  • Patent number: 10431567
    Abstract: The present invention is directed to leadless LED packages and LED displays utilizing white ceramic casings and thin/low profile packages with improved color mixing and structural integrity. In some embodiments, the improved color mixing is provided, in part, by the white ceramic package casing, which can help reflect light emitted from each LED in many directions away from the device. The non-linear arrangement of the LEDs can also contribute to improved color-mixing. The improved structural integrity can be provided by various features in the bond pads that cooperate with the casing for a stronger package structure. Moreover, in some embodiments the thinness/low profile of each package is attributed to its leadless structure, with the bond pads and electrodes electrically connected via through-holes.

  • Patent number: 10424607
    Abstract: A manufacturing method of a TFT substrate uses a top gate structure and the entire process can be completely done with seven masks. The number of masks used is reduced. The manufacturing process of a TFT substrate is simplified. Product yield can be increased to effectively improve productivity. Heavy and light ion doping can be simultaneously achieved with one single doping operation so that manufacturing cost can be reduced. By subjecting two ends of a semiconductor pattern to heavy ion doping to form a source electrode and a drain electrode, the manufacturing steps can be reduced and the source electrode and the drain electrode so formed do not need to extend through a via hole formed in an interlayer dielectric layer to contact the two ends of the active layer thereby effectively reducing contact resistance and improving product yield. Also provided is a TFT substrate manufactured with the method.

  • Patent number: 10381372
    Abstract: Void formation in tungsten lines in a three-dimensional memory device can be prevented by providing polycrystalline aluminum oxide liners in portions of lateral recesses that are laterally spaced from backside trenches by a distance grater than a predefined lateral offset distance. Tungsten nucleates on the polycrystalline aluminum oxide liners prior to nucleating on a metallic liner layer. Thus, tungsten layers can be deposited from the center portion of each backside recess, and the growth of tungsten can proceed toward the backside trenches. By forming the tungsten layers without voids, structural integrity of the three-dimensional memory device can be enhanced.
