  • Patent number: 11966006
    Abstract: A cable detection system for detecting an end of a cable having a plurality of exposed different sections includes an illumination device and a camera. The illumination device emits an illuminating light to the end of the cable. The illumination device simultaneously emits a parallel light and a diffuse light to the end of the cable. The camera captures an image of the end of the cable. The parallel light sharpens a boundary between the different sections of the cable in the image, and the diffuse light clarifies a surface of the different sections in the image.

  • Publication number: 20240099003
    Abstract: A method for forming 3-dimensional vertical NOR-type memory string arrays uses damascene local bit lines is provided. The method of the present invention also avoids ribboning by etching local word lines in two steps. By etching the local word lines in two steps, the aspect ratio in the patterning and etching of stack of local word lines (“word line stacks”) is reduced, which improves the structural stability of the word line stacks.

  • Patent number: 11917821
    Abstract: In the highly efficient fabrication processes for HNOR arrays provided herein, the channel regions of the storage transistors in the HNOR arrays are protected by a protective layer after deposition until the subsequent deposition of a charge-trapping material before forming local word lines. Both the silicon for the channel regions and the protective material may be deposited in amorphous form and are subsequently crystallized in an anneal step. The protective material may be silicon boron, silicon carbon or silicon germanium. The protective material induces greater grain boundaries in the crystallized silicon in the channel regions, thereby providing greater charge carrier mobility, greater conductivity and greater current densities.

  • Patent number: 11610909
    Abstract: A process forms thin-film storage transistors (e.g., HNOR devices) with improved channel regions by conformally depositing a thin channel layer in a cavity bordering a source region and a drain region, such that a portion of the channel material abuts by junction contact the source region and another portion of the channel layer abut by junction contact the drain region. The cavity is also bordered by a storage layer. In one form of the process, the channel region is formed before the storage layer is formed. In another form of the storage layer is formed before the channel region is formed.
