  • Patent number: 11967462
    Abstract: A capacitor component includes a body, including a dielectric layer and an internal electrode layer, and an external electrode disposed on the body and connected to the internal electrode layer. At least one hole is formed in the internal electrode layer, and a region, containing at least one selected from the group consisting of indium (In) and tin (Sn), is disposed in the hole. A method of manufacturing a capacitor component includes forming a dielectric green sheet, forming a conductive thin film, including a first conductive material and a second conductive material, on the dielectric green sheet, and sintering the conductive thin film to form an internal electrode layer. The internal electrode layer includes the first conductive material, and a region, including the second conductive material, is formed in the internal electrode layer.

  • Patent number: 11961775
    Abstract: In one example, a semiconductor device can comprise a substrate, a device stack, first and second internal interconnects, and an encapsulant. The substrate can comprise a first and second substrate sides opposite each other, a substrate outer sidewall between the first substrate side and the second substrate side, and a substrate inner sidewall defining a cavity between the first substrate side and the second substrate side. The device stack can be in the cavity and can comprise a first electronic device, and a second electronic device stacked on the first electronic device. The first internal interconnect can be coupled to the substrate and the device stack. The encapsulant can cover the substrate inner sidewall and the device stack and can fill the cavity. Other examples and related methods are disclosed herein.

  • Patent number: 10937548
    Abstract: A method of improving data sets, for example, of patients, each being characterized by relatively low-cost medical data, identifies those patients where the acquisition of higher cost medical data would best inform an estimate of the higher cost medical data for the remaining patients. In this way scarce medical resources can be more efficiently applied in characterizing a potential patient pool, for example, for a clinical trial when resources are not available for extensive medical characterization of each trial participant.

  • Patent number: 6869476
    Abstract: Disclosed herein is a waterproof admixture composition for concrete which is added to fabricate concrete having excellent anti-corrosive performance. The waterproof admixture composition can protect reinforcing steel bars against oxidation in the presence of salt, thereby ensuring excellent anti-corrosive performance and thus greatly improving the durability of reinforced concrete even in salt-damaged areas and corrosive environments and the like by inhibiting the corrosion of the reinforced concrete. The waterproof admixture composition comprises fly ash and silica fume as artificial pozzolan activators, a redispersible powders resin, a higher fatty acid-based metal salt and a high performance water-reducing agent wherein the composition further comprises 18 to 34% by weight of an inorganic salt and 1 to 5% by weight of tannin as an antioxidant, based on the total weight of the composition.
