Abstract:
1. An ultra-wideband semiconductor device for an ultra-wideband standard for ultra-high-frequency communication, comprising: an ultra-wideband semiconductor chip; an ultra-wideband circuit with passive devices; a multilayer circuit substrate with at least a lower metal layer and an upper metal layer, in which the ultra-wideband circuit is arranged, and wherein the lower metal layer comprises external contact pads on which external contacts are arranged, enabling the semiconductor device to be surface-mounted on a circuit board, wherein the circuit substrate comprises an opening in which the semiconductor chip is arranged face-down such that a rear face of the semiconductor chip forms a coplanar surface with an upper face of the circuit substrate; an antenna operatively coupled to the semiconductor chip via the ultra-wideband circuit and arranged on the coplanar surface above the semiconductor chip and the circuit substrate, wherein an active upper face of the semiconductor chip faces a lower face of the circuit substrate and is operatively coupled via connecting elements to the circuit substrate and to the antenna; and a shield for the ultra-wideband circuit.
