Patent ID: 11870130
Assignee: INFINEON TECHNOLOGIES AG
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 7:
8. A method of using a semiconductor device comprising: a semiconductor die comprising a radio frequency (RF) circuit; a first dielectric layer disposed over a first surface of the semiconductor die; an antenna layer disposed over a surface of the first dielectric layer; and an antenna feeding structure coupling the antenna layer to the RF circuit of the semiconductor die, wherein the semiconductor die comprises an opening, and the antenna feeding structure comprises: a first portion comprising a first via arranged within the opening of the semiconductor die and extending to the first surface of the semiconductor die, a second portion comprising a second via arranged through the first dielectric layer and extending from the first surface of the semiconductor die to the antenna layer, and a third portion comprising a planar conductive feature disposed on the first surface of the semiconductor die, the third portion conductively connecting the first portion to the second portion, the method comprising:
generating a first RF signal using the RF circuit of the semiconductor die; and
coupling the first RF signal to the antenna layer via the antenna feeding structure.
