ABSTRACT:
A dense semiconductor flip-chip device assembly is provided with a heat sink/spreading/dissipating member that is formed as a paddle of a metallic paddle frame in a strip of paddle frames. Semiconductor dice are bonded to the paddles by, e.g., conventional semiconductor die attachment methods, enabling bump attachment and testing to be conducted before detachment from the paddle frame strip.
