Claim:
1. An image sensor package comprising: an image sensor die having an active side surface, a backside surface opposite to the active side surface, a die body portion, a terrace portion thinner than the die body portion, and a bonding pad disposed on the active side surface; a through via penetrating the terrace portion and being electrically connected to the bonding pad; a first dielectric layer disposed between the through via and the terrace portion, the first dielectric layer covering backside surfaces of the die body portion and the terrace portion; a redistribution line disposed on the first dielectric layer and electrically connected to the through via, the redistribution line extending over a portion of the first dielectric layer on the backside surface of the terrace portion; a second dielectric layer disposed on the first dielectric layer, the second dielectric layer covering the redistribution line and covering an outer sidewall between the active side surface and a backside surface of the terrace portion, an optical lid over the active side surface of the image sensor die; and a dam-like support structure attached between the optical lid and the active side surface of the terrace portion, wherein the dam-like support structure includes a groove in an edge portion of an interface between the dam-like support structure and the active side surface of the terrace portion, wherein the second dielectric layer extends from the outer sidewall of the terrace portion into the groove to cover the edge portion of the interface, and wherein the active side surface includes an image sensor device region wherein the active side surface includes an image sensor device region.
