Publication number: 20220399232Abstract: A vertical layer stack including a bit-line-level dielectric layer and an etch stop dielectric layer can be formed over an array region. Bit-line trenches are formed through the vertical layer stack. Bit-line-trench fill structures are formed in the bit-line trenches. Each of the bit-line-trench fill structures includes a stack of a bit line and a capping dielectric strip. At least one via-level dielectric layer can be formed over the vertical layer stack. A bit-line-contact via cavity can be formed through the at least one via-level dielectric layer and one of the capping dielectric strips. A bit-line-contact via structure formed in the bit-line-contact via cavity includes a stepped bottom surface including a top surface of one of the bit lines, a sidewall segment of the etch stop dielectric layer, and a segment of a top surface of the etch stop dielectric layer.Type: ApplicationFiled: June 11, 2021Publication date: December 15, 2022Inventors: Fumitaka AMANO, Yusuke OSAWA, Kensuke ISHIKAWA, Mitsuteru MUSHIGA, Motoki KAWASAKI, Shinsuke YADA, Masato MIYAMOTO, Syo FUKATA, Takashi KASHIMURA, Shigehiro FUJINO

Patent number: 9779312Abstract: Provided is a system capable of further reducing risk such as a contact between a moving body such as a vehicle and a traffic participant present around the moving body. According to an environment recognition system (1) of the present invention, a database (10) stores each of a plurality of reference symbol strings describing the state of an environmental element constituting each of a plurality of scenes assumed to be around the moving body. A first arithmetic processing element (11) detects a scene around the moving body and generates a symbol string describing the state of the environmental element constituting the detected scene. A second arithmetic processing element (12) evaluates similarity between the symbol string and each of the plurality of reference symbol strings stored in the database (10).Type: GrantFiled: January 27, 2016Date of Patent: October 3, 2017Assignee: HONDA MOTOR CO., LTD.Inventors: Yoshiaki Sakagami, Taku Osada, Kensuke Ishikawa
