A heat sink with a built-in heat pipe for semiconductor package is disclosed. A method of forming a non-volatile resistance variable device includes forming a chalcogenide material over a semiconductor substrate. The intersection of the airfoil and the endwall may include a fillet for additional strength at the connection. A means for selectively applying electrical power has at least a first selectable mode in which the means applies power to the first lighting unit whereby a first light output pattern is emitted, and a second selectable mode in which the means applies power to the second lighting unit whereby a second light output pattern is emitted. The fishing tackle holder may also include eyelets on the side of the barrel sleeve, with a securing cord to hold the fishing rod so that a fish will not pull the fishing rod out of the barrel sleeve.
