Abstract:
A three-dimensional memory device including self-aligned drain select level electrodes is provided. Memory stack structures extend through an alternating stack of insulating layers and spacer material layers. Each of the memory stack structures includes a memory film and a memory level channel portion. Drain select level channel portions are formed over the memory level channel portions with respective lateral shifts with respect to underlying memory stack structures. The direction of lateral shifts alternates from row to row for each row of drain select level channel portions. Drain select level gate dielectrics and drain select level gate electrodes are formed on the drain select level channel portions. Each drain select level gate electrode controls two rows of drain select level channel portions, and is laterally spaced from neighboring drain select level gate electrodes.
Abstract:
A method of forming an electronic device includes forming an oxygen scavenging layer (230) proximate to a dielectric layer (204) in a gate region of a field effect transistor (FET). An interface layer (214) is between the dielectric layer and a substrate of the FET. The method further includes forming a dipole layer by annealing the oxygen scavenging layer, the dielectric layer, and the interface layer.

Abstract:
A non- volatile memory cell includes a substrate of a first conductivity type, having a first region of a second conductivity type, a second region of the second conductivity type spaced apart from the first region, forming a channel region therebetween. A floating gate is disposed over and insulated from a first portion of the channel region which is adjacent the first region. A select gate is disposed over a second portion of the channel region adjacent to the second region, the select gate being formed of a metal material and being insulated from the second portion of the channel region by a layer of silicon dioxide and a layer of high K insulating material. A control gate is disposed over and insulated from the floating gate. An erase gate is disposed over and insulated from the first region, and disposed laterally adjacent to and insulated from the floating gate.
