  • 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: 10906283
    Abstract: A wafer bonding apparatus including: a lower chuck to which a lower wafer is secured at a peripheral portion of the lower chuck; an upper chuck to which an upper wafer is secured; a bonding initiator for pressuring a central portion of the upper wafer until the central portion of the upper wafer reaches a central portion of the lower wafer, thereby initiating a bonding process of the upper and the lower wafers by deforming the upper wafer; and a bonding controller for controlling a bonding speed between a peripheral portion of the upper wafer and a peripheral portion of the lower wafer such that the upper wafer becomes un-deformed prior to bonding the peripheral portion of the upper wafer and the peripheral portion of the lower wafer.

  • Patent number: 10833047
    Abstract: A substrate bonding apparatus includes a lower chuck, an upper chuck, an electric actuator on a central portion of the upper chuck, a pressure sensor, and a controller. The lower chuck may support a lower substrate, the upper chuck may face the lower chuck such that a lower surface of the upper chuck faces the upper surface of the lower chuck, and the upper chuck may support an upper substrate. The electric actuator may lower a bonding pin through the upper chuck to apply a pressure to the upper substrate supported on the upper chuck. The pressure sensor may be below the lower substrate supported on the lower chuck. The pressure sensor may sense a lowering pressure applied by the bonding pin to the pressure sensor in real time. The controller may control the lowering pressure applied by the bonding pin.
