Abstract: There is provided a gas solution supply apparatus capable of preventing bubbles from being generated in use at a point-of-use even if gas solution to be provided to a point-of-use has a high concentration. The gas solution supply apparatus 1 includes: a gas dissolving unit 4 that dissolves a source gas in a source liquid to produce a first gas solution; a first gas-liquid separator 10 that stores the first gas solution produced and produces a second gas solution through gas-liquid separation of the first gas solution; a pressure reducer 17 that depressurizes the second gas solution produced in the first gas-liquid separator 10; and a second gas-liquid separator 12 that stores the depressurized second gas solution and produces a third gas solution through gas-liquid separation of the second gas solution. The third gas solution is supplied to a point-of-use.

Abstract: A semiconductor device includes a first semiconductor element, a first object, a sealing resin and a covering part. The first semiconductor element includes a first electrode. The first object includes a first surface facing the first electrode. The sealing resin covers the first semiconductor element and the first object. The covering part is interposed between the first electrode and the first surface and contains a material having a higher thermal conductivity than the sealing resin.
