Patent ID: 7381613

Claim:
A method of fabricating a semiconductor device, comprising: providing an intermediate structure having an insulating layer formed on top; forming a group of cup-shaped openings in the insulating layer; depositing a first conducting material over the structure such that the first conducting material substantially coats the inside of the cup-shaped openings; removing excess portions of the first conducting material from a top surface of the structure; forming a trench in the insulating layer, wherein the trench extends between the cup-shaped openings of the group and crosses each of the cup-shaped openings of the group, and wherein the trench forms a recess in the first conducting material where the trench crosses the cup-shaped openings; depositing a dielectric material over the structure such that the dielectric material substantially coats the inside of the trench and substantially coats exposed surfaces of the first conducting material; depositing a second conducting material over the structure such that the second conducting material substantially coats the inside of the trench and substantially coats the exposed surfaces of the dielectric material; and removing excess portions of the second conducting material from a top surface of the structure.
