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

Claim 15:
16. A method of making a semiconductor package, comprising:
forming a semiconductor die;
covering a metal layer with a substrate, the metal layer configured to carry signals in a 2 GHz to 38 GHz frequency range;
forming a ground shield between the metal layer and the semiconductor die, the ground shield having a recessed area along a perimeter of the ground shield and abutting an empty space in a same horizontal plane as the ground shield, the empty space vertically aligned with a first segment of the metal layer, the ground shield aligned with a second segment of the metal layer more proximal to a center of the semiconductor package than the first segment;
forming a metal seal ring vertically aligned with the ground shield and not vertically aligned with the empty space; and
coupling a metal lid coupled to a top surface of the metal seal ring.
