Abstract
Abstract An electronic module (10) for removing heat from a semiconductor die (41) and a method of making the electronic module (10). The electronic module (10) has a baseplate (11) mated with an isolation structure (23). The isolation structure (23) has three portions: a first portion is bonded to the top surface (12) of the baseplate (11), a second portion is bonded to the bottom surface (13) of the baseplate (11), and a third portion is bonded to a side (14) of the baseplate (11). A semiconductor die (41) is bonded to the first portion of the isolation structure (23) and another semiconductor die (41) is bonded to the second portion of the isolation structure (23). The baseplate (11) has a cavity (20) through which a fluid flows and transports heat away from each semiconductor die (41).
