A method for creating a hole in a semiconductor wafer includes forming a
hard mask over a dielectric layer, the hard mask including a solid
portion and a first opening. A patterning layer is provided over the hard
mask, the patterning layer including second and third openings. The
second opening of the patterning layer aligns with the first opening of
the hard mask and the third opening of the patterning layer aligns with
the solid portion of the hard mask. The hole is created in the dielectric
layer using the second opening of the patterning layer and the first
opening of the hard mask.
