Claim 0:
1. A structure comprising:
a first integrated circuit die, the first integrated circuit die comprising active devices;
a second integrated circuit die over the first integrated circuit die, the second integrated circuit die comprising active devices and a front side and a backside, the front side of the second integrated circuit die having die connectors, the backside of the second integrated circuit die being free from die connectors, the backside of the second integrated circuit die being coupled to and facing a front side of the first integrated circuit die;
an encapsulant laterally surrounding the second integrated circuit die;
a first conductive via extending through the encapsulant, the first conductive via being electrically coupled to the first integrated circuit die, the first conductive via comprising:
a first portion over the first integrated circuit die, the first portion having a first width, the first width being measured in a first direction, the first direction being parallel to a major surface of the first integrated circuit die; and
a second portion over the first portion, the second portion having a second width, the second width being measured in the first direction, the second width being less than the first width.
