Patent ID: 11881460
Assignee: TEXAS INSTRUMENTS INCORPORATED
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 8:
9. A method of making a semiconductor package, comprising:
covering first and second metal layers with a ceramic substrate, the first metal layer configured to carry signals at least in a 20 GHz to 28 GHz frequency range;
positioning a semiconductor die above the first and second metal layers and coupling the semiconductor die to the first metal layer;
positioning a ground shield in a horizontal plane between the semiconductor die and the first metal layer, the ground shield including an orifice above a portion of the first metal layer;
coupling a metal seal ring to a top surface of the ceramic substrate, the metal seal ring having a segment that is vertically aligned with a segment of the ground shield, wherein the segment of the ground shield is between the orifice of the ground shield and a horizontal center of the ground shield; and
coupling a metal lid to a top surface of the metal seal ring.
