Abstract:
A packaging base for semiconductor elements is made of metal powder selected from the group consisting of cupper (Cu), iron (Fe), wolfram (W), molybdenum (Mo), aluminum (Al), indium (In), and gallium (Ga) or from an alloy of combinations thereof. A heat sink is integrally formed by metallurgical injection molding process. A fixing mount and a protection mount are positioned on the heat sink, thereby creating a packaging base structure. The protection mount surrounds the fixing mount for protecting semiconductor elements like laser diode dies. The packaging base structure includes a mounting gap for the purpose of an easy installation of the semiconductor elements. In this way, the reduction of the heat-removal capacity caused by the thermal contact resistance of the conventional configuration can be avoided so that the cooling effect can be enhanced. Meanwhile, the fabrication process is simplified.
