Assignee: BESANG, INC.
Field: Semiconductors (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 40:
41. A 3D NVM module, comprising:
conductive lines;
semiconductor pillars formed on said conductive lines, and arranged in an array, and forming bodies of vertical transistors;
a composite gate dielectric disposed on each of said semiconductor pillars; and
a control gate disposed on said composite gate dielectric and surrounding a middle portion of each of said semiconductor pillars;
word lines disposed over said vertical transistors;
metal lines disposed over said vertical transistors;
and wherein:
said array has a bit-line direction and a word-line direction, perpendicular to each other;
said conductive lines are sufficiently narrow in said word-line direction such that each of said conductive lines can accommodate only one of said vertical transistors in said word-line direction;
said word lines are coupled to said control gate of said vertical transistors which are respectively arranged along said word-line direction;
said metal lines are coupled to a top region of said vertical transistors which are respectively arranged along said bit-line direction; and
said metal lines run parallel with said conductive lines.
