DEFINITION

Classification: 438/130

Rendering selected devices operable or inoperable:

(under subclass 128) Process wherein selected devices located on a semiconductive substrate are electrically completed or electrically shorted so as to be rendered operable or inoperable.

(1) Note. Adjusting an operating characteristic (e.g., threshold voltage) of selected devices so as to render them operational yet nonresponsive to the intended operating voltage is specifically excluded from herein.
