Publication number: 20240105452Abstract: Techniques are provided to form semiconductor devices that include one or more gate cuts having a layer of polymer material at edges of the gate cut. The polymer layer may be provided as a byproduct of the etching process used to form the gate cut recess through the gate structure, and can protect any exposed portions of the source or drain regions from certain subsequent processes. The gate structure may be interrupted between two transistors with a gate cut that extends through an entire thickness of the gate structure and includes a dielectric material to electrically isolate the portions of the gate structure on either side of the gate cut. The edges of the gate cut may be lined with a polymer layer that is also on any exposed portions of the source or drain regions that were exposed during the etching process used to form the gate cut recess.Type: ApplicationFiled: September 26, 2022Publication date: March 28, 2024Applicant: Intel CorporationInventors: Reza Bayati, Matthew J. Prince, Alison V. Davis, Chun C. Kuo, Andrew Arnold, Ramy Ghostine, Li Huey Tan

Publication number: 20230352598Abstract: 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).Type: ApplicationFiled: June 30, 2023Publication date: November 2, 2023Applicant: Intel CorporationInventors: Van H. Le, Abhishek A. Sharma, Gilbert Dewey, Kent Millard, Jack Kavalieros, Shriram Shivaraman, Tristan A. Tronic, Sanaz Gardner, Justin R. Weber, Tahir Ghani, Li Huey Tan, Kevin Lin

Patent number: 11742429Abstract: 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.Type: GrantFiled: October 22, 2021Date of Patent: August 29, 2023Assignee: Intel CorporationInventors: Abhishek A. Sharma, Van H. Le, Li Huey Tan, Tristan A. Tronic, Benjamin Chu-Kung, Jack T. Kavalieros, Tahir Ghani
