  • Patent number: 9941293
    Abstract: Disclosed herein is a 3D memory with a select transistor, and method for fabricating the same. The select transistor may have a conductive floating gate, a conductive control gate, a first dielectric between the conductive floating gate and the conductive control gate, and a second dielectric between a body and the conductive floating gate. In one aspect, a uniform gate dielectric is formed using lateral epitaxial growth in a recess adjacent a crystalline semiconductor select transistor body, followed by forming the gate dielectric from the epitaxial growth. Techniques help to prevent, or at least reduce, a leakage current between the select transistor control gate and the select transistor body and/or the semiconductor substrate below the select transistor. Therefore, select transistors having a substantially uniform threshold voltage, on current, and S-factor are achieved. Also, select transistors have a high on-current and a steep sub-threshold slope.

  • Patent number: 9881811
    Abstract: The present invention provides a TFT substrate manufacturing method and a TFT substrate manufactured with the method. The TFT substrate manufacturing method of the present invention uses a photoresist pattern to serve as a shielding mask to allow a metal layer to be directly oxidized, through the anodic oxidation technology, into a gate insulation layer or a passivation layer, and at the same time, forming electrode patterns of gate or source/drain. The entire operation can be conducted in room temperature and is applicable to a flexible substrate that is not resistant to high temperatures without the involvement of expensive high temperature facility, such as chemical vapor deposition, so as to greatly reduce the operation cost of manufacturing a flexible display device. The TFT substrate manufactured with the present invention shows excellent electrical characteristics and is suitable for a flexible display device.
