  • Patent number: 8835259
    Abstract: Provided are a transistor of a semiconductor device and a method for manufacturing the same. A gate induced drain leakage (GIDL) current is reduced by decreasing a work function at an upper portion of a gate electrode, and a threshold voltage of the transistor is maintained by maintaining a work function at a lower portion of the gate electrode at a high level, thereby reducing a leakage current of the transistor and reducing a read time and a write time of the semiconductor device. The transistor of the semiconductor device includes: a recess with a predetermined depth in a semiconductor substrate; a first gate electrode disposed within the recess; and a second gate electrode disposed on the first gate electrode into which ions of one or more of nitrogen (N), oxygen (O), arsenic (As), aluminum (Al), and hydrogen (H) are doped.

    Abstract: The present invention relates to an upstream ozone contact tank for removing residual ozone. The upstream ozone contact tank includes an inlet through which purified raw water flows, at least one contact chamber, at least one reaction chamber, an upstream contact chamber, and an outlet that discharges ozone-treated raw water. Especially, the invention provides an upstream contact chamber between the reaction chamber and outlet, wherein the upstream contact chamber includes carbonaceous filter media mounted on a porous plate. An openable gate unit is installed at the lower part of a panel partitioning a final reaction chamber and the upstream contact chamber and controls flow rate. Additionally, the invention enables upstream flow of the raw water flowing into the upstream contact chamber from the final reaction chamber so that the raw water may pass through the carbonaceous filter media upwardly.
