Patent number: 12148751Abstract: Methods for fabricating a transistor arrangement of an IC structure by using a placeholder for backside contact formation, as well as related semiconductor devices, are disclosed. An example method includes forming, in a support structure (e.g., a substrate, a chip, or a wafer), a dielectric placeholder for a backside contact as the first step in the method. A nanosheet superlattice is then grown laterally over the dielectric placeholder, and a stack of nanoribbons is formed based on the superlattice. The nanoribbons are processed to form S/D regions and gate stacks for future transistors. The dielectric placeholder remains in place until the support structure is transferred to a carrier wafer, at which point the dielectric placeholder is replaced with the backside contact. Use of a placeholder for backside contact formation allows alignment of contact from the backside to appropriate device ports of a transistor arrangement.Type: GrantFiled: October 30, 2020Date of Patent: November 19, 2024Assignee: Intel CorporationInventors: Andy Chih-Hung Wei, Anand S.

Patent number: 12107085Abstract: Stacked transistor structures having a conductive interconnect between source/drain regions of upper and lower transistors. In some embodiments, the interconnect is provided, at least in part, by highly doped epitaxial material deposited in the upper transistor's source/drain region. In such cases, the epitaxial material seeds off of an exposed portion of semiconductor material of or adjacent to the upper transistor's channel region and extends downward into a recess that exposes the lower transistor's source/drain contact structure. The epitaxial source/drain material directly contacts the lower transistor's source/drain contact structure, to provide the interconnect. In other embodiments, the epitaxial material still seeds off the exposed semiconductor material of or proximate to the channel region and extends downward into the recess, but need not contact the lower contact structure.Type: GrantFiled: July 7, 2023Date of Patent: October 1, 2024Assignee: Intel CorporationInventors: Aaron D.

Publication number: 20240321859Abstract: An IC device may include an array of transistors. The transistors may have separate gate electrodes. A gate electrode may include polysilicon. The gate electrodes may be separated from each other by one or more electrical insulators. The separated gate electrodes have shorter lengths, compared with connected gate electrodes, which can optimize the performance of the IC device due to local layout effect. Also, the IC device may include conductive structures crossing the support structures of multiple transistors. Such conductive structures may cause strain in the IC device, which can boost the local layout effect. The conductive structures may be insulated from a power plane. Alternatively or additionally, the IC device may include dielectric structures, which may be formed by removing gate electrodes in some of the transistors and providing a dielectric material into the openings. The presence of the dielectric structures can further boost the local layout effect.Type: ApplicationFiled: March 22, 2023Publication date: September 26, 2024Applicant: Intel CorporationInventors: Tao Chu, Minwoo Jang, Yanbin Luo, Paul Packan, Guowei Xu, Chiao-Ti Huang, Robin Chao, Feng Zhang, Anand S.
