摘要: A method of forming overlapping contacts in a semiconductor device includes forming a first contact in a dielectric layer; etching the dielectric layer to form a recess adjacent to the first contact and removing a top portion of the first contact while etching the dielectric layer, wherein a bottom portion of the first contact remains in the dielectric layer after the recess is formed in the dielectric layer; and forming a second contact in the recess adjacent to the bottom portion of the first contact and on top of a top surface of the bottom portion of the first contact.
