摘要:
An integrated circuit is provided with a semiconductor substrate that is doped with a set concentration of an oxidizable dopant of a type that segregates to the top surface of a suicide when the semiconductor substrate is reacted to form such a silicide. A gate dielectric is on the semiconductor substrate, and a gate is on the gate dielectric. Source/drain junctions are in the semiconductor substrate. A silicide is on the source/drain junctions and dopant is segregated to the top surface of the silicide. The dopant on the top surface of the segregated dopant is oxidized to form an insulating layer of oxidized dopant above the silicide. An interlayer dielectric is above the semiconductor substrate. Contacts and connection points are in the interlayer dielectric to the insulating layer of oxidized dopant above the silicide.

A semiconductor component having analog and logic circuit elements manufactured from an SOI substrate and a method for manufacturing the semiconductor component. An SOI substrate has a support wafer coupled to an active wafer through an insulating material. Openings are formed in the active wafer, extend through the insulating material, and expose portions of the support wafer. Epitaxial semiconductor material is grown on the exposed portions of the support wafer. Analog circuitry is manufactured from the epitaxially grown semiconductor material and high performance logic circuitry is manufactured from the active wafer. The processing steps for manufacturing the analog circuitry are decoupled from the steps for manufacturing the high performance logic circuitry. A substrate contact is made from a portion of the epitaxially grown semiconductor material that is electrically isolated from the portion in which the analog circuitry is manufactured.

A semiconductor device and a method of fabricating thereof, including an insulator layer having alternately layered insulator films and boundary layers, wherein the boundary layers are more dense than the insulator films to prevent expansion and elongation of string-like defects across the boundary layers. The method includes mixing a nitrogen containing gas and a silane group gas to form an insulator film; temporarily stopping a flow of the silane group gas for approximately one to fifteen seconds to form a boundary layer over the insulator film; restarting the flow of the silane group gas; and repeating the steps of temporarily stopping and restarting for a predetermined number of times to form the plurality of alternately layered insulator films and boundary layers. The plurality of alternately layered insulator films and boundary layers is also etched at an etching rate for the insulator films greater than an etching rate for the boundary layers to form a step-shaped sloped opening.

A method for using low dielective SiOF in a process to manufacture semiconductor products, comprising the steps of: obtaining a layer of SiOF; and depleting fluorine from a surface of the SiOF layer. In a preferred embodiment, the depleting step comprises the step of treating the surface of the layer of SiOF with a plasma containing hydrogen. It is further preferred that the treated surface be passivated. The invention also encompasses a semiconductor chip comprising an integrated circuit with at least a first and second layers, and with a dielective layer of SiOF disposed between the layers, wherein the SiOF dielective layer includes a first region at one edge thereof which is depleted of fluorine to a predetermined depth.
