Sensor system
First Claim
1. A system comprising:
- an image sensor structure comprising;
an image layer disposed over a base substrate,a device stack disposed over the image layer,a bond pad disposed in the device stack,a passivation stack disposed over the device stack and the bond pad,an array of nanowells disposed in a top layer of the passivation stack,a through-silicon via (TSV) in electrical contact with the bond pad, the TSV extending through the base substrate, anda redistribution layer (RDL) disposed on a bottom surface of the base substrate, the RDL in electrical contact with the TSV; and
a flow cell disposed upon the top layer of the passivation stack to form a flow channel therebetween;
wherein the flow channel is disposed over the array of nanowells and extends over the bond pad;
wherein the passivation stack is disposed between the flow channel and the bond pad.

Abstract
A system includes an image sensor structure and a flow cell. The image sensor structure includes an image layer disposed over a base substrate. A device stack is disposed over the image layer. A bond pad is disposed in the device stack. A passivation stack is disposed over the device stack and the bond pad. An array of nanowells is disposed in a top layer of the passivation stack. A through-silicon via (TSV) is in electrical contact with the bond pad. The TSV extends through the base substrate. A redistribution layer (RDL) is disposed on a bottom surface of the base substrate. The RDL is in electrical contact with the TSV. The flow cell is disposed upon the top layer of the passivation stack to form a flow channel therebetween. The flow channel is disposed over the array of nanowells and the bond pad.
