    摘要: A method of reducing contact size in an integrated circuit includes providing an insulating layer over a semiconductor substrate including a plurality of gate structures, creating an aperture extending through the insulating layer and having side walls, providing a spacer on the side walls of the aperture, and providing a contact in the aperture. The lateral sides of the contact abut the spacer. A contact structure is also disclosed in which a spacer separates a contact from a gate structure to avoid charge gain or loss between the contact and gate structure.

    摘要: Multi-metallization level semiconductor devices are formed without degrading a low k dielectric gap fill material due to multiple pre-metallization degassing/outgassing heat treatments. Degradation of the low k material is substantially reduced or eliminated by employing time intervals for heat treatment which are not longer than the longest metal deposition step and temperatures below that which the dielectric material decomposes.

    摘要: In a preferred embodiment, there is disclosed a method of forming a tungsten plug at the via level. A metal line is formed in a top portion of a first insulating layer. A second insulating layer is formed on the first insulating layer and over an exposed surface of the metal line. An etching process is applied to a region of the second insulating layer formed over the exposed surface of the metal line to create a contact hole within the region. The metal line is exposed at the region. A tungsten nitride thin film is deposited over the second insulating layer and the exposed metal line. A blanket tungsten thin film is deposited to fill the contact hole and to form a planar layer successively to the depositing of the tungsten nitride thin film. The tungsten nitride thin film and the blanket tungsten thin film are chemically mechanically polished until the upper surface of the second insulating layer is exposed.
