.~ Including atomic particle or radiant energy impinging on a semiconductor
DEFINITION
Classification: 330/308
Including atomic particle or radiant energy impinging on a semiconductor:
(under subclass 250) Subject matter in which the amplifying device semiconductor body is subjected to radiant energy which may be in the form of light, free (unrestrained) electromagnetic energy, gamma rays, etc.., or atomic particle bombardment, such as alpha or beta rays, etc..
(1) Note. If a claimed preferred embodiment of a patent application includes details of means to apply a variable electrical signal to an IC amplifying device, or details of
means to utilize the output of an IC amplifying device, that application is properly classified elsewhere in this class (330).
(2) Note. If, however, a claimed preferred embodiment of a patent application is limited to details of an IC amplifying device without details of the input or output (utilization) means, or the input or output (utilization) means are recited in name only, then the application is properly classified elsewhere outside this class.

4, for maser-type amplifying device which may involve a semiconductor.
5, for solid element wave propagating amplifying devices involving coupling or activation by electromagnetic wave energy applied through wave energy constraining wave propagating means, such as by wave guide.
307, for a claimed preferred embodiment of a patent application includes details of means to apply a variable electrical signal to an IC amplifying device, or details of means to utilize the output of an IC amplifying device. SEE OR SEARCH CLASS
