Patent number: 11955515Abstract: A semiconductor device with dual side source/drain (S/D) contact structures and a method of fabricating the same are disclosed. The method includes forming a fin structure on a substrate, forming a superlattice structure on the fin structure, forming first and second S/D regions within the superlattice structure, forming a gate structure between the first and second S/D regions, forming first and second contact structures on first surfaces of the first and second S/D regions, and forming a third contact structure, on a second surface of the first S/D region, with a work function metal (WFM) silicide layer and a dual metal liner. The second surface is opposite to the first surface of the first S/D region and the WFM silicide layer has a work function value closer to a conduction band energy than a valence band energy of a material of the first S/D region.Type: GrantFiled: July 28, 2022Date of Patent: April 9, 2024Assignee: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Shih-Chuan Chiu, Chia-Hao Chang, Cheng-Chi Chuang, Chih-Hao Wang, Huan-Chieh Su, Chun-Yuan Chen, Li-Zhen Yu, Yu-Ming Lin

Publication number: 20240107776Abstract: An antiferroelectric field effect transistor (Anti-FeFET) of a memory cell includes an antiferroelectric layer instead of a ferroelectric layer. The antiferroelectric layer may operate based on a programmed state and an erased state in which the antiferroelectric layer is in a fully polarized alignment and a non-polarized alignment (or a random state of polarization), respectively. This enables the antiferroelectric layer in the FeFET to provide a sharper/larger voltage drop for an erase operation of the FeFET (e.g., in which the FeFET switches or transitions from the programmed state to the erased state) relative to a ferroelectric material layer that operates based on switching between two opposing fully polarized states.Type: ApplicationFiled: January 5, 2023Publication date: March 28, 2024Inventors: Chun-Chieh LU, Chih-Yu CHANG, Yu-Chuan SHIH, Huai-Ying HUANG, Yu-Ming LIN
