  • Patent number: 11974433
    Abstract: A semiconductor memory device includes a third insulating pattern and a first insulating pattern on a substrate, the third insulating pattern and the first insulating pattern being spaced apart from each other in a first direction that is perpendicular to the substrate such that a bottom surface of the third insulating pattern and a top surface of the first insulating pattern face each other, a gate electrode between the bottom surface of the third insulating pattern and the top surface of the first insulating pattern, and including a first side extending between the bottom surface of the third insulating pattern and the top surface of the first insulating pattern, and a second insulating pattern that protrudes from the first side of the gate electrode by a second width in a second direction, the second direction being different from the first direction.

  • Publication number: 20240087503
    Abstract: A display device includes pixels each including a driving transistor and a light-emitting element, a sensing unit which generates a digital data by receiving a sensing voltage corresponding to a characteristic of a driving transistor from a predetermined pixel among the pixels during a sensing period, and generates sensing data using the digital data, and a timing controller which receives input data from an outside, corrects the input data using the sensing data and generates output data, and the sensing unit generates one sensing data using two or more digital data corresponding to the predetermined pixel.

  • Publication number: 20040124093
    Abstract: The invention relates to several apparatuses and methods for the continuous production of carbon soot with a high content of fullerenes, endohedral metallofullerenes (EMFs), and carbon nanotubes. In addition, the invention relates to anaerobic manipulations of carbon-based compounds. The claimed apparatuses and methods provide optimal conditions during annealing processes. In particular, the rotary shielding block of the present invention can effectively prevent resultant products from exposure to intense ultraviolet radiation associated with vaporization processes.
