  • Publication number: 20240138148
    Abstract: A method of forming a three-dimensional (3D) NAND memory device includes: forming a gate line slit through alternating layers of an oxide layer and a conductive material layer, wherein the conductive material layer is further formed on a sidewall and a bottom of the gate line slit; performing a first etch process to remove portions of the conductive material layer from the sidewall and the bottom of the gate line slit and from between adjacent oxide layers, thereby exposing portions of the oxide layer in the gate line slit; removing the exposed portions of the oxide layer on the sidewall of the gate line slit; and performing a second etch process to remove residues of the conductive material layer in the gate line slit.

  • Patent number: 11911342
    Abstract: A connector for connecting a medical injection device, including a barrel and a needle extending from a distal tip of the barrel, to a container including a septum includes an inner deformable cover and an outer rigid cover. The inner deformable cover extends along a cover axis and includes a proximal connection part configured to engage the distal tip of the barrel and a distal portion. The outer rigid cover encloses the inner deformable cover and includes a distal adaptor configured to engage the container. The outer cover is configured so the needle tip extends into the distal adaptor when the proximal connection part of the inner deformable cover engages the distal tip of the barrel. The outer rigid cover is fixed to the inner deformable cover. The inner deformable cover is compressible between a relaxed configuration and a compressed configuration.

  • Patent number: 11911396
    Abstract: Disclosed is use of 5?-androst-3?,5,6?-triol or an analogue, a deuterated compound or a pharmaceutically acceptable salt thereof in the manufacture of a medicament for the treatment of cerebral small vessel disease in a patient. The cerebral small vessel disease is preferably cerebral microbleed. The cerebral microbleed is spontaneous cerebral microbleed, drug-related cerebral microbleed, or traumatic cerebral microbleed. The present invention demonstrates that these compounds significantly enhance the clearance of extravascular hemoglobin, and thus can be used to treat cerebral small vessel disease.

  • Publication number: 20240015973
    Abstract: A method of forming a three-dimensional (3D) NAND memory device includes: forming a gate line slit through a plurality of alternating layers of an oxide layer and a conductive material layer, where the conductive material layer is further formed on a sidewall and a bottom of the gate line slit; performing an ion implantation process to dope at least a portion of the conductive material layer that is on the bottom and/or a portion of the sidewall of the gate line slit; and performing an etch process in the gate line slit to remove the conductive material layer that is weakened by the ion implantation process.
