Abstract:
A method comprising:forming a photoimageable material on a dielectric material overlying a contact point; developing the photoimageable material over an opening area, the photoimageable material over a first portion of the opening area developed to a first extent and the photoimageable material over a second portion of the opening area developed to a lesser second extent; forming an opening in the dielectric material about the opening area to a depth equivalent to the thickness of the dielectric layer less an effective thickness for an opening about a second opening area; removing photoimageable material over the second portion of the opening area; after removing the photoimageable material, forming an opening in the dielectric material to the contact point about the opening area and forming an opening in the dielectric material about the second opening area; and after forming the opening in the dielectric material to the contact point and the opening in the dielectric material about the second opening area, forming an interconnect coupled to the contact point.
