Patent ID: 11916007
Assignee: INFINEON TECHNOLOGIES AG
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A semiconductor device comprising:
a substrate comprising an antenna and a conductive feature;
an integrated circuit (IC) die attached to the substrate and comprising a radio frequency (RF) circuit; and
a flexible circuit integrated with the substrate, wherein the flexible circuit is configured to be bendable at an angle of ninety degrees, wherein the substrate comprises a topmost metal layer contacting and extending along a topmost surface of the substrate distal from the IC die, wherein the topmost metal layer comprises the antenna, wherein the topmost metal layer is disposed between the flexible circuit and the IC die, wherein the IC die is disposed outside of the flexible circuit and outside of the substrate, wherein the flexible circuit is electrically coupled to the IC die and the substrate, a first portion of the flexible circuit being disposed between opposing sidewalls of the substrate, a second portion of the flexible circuit extending beyond the opposing sidewalls of the substrate, the second portion of the flexible circuit comprising an electrical connector at a distal end, wherein the first portion of the flexible circuit has an opening, wherein the antenna of the substrate is exposed by the opening.
