ABSTRACT:
A monolithic shielded integrated circuit is formed using a leadframe (11) having electrically isolated flag areas (12 and 13). Semiconductor die are attached to the electrically isolated flag areas (12 and 13). An integral shield is formed on monolithic integrated circuit (23) for protection against radio frequency noise. A molded package (22) is formed around portions of the leadframe (11) thereby encapsulating the integrated circuit (23) and its integral shield.
