A method for operating a cooling system for a vehicle, for example a rail vehicle, may include circulating a coolant in a first cooling circuit and in a second cooling circuit. A first heat source to be cooled may be arranged in the first cooling circuit and a second heat source to be cooled may be arranged in the second cooling circuit. The coolant may be circulated by pumping the coolant in the first cooling circuit via a first pumping device, and pumping the coolant in the second coolant circuit via a second pumping device. The first pumping device and the second pumping device may each be operated in a normal mode. The method may further include cooling the coolant via at least one cooling element arranged in at least one of the first cooling circuit and the second cooling circuit.

Failure analysis and recycle of a semiconductor device are facilitated, and a production efficiency of the semiconductor device is improved. An exterior includes an inner space and an inner surface surrounding the inner space. A semiconductor chip is housed in the inner space and mounted on the inner surface. A first sealing material fills the inner space, is disposed on the inner surface to be overlapped on the semiconductor chip, and is made up of silicone gel. A waterproof water-repellent layer is housed in the inner space, disposed on the inner surface to be overlapped on the semiconductor chip and the first sealing material, and made up of fluorine-series resin or silicone-series resin. A second sealing material fills the inner space, is disposed on the inner surface to be overlapped on the semiconductor chip, the first sealing material, and the waterproof water-repellent layer, and is made up of silicone gel.
