Publication number: 20240008273Abstract: According to one embodiment, a semiconductor device manufacturing method includes forming a stacked film with alternating first-type sacrificial layers and second-type sacrificial layers, then removing the first-type sacrificial layers from the stacked film to leave the second-type sacrificial layers with spaces therebetween. The second-type sacrificial layers are then each replaced with an insulating layer after removing the first-type sacrificial layers. After the second-type sacrificial layers are replaced with the insulating layer, a conductive layer is formed inside the spaces formed by removing the first-type sacrificial layers.Type: ApplicationFiled: January 9, 2023Publication date: January 4, 2024Inventors: Rikyu IKARIYAMA, Shinya OKUDA, Takuya KONNO
