Multiple die paddle leadframe and semiconductor device package

Abstract

A leadframe and semiconductor device package with multiple semiconductor device die paddles for accepting multiple semiconductor devices is disclosed, wherein the leadframe increases semiconductor device density and reduces cost by integrating the multiple dies into a semiconductor device package with a relatively small footprint. The leadframe may include at least one full-metal die paddle and at least one reduced-metal die paddle, which may form a unified or hybrid die paddle. The leadframe may enable electrical coupling of multiple semiconductor devices to a common leadfinger and/or die paddle, where internal leadfingers coupled to the common leadfingers and/or die paddles may receive the electrical coupling means from the semiconductor device. Surfaces of one or more die paddles of the leadframe may be exposed to the outside of the semiconductor device package to enable electrical testing of and/or provide heat dissipation from one or more of the semiconductor devices attached to the leadframe.
