Abstract:
According to one embodiment, a semiconductor device includes: a first transistor including a first stack in which a first oxide, a first nitride, a first conductor, and a second nitride are subsequently stacked; and first regions bracketing the first stack; and a second transistor including a second stack in which a second oxide, a second conductor, and a third nitride are subsequently stacked; and second regions bracketing the second stack, wherein the first transistor further includes a third oxide provided on the first regions and a fourth nitride consecutively provided on the third oxide and the second nitride, and the second transistor further includes a fourth oxide consecutively provided on the second regions and the third nitride, and a fifth nitride provided on the fourth oxide.

Claim (Index 7):
The device of  claim 1 , further comprising a contact plug provided on the first conductor so as to penetrate the second nitride and the fourth nitride,\n wherein the contact plug includes: a first portion of the contact plug having a lower surface which is in contact with the first conductor; a second portion of the contact plug provided above the first portion of the contact plug; and a third portion of the contact plug having a lower surface which is in contact with an upper surface of the first portion of the contact plug and has an area greater than that of the upper surface of the first portion of the contact plug, having an upper surface which is in contact with a lower surface of the second portion of the contact plug and has an area greater than that of the lower surface of the second portion of the contact plug, and electrically coupling the first portion of the contact plug and the second portion of the contact plug.
