20220043314 | SEMICONDUCTOR DEVICE AND MANUFACTURING METHOD THEREOF - An object is to provide a semiconductor device having a structure in which parasitic capacitance between wirings can be efficiently reduced. In a bottom gate thin film transistor using an oxide semiconductor layer, an oxide insulating layer used as a channel protection layer is formed above and in contact with part of the oxide semiconductor layer overlapping with a gate electrode layer, and at the same time an oxide insulating layer covering a peripheral portion (including a side surface) of the stacked oxide semiconductor layer is formed. Further, a source electrode layer and a drain electrode layer are formed in a manner such that they do not overlap with the channel protection layer. Thus, a structure in which an insulating layer over the source electrode layer and the drain electrode layer is in contact with the oxide semiconductor layer is provided. | 2022-02-10 |
20220043315 | DISPLAY SUBSTRATE, DISPLAY PANEL, AND ELECTRONIC DEVICE - A display substrate is provided, including: a base substrate; a display area, and a peripheral area surrounding the display area on the base substrate, where a dummy pixel unit and a dummy data line are located in the peripheral area. The dummy pixel unit includes a thin film transistor including a first electrode and a second electrode. The first electrode is one of a source electrode and a drain electrode and is electrically connected to the dummy data line, and the second electrode is another of the source electrode and the drain electrode and includes a first portion and a second portion separated by a first opening. A display panel including the display substrate and an electronic device including the display substrate or the display panel are further provided. | 2022-02-10 |
