(EN) INTEGRATED ASSEMBLIES AND METHODS OF FORMING INTEGRATED ASSEMBLIES
(FR) ENSEMBLES INTÉGRÉS ET PROCÉDÉS DE FORMATION D'ENSEMBLES INTÉGRÉS
Abstract
(EN) Some embodiments include an integrated assembly having a memory region and another region adjacent the memory region. Channel-material-pillars are arranged within the memory region, and conductive posts are arranged within said other region. A source structure is coupled to lower regions of the channel-material-pillars. A panel extends across the memory region and said other region, and separates a first memory-block- region from a second memory-block-region. Doped-semiconductor-material is directly adjacent to the panel within the memory region and the other region. Rings laterally surround lower regions of the conductive posts. The rings are between the conductive posts and the doped- semiconductor- material. The rings include laminates of two or more materials, with at least one of said two or more materials being insulative. Some embodiments include methods for forming integrated assemblies.
(FR) Certains modes de réalisation de la présente invention comprennent un ensemble intégré ayant une région de mémoire et une autre région adjacente à la région de mémoire. Des colonnes de matériau de canal sont disposées à l'intérieur de la région de mémoire, et des tiges conductrices sont agencées à l'intérieur de ladite autre région. Une structure source est couplée à des régions inférieures des piliers en matériau de canal. Un panneau s'étend à travers la région de mémoire et ladite autre région, et sépare une première région de bloc de mémoire d'une seconde région de bloc de mémoire. Le matériau semi-conducteur dopé est directement adjacent au panneau à l'intérieur de la région de mémoire et de l'autre région. Des anneaux entourent latéralement des régions inférieures des montants conducteurs. Les anneaux se trouvent entre les montants conducteurs et le matériau semi-conducteur dopé. Les bagues comprennent des stratifiés d'au moins deux matériaux, au moins l'un desdits deux matériaux ou plus étant isolant. Certains modes de réalisation comprennent des procédés de formation d'ensembles intégrés.
