=+26. The relative conductivity of a semiconductor device is determined by the amount of impurity

“doped” into the device during its manufacture.

A silicon diode to be used for a specific purpose requires an average cut-on voltage of .60 V, and if this is not achieved, the amount of impurity must be adjusted. A sample of diodes was selected and the cut-on voltage was determined. The accompanying SAS out-put resulted from a request to test the appropriate hypotheses.
