    摘要: It has been discovered that for semiconductor devices such as MOSFETs, there is significant capacitive coupling in the front-end structure, i.e., the structure from and including the device substrate up to the first metal interconnect level. The invention therefore provides a device comprising a silicon substrate, an isolation structure in the substrate (e.g., shallow trench isolation), an active device structure (e.g., a transistor structure), a dielectric layer over the active device structure, and a metal interconnect layer over the dielectric layer (metal-1 level). At least one of the dielectric components of the front-end structure comprise a material exhibiting a dielectric constant less than 3.5. This relatively low dielectric constant material reduces capacitive coupling in the front-end structure, thereby providing improved properties in the device.

    摘要: The invention is a process for device fabrication that utilizes shallow trench isolation. The process involves the steps of forming an oxidation barrier region, e.g., silicon nitride, above a silicon substrate, providing an opening in the oxidation barrier region and in any underlying regions deposited on the silicon, providing a trench in the silicon substrate at the opening, depositing a dielectric material such as silicon dioxide in the trench, typically planarizing the trench silicon dioxide, and subsequently performing an oxidation step. The oxidation step rounds the otherwise sharp corners of the silicon at the area where the trench silicon dioxide meets the pad oxide. The invention thereby reduces or eliminates sharp corners that contribute to leakage current.

    摘要: Ion beam deposition, using a carbon- and fluorine-containing source or sources, is used to form a fluorinated diamond-like carbon layer in a device, the FDLC layer exhibiting a dielectric constant of 3.0 or less along with a thermal stability of at least 400° C. During the ion beam deposition, due to the unique nature of carbon chemistry, the carbon atoms combine at the substrate surface to form all possible combinations of sp1, sp2 and sp3 bonds. However, ion beam etching occurs along with deposition, such that atoms of the weaker carbon structures—carbyne and graphite—are removed preferentially. This leads to a buildup of a diamond-like, sp3-bonded structure with fluorine atoms, it is believed, substituted for some carbon atoms within the structure, this structure providing the desirable properties of the layer.

    摘要: The invention provides a device containing a low .kappa., hydrogen-free a-C:F layer with good adhesion and thermal stability. It was found that the combination of desirable properties was attainable by a relatively easy process, as compared to processes that utilize gaseous sources, such as CVD. Specifically, the a-C:F layer is formed by sputter deposition, using only solid sources for the fluorine and carbon, and in the absence of any intentionally-added hydrogen-containing source. The sputtering is performed such that the layer contains 20 to 60 at. % fluorine, and also, advantageously, such that the a-C:F exhibits a bandgap of about 2.0 eV or greater. The a-C:F layer formed by the process of the invention exhibits a dielectric constant, at 1 MHz and room temperature, of 3.0 or less, advantageously 2.5 or less, and more advantageously 2.1 or less, along with being thermally stable up to at least 350.degree.

    摘要: A process for fabricating an integrated semiconductor device with a low dielectric constant material and an integrated semiconductor device with the low dielectric constant material interposed between two conductors is disclosed. The low dielectric constant material has a dielectric constant of less than about 2.8. The low dielectric constant material is a porous glass material with an average pore size of less than about 10 nm. The low dielectric constant material is formed on a semiconductor substrate with circuit lines thereover by combining an uncured and unmodified glass resin with an amphiphilic block copolymer. The amphiphilic block copolymer is miscible in the uncured glass resin. The mixture is applied onto the semiconductor substrate and the glass resin is cured. The glass resin is further processed to decompose or otherwise remove residual block copolymer from the cured glass resin.

    摘要: Integrated circuits employing titanium nitride are significantly improved by using a specific method for formation of the titanium nitride in the device fabrication. In particular, a plasma such as one formed in an electron cyclotron resonance apparatus is employed to dissociate a source of nitrogen and a source of hydrogen and the dissociation products are combined at the integrated circuit deposition substrate with titanium tetrachloride. The resulting deposition is essentially devoid of chlorine and has advantageous step-coverage properties.
