Disclosed is an apparatus for supplying liquid for use in a plasma disinfection system. A heat sink section is formed on the upper portion of the support section in a wide width extending to the side of the projecting two leads. The sets of symbols include different characteristics or features such that the volatility of the matching game differs depending on which particular set of symbols the player selects for the play of the matching game. An isolation layer is formed on the substrate and over the first gate structure. The surface area ratio between surface drain regions and the well region, which includes the source region, is from 0. The device further includes a cap layer formed on the barrier layer at a side of the electrode, and made of third group III nitride semiconductor containing a mixture of single crystals and polycrystals.
