Patent number: 11887891Abstract: A transistor comprises a substrate, a pair of spacers on the substrate, a gate dielectric layer on the substrate and between the pair of spacers, a gate electrode layer on the gate dielectric layer and between the pair of spacers, an insulating cap layer on the gate electrode layer and between the pair of spacers, and a pair of diffusion regions adjacent to the pair of spacers. The insulating cap layer forms an etch stop structure that is self aligned to the gate and prevents the contact etch from exposing the gate electrode, thereby preventing a short between the gate and contact. The insulator-cap layer enables self-aligned contacts, allowing initial patterning of wider contacts that are more robust to patterning limitations.Type: GrantFiled: January 17, 2023Date of Patent: January 30, 2024Assignee: Intel CorporationInventors: Mark T. Bohr, Tahir Ghani, Nadia M. Rahhal-Orabi, Subhash M. Joshi, Joseph M. Steigerwald, Jason W. Klaus, Jack Hwang, Ryan Mackiewicz

Patent number: 11652045Abstract: An example via contact patterning method includes providing a pattern of alternating trench contacts and gates over a support structure. For each pair of adjacent trench contacts and gates, a trench contact is electrically insulated from an adjacent gate by a dielectric material and/or multiple layers of different dielectric materials, and the gates are recessed with respect to the trench contacts. The method further includes wrapping a protective layer of one or more dielectric materials, and a sacrificial helmet material on top of the trench contacts to protect them during the via contact patterning and etch processes for forming via contacts over one or more gates. Such a method may advantageously allow increasing the edge placement error margin for forming via contacts of metallization stacks.Type: GrantFiled: October 27, 2021Date of Patent: May 16, 2023Assignee: Intel CorporationInventors: Mohit K. Haran, Daniel James Bahr, Deepak S. Rao, Marvin Young Paik, Seungdo An, Debashish Basu, Kilhyun Bang, Jason W. Klaus, Reken Patel, Charles Henry Wallace, James Jeong, Ruth Amy Brain
