Abstract
Device leads on a packaged integrated circuit are protected during a decapsulation process. A composite material such as wax is applied to coat the leads. At least a portion of a package containing the integrated circuit is then removed while the composite material is coating the leads, the coated leads being protected from fumes associated with the decapsulation process and less susceptible to deformation during handling. The composite material is then removed from the leads after the portion of the package is removed from the packaged device.
