Abstract

We report a new method for the determination of ion-implanted dose and uniformity of n-type and p-type dopants in GaAs. The technique, employing thermal waves, is noncontact and nondestructive and therefore particularly attractive for monitoring production wafers for GaAs IC production. We demonstrate dose measurements over the 10¹² -10¹⁵ ions/cm² range, contour mapping of implanted dose on a GaAs wafer, and dose measurements on discrete circuit elements of micron spatial scale on a GaAs FET.
