Abstract: An integrated circuit includes: a gate dielectric; a first layer adjacent to the gate dielectric; a second layer adjacent to the first layer, the second layer comprising an amorphous material; a third layer adjacent to the second layer, the third layer comprising a crystalline material; and a source or drain at least partially adjacent to the third layer. In some cases, the crystalline material of the third layer is a first crystalline material, and the first layer comprises a second crystalline material, which may be the same as or different from the first crystalline material. In some cases, the gate dielectric includes a high-K dielectric material. In some cases, the gate dielectric, the first layer, the second layer, the third layer, and the source or drain are part of a back-gate transistor structure (e.g., back-gate TFT), which may be part of a memory structure (e.g., located within an interconnect structure).
