Publication number: 20240053879Abstract: An object drag method includes a first terminal that displays an object on a display of the first terminal. The first terminal receives a drag operation from a user. The drag operation initiates a drag for the object. The first terminal displays, on the display of the first terminal in response to the drag operation, an animation in which the object moves with the drag operation. The first terminal sends drag data to a second terminal after determining that a drag intent of the user is a cross-device drag.

Patent number: 11742247Abstract: A method of performing epitaxial growth of a source and drain on levels of a complementary field effect transistor (CFET) is provided. The method includes depositing a first blocking material in a vertical channel of an unfinished CFET structure, oxidizing silicon at a surface of an upper level of the CFET to provide one or more SiO2 protective layers, etching away a portion of silicon from a lower level of the CFET to form a lateral recess that is exposed to the vertical channel, and performing silicon epitaxial growth in the lower level of the unfinished CFET structure. Further, after the silicon epitaxial growth on the lower level, the method includes depositing a second blocking material in the vertical channel to cover at least a portion of the silicon epitaxial growth in the lower level, removing the SiO2 protective layer, and performing epitaxial growth on the upper level.Type: GrantFiled: July 9, 2021Date of Patent: August 29, 2023Assignee: Synopsys, Inc.Inventors: Xi-Wei Lin, Victor Moroz

Patent number: 11710634Abstract: A method for forming ultra-high density integrated circuitry, such as for a 6T SRAM, for example, is provided. The method involves applying double patterning litho-etch litho-etch (LELE) and using a spacer process to shrink the critical dimension of features. To improve process margins, the method implements a double-patterning technique by modifying the layout and splitting cross-coupling straps into two colors (e.g., each color corresponds to a mask-etch process). In addition, a spacer process is implemented to shrink feature size and increase the metal-to-metal spacing between the two cross-coupling straps, in order to improve process margin and electrical performance. This is achieved by depositing a spacer layer over an opening in a hardmask, followed by spacer etch back. The opening is thus shrunk by the amount of spacer thickness. The strap-to-strap spacing may then be increased by twice the amount of spacer thickness.Type: GrantFiled: July 9, 2021Date of Patent: July 25, 2023Assignee: Synopsys, Inc.Inventors: Xi-Wei Lin, Victor Moroz

Patent number: 11614177Abstract: A check valve includes a housing defining an inlet, an outlet, a passage between the inlet and outlet, and a sealing surface along the passage. A piston member is disposed about a longitudinal axis and has a sealing face disposed perpendicular to the longitudinal axis and a circular groove defined therein extending inward from the sealing face. An O-ring is disposed in the groove. A biasing member exerts a biasing force on the piston and thus forces the O-ring into sealing engagement with the sealing surface of the housing. The piston member is moveable from a first position in which the O-ring is sealingly engaged with the sealing surface of the housing and thus the outlet is sealed from the inlet, and a second position in which the O-ring is spaced from the sealing surface of the housing and thus the outlet is not sealed from the inlet.Type: GrantFiled: August 16, 2021Date of Patent: March 28, 2023Assignee: MUELLER REFRIGERATION, LLCInventors: Mark Bornand, Shi Xi Wei
