Abstract: A low strain transfer protective layer is formed on a transition metal dichalcogenide (TMD) monolayer to enable the transfer of the TMD monolayer from a growth substrate to a target substrate with little or no strain-induced damage to the TMD monolayer. Transfer of a TMD monolayer from a growth substrate to a target substrate comprises two transfers, a first transfer from the growth substrate to a carrier wafer and a second transfer from the carrier wafer to the target substrate. Transfer of the TMD monolayer from the growth substrate to the carrier wafer comprises mechanically lifting off the TMD monolayer from the growth substrate. The low strain transfer protective layer can limit the amount of strain transferred from the carrier wafer to the TMD monolayer during lift-off. The carrier wafer and protective layer are separated from the TMD monolayer after attachment of the TMD monolayer to the target substrate.

Abstract: Described herein are ferroelectric (FE) memory cells that include transistors having gate stacks separate from FE capacitors of these cells. An example memory cell may be implemented as an IC device that includes a support structure (e.g., a substrate) and a transistor provided over the support structure and including a gate stack. The IC device also includes a FE capacitor having a first capacitor electrode, a second capacitor electrode, and a capacitor insulator of a FE material between the first capacitor electrode and the second capacitor electrode, where the FE capacitor is separate from the gate stack (i.e., is not integrated within the gate stack and does not have any layers that are part of the gate stack). The IC device further includes an interconnect structure, configured to electrically couple the gate stack and the first capacitor electrode.

Abstract: A method for fabricating floating body memory cells (FBCs), and the resultant FBCs where gates favoring different conductivity type regions are used is described. In one embodiment, a p type back gate with a thicker insulation is used with a thinner insulated n type front gate. Processing, which compensates for misalignment, which allows the different oxide and gate materials to be fabricated is described.
