In a method of manufacturing semiconductor wafers, front and back surfaces of the semiconductor wafers are simultaneously polished with a double-side polishing machine that includes: a carrier for accommodating the semiconductor wafer; and an upper press platen and a lower press platen for sandwiching the carrier. The gaming system also includes a display for displaying a randomly selected outcome of the wagering game and a touch-screen input device in association with the display. The RF components and one or more MEMS switch arrays may be integrated in the multi-layer package. The service provided to a group of customers, that group of customers being defined by at least a portion of the unique bit string, may be monitored. The color filter array is a color filter array in which a spatial sampling point is approximately arranged in at least one of +1\xb12 and y=3m\u22122 ) and +1 and y=3m\u22122\xb12 ). The profiled surface ensures that launching of the aircraft is effected smoothly, initially at low speed and then at progressively increasing speed until the aircraft attains take-off speed.
