate over the third insulating material. A second portion of the control gate is over the first portion of the control gate and over the first insulating material adjacent thereto and extending in the second direction. A fourth insulating material is over the second portion of the control gate.

摘要:
Le transistor à effet de champ comporte un substrat comprenant successivement un substrat de support (1) électriquement conducteur, une couche électriquement isolante (2) et une couche en matériau semi-conducteur (3). La contre-électrode (4) est formée dans une première portion (9) du substrat de support (1) face à la couche en matériau semi-conducteur (3). Le motif d'isolation (5) entoure la couche en matériau semi-conducteur (3) pour délimiter une première zone active (7) et il s'enfonce partiellement dans la couche de support (1) pour délimiter la première portion (9). Un contact (14) électriquement conducteur traverse le motif d'isolation (5) depuis une première face latérale en contact avec la contre-électrode (4) jusqu'à une seconde face. Le contact est connecté électriquement à la contre-électrode (4).
