PURPOSE: A vertical NAND flash memory device with an oxide semiconductor channel is provided to indefinitely increase the number of cells per a unit area, thereby drastically increasing the integration degree of devices. CONSTITUTION: A vertical oxide semiconductor channel(160) is long toward the top of a substrate(100). A lower insulating layer(110), a laminated structure(120), a tunneling insulating film(130), a charge capturing film(140), and an upper insulating layer(170) surround the vertical channel. A blocking insulating film(150) is formed between the charge capturing film and the laminated structure. The vertical oxide semiconductor channel is made of IGZO(In,Ga,Zn,O).
