Abstract: A semiconductor manufacturing apparatus according to an embodiment includes a rotor, a nozzle, a first electrode, and a second electrode. The rotor is configured to hold a substrate and to rotate the substrate. The substrate has an outer-periphery portion and a circumferential edge. The circumferential edge is located outside the outer-periphery portion. The nozzle is configured to supply a resist liquid to the outer-periphery portion of the substrate. The first electrode is configured to receive a voltage that applies an electric charge to the resist liquid ejected from the nozzle. The second electrode is disposed at a position different from that of the first electrode. The second electrode is configured to receive a voltage that causes a Coulomb force to act on the resist liquid.

Abstract: According to one embodiment, an exposure apparatus performs exposure to transcribe a circuit pattern onto each of a plurality of sections on a wafer. The exposure apparatus includes a measurement device and a control device. The control device sets, on each of a first section and a second section adjacent to each other among the plurality of sections, a measurement point at a position offset from a reference position of each section. The control device causes the measurement device to measure surface information at each measurement point. The control device executes focus leveling control for exposure on the basis of the surface information measured at each measurement point.

Abstract: According to one embodiment, there is provided a semiconductor device, which includes an electrode lead-out part, a planarization film, contacts, and first and second columnar patterns. The electrode lead-out part is arranged such that an electrode film and an insulating film are alternately stacked in a plurality of layers, and layers of the electrode film are arranged stepwise. The planarization film is arranged above the electrode lead-out part. The first columnar pattern extends from a lowermost portion of the electrode lead-out part to a position lower than the upper side of the planarization film by a first depth. The second columnar pattern extends from a lowermost portion of the electrode lead-out part to a position lower than the upper side of the planarization film by a second depth larger than the first depth.

Abstract: A nonvolatile semiconductor memory device comprises: a memory cell region having a memory cell disposed therein; a peripheral region including a first stepped structure in which an end of a lower first layer is further from the memory cell region than is an end of an upper first layer; and a second stepped structure disposed on the first stepped structure, in which an end of a lower third layer is disposed further from the memory cell region than is an end of an upper third layer, a length in a second direction being shorter than a length in the second direction of the first layer or the second layer contacted by the second stepped structure, and a length in a third direction of the second stepped structure being shorter than a length in the third direction of the first layer or the second layer contacted by the second stepped structure.
