A deck of rock, paper, scissors playing cards and methods of play therewith are disclosed. Processing conditions of the laser beam are laser frequency in the range of 7500-35000 Hz, current in the range of 14-17 A, power in the range of 25-45 W, moving speed in the range of 5-55 Msec, and process route as an ellipse to thereby form various predetermined colors. The substantially inversely-dished cover member 14 is mounted on the top of the bearing plate 12, and it not only covers the plural intake ports 12a, but also forms a sealed space S between the cover member and the bearing plate 12, and is further provided with an introducing opening 14a larger than the intake port 12a at the center top of the cover member 14. A time-zero test of the latch stability margin is performed by setting a logic state at the storage nodes, then programming the state into the ferroelectric capacitors by polarization.
