Abstract:
1. A fluid cooled semiconductor die package, comprising: a package support substrate with a die mounting surface and an opposite package mounting surface, the package support substrate having external connector solder deposits on respective external connector pads of the package mounting surface, wherein the package support substrate has at least one package fluid inlet duct and at least one package fluid outlet duct each providing fluid communication between the die mounting surface and the package mounting surface; a semiconductor die mounted on the die mounting surface of the package support substrate, the semiconductor die having external terminals selectively electrically connected to the external connector pads; an inlet solder deposit soldered to an inlet pad of the package mounting surface, wherein the inlet pad surrounds an entrance of the package fluid inlet duct; and an outlet solder deposit soldered to an outlet pad of the package mounting surface, wherein the outlet pad surrounds an exit of the package fluid inlet duct, wherein each of the external connector solder deposits is formed from a single solder ball, and the inlet solder deposit is formed from at least one solder ball that is the same size as the single solder ball.
