Publication number: 20220359758Abstract: Transistors with metal oxide channel material and a multi-composition gate dielectric. A surface of a metal oxide gate dielectric may be nitrided before deposition of a metal oxide channel material, for example to reduce gate capacitance of a TFT. Breakdown voltage and/or drive current of a TFT can be increased through the introduction of an additional metal oxide and/or nitride between the gate electrode and a metal oxide gate dielectric. The introduction of an intervening layer between two layers of a metal oxide gate dielectric can also increase breakdown voltage and/or drive current of a TFT.Type: ApplicationFiled: May 5, 2021Publication date: November 10, 2022Applicant: Intel CorporationInventors: Shailesh Kumar Madisetti, Chieh-Jen Ku, Wen-Chiang Hong, Pei-Hua Wang, Cheng Tan, Harish Ganapathy, Bernhard Sell, Lin-Yung Wang

Publication number: 20220208770Abstract: Described herein are embedded dynamic random-access memory (eDRAM) memory cells and arrays, as well as corresponding methods and devices. An exemplary eDRAM memory array implements a memory cell that uses a thin-film transistor (TFT) as a selector transistor. One source/drain (S/D) electrode of the TFT is coupled to a capacitor for storing a memory state of the cell, while the other S/D electrode is coupled to a bitline. The bitline may be a shallow bitline in that a thickness of the bitline may be smaller than a thickness of one or more metal interconnects provided in the same metal layer as the bitline but used for providing electrical connectivity for components outside of the memory array. Such a bitline may be formed in a separate process than said one or more metal interconnects. In an embodiment, the memory cells may be formed in a back end of line process.Type: ApplicationFiled: March 17, 2022Publication date: June 30, 2022Applicant: Intel CorporationInventors: Yih Wang, Abhishek A.
