Summary of the patent applications from SK hynix Inc. on October 5th, 2023

SK hynix Inc. has recently filed several patents related to the manufacturing and design of semiconductor memory devices. These patents cover various aspects of the manufacturing process, device structures, and methods of creating specific components within the devices.

Some notable applications include:

  • A method of manufacturing a semiconductor memory device that involves creating a preliminary source structure and stacked structure, forming a slit through the stacked structure to define recess regions, and adding sacrificial layers to the recess regions before removing the source sacrificial layer and forming a source channel coupling layer.
  • A memory device with a stack structure, main plugs, and a separation pattern that separates the main plugs. The stack structure is divided into two memory blocks by a slit pattern with an elliptical shape.
  • A semiconductor memory device with gate stack structures, dummy and lower vertical channels, select line isolation structures, and upper vertical channels. The select line isolation structures partially penetrate the second gate stack structure and overlap with the dummy vertical channel.
  • A semiconductor device with a lower structure, multiple active layers, bit lines, a word line, and a capping layer containing an air gap separating the bit lines and word lines.
  • A method for creating a semiconductor device that involves creating a stack body, sacrificial vertical structure, etching the stack body to create vertical openings, removing the sacrificial pad, adding an etch stop liner layer, and selectively removing the sacrificial vertical structure.
  • Image sensing devices with phase difference detection pixels and a light shielding pattern that provides a light receiving region along two sides of each pixel.
  • An interface device with two ports for communication with a host and a function manager for assigning different functions to each port.
  • A semiconductor memory device with multiple layers of insulating material, a select line, a core insulating layer, semiconductor patterns, and a gate insulating layer.
  • A semiconductor package with an interposer, heat dissipation layer, semiconductor dies, and a thermally conductive connection part for transferring heat from the stack of semiconductor dies to the heat dissipation layer.
  • A semiconductor memory device with a lower structure, cell and chip guard regions, lower and upper stack structures, and a slit that exposes the etch stop layer in the chip guard region.

Overall, SK hynix Inc. has filed patents that cover a wide range of innovations in the manufacturing and design of semiconductor memory devices. These patents demonstrate the company's commitment to advancing the field and developing new technologies for the industry.
