Patent ID: 11942417
Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 8:
9. A package comprising:
a semiconductor die comprising a contact pad on a top surface of the semiconductor die and a sensing region on the top surface of the semiconductor die;
an encapsulant surrounding the semiconductor die and physically contacting the semiconductor die, wherein the top surface of the semiconductor die and a bottom surface of the semiconductor die are free of encapsulant;
a conductive via extending through the encapsulant, the conductive via separated from the semiconductor die by the encapsulant;
a first dielectric layer extending over a top surface of the encapsulant, along a sidewall of the encapsulant, and over the top surface of the semiconductor die, wherein the first dielectric layer has a first opening that exposes the sensing region of the semiconductor die;
a conductive layer over a top surface of the first dielectric layer, the conductive layer extending through the first dielectric layer to contact the conductive via and extending through the first dielectric layer to contact the contact pad; and
a second dielectric layer overlying the conductive layer, wherein the second dielectric layer has a second opening that exposes the sensing region of the semiconductor die through the first opening in the first dielectric layer.
