A fluorocarbon layer is formed on a silicon substrate that is a to-be-processed substrate. The method includes calculating system parameters associated with one or more of a desired frequency a desired duty cycle, and a desired phase difference between antennas for a transmitter, and initializing a counter with a value based on the system parameters. The reel strip, buttons on the machine, a player tracking card, andor a gaming machine credit ticket may each comprise alterable film for displaying a plurality of indicia, including images, text, and other information.
