Array substrate and manufacturing method thereof and display device

The invention relates to an array substrate and a manufacturing method thereof and a display device. The array substrate comprises a substrate, common electrodes, multiple rows of grid lines and multiple pixel electrodes, wherein the common electrodes, the multiple rows of grid lines and the multiple pixel electrodes are formed on the substrate; the pixel electrodes and the common electrodes are arranged at different layers; a vertical overlap part exists in each pixel electrode and the corresponding common electrode; and in two pixel electrodes connected to the same row of grid lines, the area of the vertical overlap part of the pixel electrode which is further to the first ends of the grid lines and the corresponding common electrode is smaller than that of the pixel electrode which is nearer the first ends of the grid lines and the corresponding common electrode. According to the array substrate, the leaping voltage of the pixel electrode further to the first ends of the grid lines obtains more compensation than that nearer the first ends of the grid lines, so that the difference between the leaping voltages of two pixel electrodes is reduced; the residual image is reduced. Furthermore, compared with the mode of increasing a gate-source capacitance in the prior art, the array substrate has the advantage that the power consumption of the array substrate can be reduced.

Multilayer ceramic antenna and preparation method thereof

The invention discloses a multilayer ceramic antenna and a preparation method thereof. The ceramic antenna comprises a ceramic medium and multiple layers of radiating conductor belts positioned in the ceramic medium, and is characterized in that the ceramic antenna further comprises peripheral end sealing metal and edge isolating holes, wherein by adopting the edge isolating holes, vertical overlapping parts of the multiple layers of radiating conductor belts protrude from the surface of the ceramic medium; the edge isolating holes are used for isolating adjacent peripheral end sealing metal; and the peripheral end sealing metal is used for interconnecting the multiple layers of radiating conductor belts. The multilayer ceramic antenna disclosed by the invention has the advantages that through the isolating holes and chamfers positioned in appropriate positions of the edge of the periphery of the ceramic medium, the vertical overlapping parts of the multiple layers of radiating conductor belts and the vertical overlapping parts of the multiple layers of radiating conductor belts with an external micro strip feeder line are enabled to protrude from the surface of the ceramic medium and be isolated from each other, and the multiple layers of connectors can be conveniently connected through the end sealing metal, thereby realizing the interconnection among different metal layers under the circumstance that a through-hole is not needed; and besides, a large quantity of ceramic media can be stacked to be edge-punched and chamfered at once.

Trench insulated gate bipolar transistor device and generating method thereof

The invention provides a trench insulated gate bipolar transistor device and a generating method thereof. A relatively thick gate oxide film is formed at the bottom of a trench region through a plasmafilm forming process. Due to the fact that the thickness of the gate oxide film at the bottom of a trench is increased, the consistency of the gate oxide thickness is guaranteed, the defect that a gate oxide layer at the bottom of the trench is easy to break down is eliminated, and the robustness of a gate oxide breakdown voltage is improved. Meanwhile, the area of a gate-drain capacitor is reduced, so that the Miller capacitance is reduced, the switch delay time is shortened, the switch dynamic loss of a device is reduced, and the switch characteristic of the device is improved. Meanwhile, the relatively thick gate oxide film is formed at the bottom of the trench, so that the upper surface of polycrystalline silicon subjected to back etching can be leveled and is slightly higher than thesurface of a silicon wafer of a N-type base region; and higher N+ emitter junction depth can be formed without increasing the injection energy of an N+ emitter and carrying out longer-time high-temperature trap pushing, so that the vertical overlapping area of the gate and the source is reduced, the gate-source capacitance is reduced, and the switch loss of an IGBT is reduced.
