Abstract:
1. A multichip circuit module having a main circuit board, at least one carrier substrate mounted on the main circuit board and which is in electrical contact with the main circuit board, and at least one semiconductor chip on the carrier substrate which is in electrical contact with the carrier substrate, wherein the carrier substrate has at least one cavity on a mounting surface to accommodate said at least one semiconductor chip, the carrier substrate having a plurality of layers with conductor tracks extending transversely through said plurality of layers and terminating in conductor contacts on said mounting surface, connecting contacts for associated bumps of said at least one semiconductor chip are provided in said at least one cavity, the at least one semiconductor chip being mounted on the connecting contacts by using the associated bumps in a flip-chip technique, and the mounting surface of the carrier substrate being applied to a contact surface of the main circuit board via a filling material that provides i) a heat dissipation path from said at least one semiconductor chip in said at least one cavity to said circuit board and ii) electrical connection between said conductor contacts and corresponding contacts on said circuit board, without enclosing the connecting contacts and bumps.
