Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A method comprising:
attaching a semiconductor die to a carrier;
encapsulating the semiconductor die in a molding compound;
depositing a photo-sensitive material over the semiconductor die and the molding compound;
patterning the photo-sensitive material, wherein patterning the photo-sensitive material comprises:
exposing the photo-sensitive material to a patterned energy source using an photomask, wherein an outer perimeter the photomask is at least as large as an outer perimeter of the carrier, and wherein an entirety of a top surface of the photo-sensitive material is exposed to the patterned energy source simultaneously; and
after exposing the photo-sensitive material, developing the photo-sensitive material to define a plurality of openings through the photo-sensitive material; and

plating a metallization pattern in the plurality of openings.
