Embodiments of the present invention provide a microelectronic structure including a conductive element contacting a bulk semiconductor region of a substrate, the bulk semiconductor region being separated from a semiconductor-on-insulator (“SOI”) layer of the substrate by a buried dielectric layer. The microelectronic structure includes a trench isolation region overlying the buried dielectric layer, the trench isolation region sharing an edge with the SOI layer; a conformal layer overlying the trench isolation region, the conformal layer having a top surface and an opening defining a wall extending from the top surface towards the trench isolation region, the top surface including a lip portion adjacent to the wall; a dielectric layer overlying the top surface of the conformal layer; and a conductive element in conductive communication with the bulk semiconductor region, the conductive element consisting essentially of at least one of a semiconductor, a metal, and a conductive compound of a metal, and extending through the dielectric layer, the opening in the conformal layer, the trench isolation region, and the buried dielectric layer, and the conductive element contacting the lip portion.
摘要:
A method of fabricating a gate structure in a metal oxide semiconductor field effect transistor (MOSFET) and the structure thereof is provided. The MOSFET may be n-doped or p-doped. The gate structure, disposed on a substrate, includes a plurality of gates. Each of the plurality of gates is separated by a vertical space from an adjacent gate. The method deposits at least one dual-layer liner over the gate structure filling each vertical space. The dual-layer liner includes at least two thin high density plasma (HDP) films. The deposition of both HDP films occurs in a single HDP chemical vapor deposition (CVD) process. The dual-layer liner has properties conducive for coupling with plasma enhanced chemical vapor deposition (PECVD) films to form tri-layer or quadric-layer film stacks in the gate structure.

摘要:
A semiconductor structure provides lower parasitic capacitance between the gate electrode and contact vias while providing substantially the same level of stress applied by a nitride liner as conventional MOSFETs by reducing the height of the gate electrode and maintaining substantially the same height for the gate spacer. The nitride liner contacts only the outer sidewalls of the gate spacer, while not contacting inner sidewalls, or only a small area of the inner sidewalls of the gate spacer, therefore applying substantially the same level of stress to the channel of the MOSFET as conventional MOSFETs. The volume surrounded by the gate spacer and located above the gate electrode is either filled with a low-k dielectric material or occupied by a cavity having a dielectric constant of substantially 1.0. The reduced height of the gate electrode and the low-k dielectric gate filler or the cavity reduces the parasitic capacitance.
摘要:
A method is provided of forming a conductive via in contact with a bulk semiconductor region of a semiconductor-on-insulator (“SOI”) substrate. A first opening is formed in a conformal layer overlying a trench isolation region. The trench isolation region may share an edge with an SOI layer of the substrate. Desirably, a dielectric layer is deposited over a top surface of the conformal layer and the trench isolation region. A second opening can then be formed which extends through the dielectric layer and the first opening in the conformal layer. Desirably, portions of the bulk semiconductor region and the top surface of the conformal layer are exposed within the second opening. The second opening can then be filled with at least one of a metal or a semiconductor to form a conductive element contacting the exposed portions of the bulk semiconductor region and the top surface of the conformal layer.
