DEFINITION

Classification: 438/22

MAKING DEVICE OR CIRCUIT EMISSIVE OF NONELECTRICAL SIGNAL:

(under the class definition) Process for making a semiconductor electrical device or circuit which is emissive of a nonelectrical output during operation.

(1) Note. The nonelectrical signal serving as input stimulus to the device or circuit may be described as an information carrying wave.
