  • Patent number: 11940734
    Abstract: The inventive concept provides a substrate treating apparatus. The substrate treating apparatus includes a chamber having a treating space therein; a supply line having a first open/close valve installed thereon and configured to supply a treating fluid to the treating space; a heater installed on the supply line and configured to heat the treating fluid; an exhaust line having a second open/close valve installed thereon and configured to exhaust the treating space; and, a controller configured to control the first open/close value and the second open/close valve such that the treating fluid heated is supplied to and exhausted from the treating space before a treating process is performed on a substrate in the treating space.

  • Patent number: 8183683
    Abstract: A semiconductor device is provided. The semiconductor device comprises a semiconductor die having bond pads, each of which consists of a first bond pad made of a material whose ionization tendency is relatively low and a second bond pad made of a material whose ionization tendency is relatively high. The second bond pads function as sacrificial anodes to prevent the occurrence of galvanic corrosion at the interfaces between the first bond pads and conductive wires. In an embodiment, the upper surfaces of the second bond pads are marked instead of those of the first bond pads, which reduces the number of defects in the first bond pads. A method for fabricating the semiconductor device is also provided.
