  • Patent number: 11751397
    Abstract: In one embodiment, a semiconductor storage device includes a stacked body in which a plurality of conducting layers are stacked through a plurality of insulating layers in a first direction, a semiconductor layer penetrating the stacked body, extending in the first direction and including metal atoms, and a memory film including a first insulator, a charge storage layer and a second insulator that are provided between the stacked body and the semiconductor layer. The semiconductor layer surrounds a third insulator penetrating the stacked body and extending in the first direction, and at least one crystal grain in the semiconductor layer has a shape surrounding the third insulator.
    Type: Grant

  • Publication number: 20220301896
    Abstract: A substrate processing apparatus includes a chamber, a supply pipe, a discharge pipe, a trap section, a heater, a buffer section, and a cooling pipe. The chamber houses a substrate. The supply pipe supplies a processing gas into the chamber. The discharge pipe discharges a gas produced in the chamber. The trap section is disposed in the discharge pipe. The heater heats the trap section. The buffer section is disposed downstream of the trap section in the discharge pipe. The cooling pipe cools the buffer section.
