DEFINITION

Classification: 438/63

Particulate semiconductor component:

(under subclass 57) Process for making a device responsive to electromagnetic radiation wherein the substrate contains particulate semiconductive material.

(1) Note. "Particulate" is defined as a mass of discrete units of matter so small (generally of largest dimension <<1000 microns) that they are not ordinarily handled as individual units, and whose shape and length-to-diameter ratio are such that in the dry state the particles will not hold together as a coherent article without the application of pressure or heat.
