Method for manufacturing a rigid power module with a layer that is electrically insulating and conducts well thermally and has been deposited as a coating, the structure having sprayed-on particles that are fused to each other, of at least one material that is electrically insulating and conducts well thermally, having the following steps: manufacturing a one-piece lead frame; populating the lead frame with semiconductor devices, possible passive components, and bonding corresponding connections, inserting the thus populated lead frame into a compression mold so that accessibility of part areas of the lead frame is ensured, pressing a thermosetting compression molding compound into the mold while enclosing the populated lead frame, coating the underside of the thus populated lead frame by thermal spraying in at least the electrically conducting areas and overlapping also the predominant areas of the spaces, filled with mold compound.
