Abstract:
An NOR flash memory comprising a memory cell of a 3D structure and a manufacturing method thereof are provided. The flash memory  100  includes a plurality of columnar portions  120 , a plurality of charge accumulating portions  130  and a plurality of control gates  140 . The columnar portions  120  extend from a surface of a silicon substrate  110  in a vertical direction and include an active region. The charge accumulating portions  130  are formed by way of surrounding a side portion of each columnar portion  120 . The control gates  140  are formed by way of surrounding a side portion of each charge accumulating portion  130 . One end portion of the columnar portion  120  is electrically connected to a bit line  150  via a contact hole, and another end portion of the columnar portion  120  is electrically connected to a conductive region formed on a surface of the silicon substrate  110.

Claim (Index 5):
The NOR flash memory as claimed in  claim 1 , wherein\n the conductive region is a metal layer formed on a silicon substrate and an n +  polysilicon layer on the metal layer, the metal layer is a high melting point silicide layer, and the conductive region constructs a source line, and is commonly connected to the columnar portions.
