Abstract:
A method of forming a pattern in a low-k dielectric material, comprising:providing a semiconductor substrate having a low-k dielectric material thereover, wherein the semiconductor substrate has an optical alignment pattern supported thereby; providing a mold having a first pattern comprising projections and valleys between the projections wherein, the mold comprises a region through which the optical alignment pattern can be viewed during an alignment of the mold and substrate relative to one another; aligning the mold and substrate relative to one another before the pressing; pressing the low-k dielectric material between the mold and the semiconductor substrate to form a second pattern in the low-k dielectric material, the second pattern being substantially complementary to the first pattern; and removing the mold from over the low-k dielectric material.
