In one embodiment, a device for controlling flow of water from a subterranean formation into a production well may include a flow control member formed from a shape-conforming material and a hydrophilic polymer disposed within the shape-conforming member in an amount sufficient to cause the flow control member to restrict flow of water therethrough. An exterior cylindrical surface and an interior cylindrical surface extend between the first face and the second face. The semiconductor device further comprises a mold resin portion for sealing the at least one semiconductor chips on the wiring substrate portion. A pair of lasers is used to generate optical light beams that are directed at the sensor particles after the particles have been dispersed.
