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).

Described is an apparatus which comprises: a gate comprising a metal; a first layer adjacent to the gate, the first layer comprising a dielectric material; a second layer adjacent to the first layer, the second layer comprising a second material; a third layer adjacent to the second layer, the third layer comprising a third material including an amorphous metal oxide; a fourth layer adjacent to the third layer, the fourth layer comprising a fourth material, wherein the fourth and second materials are different than the third material; a source partially adjacent to the fourth layer; and a drain partially adjacent to the fourth layer.

Techniques are disclosed for forming thin-film transistors (TFTs) with low contact resistance. As disclosed in the present application, the low contact resistance can be achieved by intentionally thinning one or both of the source/drain (S/D) regions of the thin-film layer of the TFT device. As the TFT layer may have an initial thickness in the range of 20-65 nm, the techniques for thinning the S/D regions of the TFT layer described herein may reduce the thickness in one or both of those S/D regions to a resulting thickness of 3-10 nm, for example. Intentionally thinning one or both of the S/D regions of the TFT layer induces more electrostatic charges inside the thinned S/D region, thereby increasing the effective dopant in that S/D region. The increase in effective dopant in the thinned S/D region helps lower the related contact resistance, thereby leading to enhanced overall device performance.

A cap of insulating material is located above the void and defines an upper boundary of the void such that the void is further located between the base and the cap of insulating material. In some embodiments, one or more vias contacts an upper end of one or more of the conductive lines.
