Abstract

Devices which utilize charge to store information can be strongly affected by the absorption of alpha particles in the active areas. The alpha particles arise from natural sources which may be impurities package materials or may even be constituents of the device itself. The alpha particles generate large quantities of electron-hole pairs which supply the charge that leads to errors. An alpha particle detector on the device can detect events which are indicative of errors.
