61.   The plates are used to produce integrated circuits on silicon wafers.

62.   The profit gain comes from higher sales of silicon wafers.

63.   The second transformation is a change in the diameter of the silicon wafers from which chips are made.

64.   The silicon wafers are often shielded while they are treated with chemicals.

65.   The transponder is made up of silicon wafers, circuits and sensors that together are about the size of a quarter.
