Abstract: A high-voltage semiconductor device structure is provided. The high-voltage semiconductor device structure includes a semiconductor substrate, a source ring in the semiconductor substrate, and a drain region in the semiconductor substrate. The high-voltage semiconductor device structure also includes a doped ring surrounding sides and a bottom of the source ring and a well region surrounding sides and bottoms of the drain region and the doped ring. The well region has a conductivity type opposite to that of the doped ring. The high-voltage semiconductor device structure further includes a conductor electrically connected to the drain region and extending over and across a periphery of the well region. In addition, the high-voltage semiconductor device structure includes a shielding element ring between the conductor and the semiconductor substrate. The shielding element ring extends over and across the periphery of the well region.

Abstract: A water cleaner comprises: a filtering canister having a plurality of filtering holes formed through the canister and made of oxidation-reduction alloy for filtering off chlorine and other hazardous materials contained in the water when passing through the filtering holes formed through the canister; and a functional water-treatment material filled in the canister for killing bacteria or fungi, for removing pollutants, and for removing odor in the water for cleaning water in a water tank or reservoir.
