The die-pad has a base portion (202) resting on the assembly surface, an upper portion (204) on the base portion extending laterally from the base portion, and a support arm (208) extending from and supporting the upper portion of die-pad. A semiconductor die (206) is wirebonded (504) to a top surface of the upper portion of the die-pad. The semiconductor die is wirebonded (506) to the one or more lead-pads (210). The semiconductor die and leadframe are encased (508) in a package material (802). The package material fills a space between the upper portion of the die-pad and the assembly surface.
