Abstract
Recently, there have been increasing demands for the reduction in size and weight of mobile computing/communication terminals as well as the elongation of the use time of the internal batteries. This invention alters the assembling structure of power MOSFET for reducing the on-state resistance and improving the production efficiency. This semiconductor device includes a lower frame having a header for fixing a semiconductor chip and corresponding external leads , a semiconductor chip fixed on the header, an upper frame having a connection electrode fixed on a current passage electrode formed on the top face of the semiconductor chip and the corresponding leads , and a resin mold . This two-frame configuration provides extremely low on-state resistance and good production efficiency.
