NONVOLATILE SEMICONDUCTOR MEMORY DEVICE AND METHOD FOR MANUFACTURING SAME
摘要:
In a nonvolatile semiconductor memory device, a stacked body is formed by alternately stacking dielectric films and conductive films on a silicon substrate and a plurality of through holes extending in the stacking direction are formed in a matrix configuration. A shunt interconnect and a bit interconnect are provided above the stacked body. Conductor pillars are buried inside the through holes arranged in a line immediately below the shunt interconnect out of the plurality of through holes, and semiconductor pillars are buried inside the remaining through holes. The conductive pillars are formed from a metal, or low resistance silicon. Its upper end portion is connected to the shunt interconnect and its lower end portion is connected to a cell source formed in an upper layer portion of the silicon substrate.
