Patent number: 10586860Abstract: In conjunction with a replacement metal gate (RMG) process for forming a fin field effect transistor (FinFET), gate isolation methods and associated structures leverage the formation of distinct narrow and wide gate cut regions in a sacrificial gate. The formation of a narrow gate cut between closely-spaced fins can decrease the extent of etch damage to interlayer dielectric layers located adjacent to the narrow gate cut by delaying the deposition of such dielectric layers until after formation of the narrow gate cut opening. The methods and resulting structures also decrease the propensity for short circuits between later-formed, adjacent gates.Type: GrantFiled: May 3, 2018Date of Patent: March 10, 2020Assignee: GLOBALFOUNDRIES INC.Inventors: Jiehui Shu, Laertis Economikos, Xusheng Wu, John Zhang, Haigou Huang, Hui Zhan, Tao Han, Haiting Wang, Jinping Liu, Hui Zang

Publication number: 20200029966Abstract: A surgical stapling device includes an anvil having a tissue engaging surface, a cartridge assembly including a staple cartridge, a firing mechanism for ejecting staples from the staple cartridge, and an actuator or lever that is configured to move the anvil and the cartridge assembly between spaced and clamped positions. The staple cartridge includes a plurality of rows of pushers that extend longitudinally within the staple cartridge and support the staples. In embodiments, the distance between the pushers and the tissue engaging surface of the anvil in at least one of the plurality of rows of pushers changes to compensate for an increase in outward deflection of the anvil in relation to the cartridge assembly along the longitudinal axis in the distal direction. In some embodiments, the distance between the pushers and the tissue engaging surface of the anvil in at least one of the plurality of rows of pushers is smaller at the distal portion of the staple cartridge than at the proximal portion.Type: ApplicationFiled: March 9, 2017Publication date: January 30, 2020Inventors: Hui Zhan, Xiao Zhou
