    摘要: A metal-insulator-metal capacitor is formed between interconnect layers of an integrated circuit with one of the plates of the capacitor formed integrally with one of the interconnect layers. A dielectric layer is formed on top of the interconnect layer, and a top capacitor plate is formed thereon. A bottom plate is defined by the interconnect layer and extends laterally beyond the top plate so that via interconnects may connect to both plates. An intermetal dielectric (IMD) layer separates the interconnect layer and the capacitor from the next interconnect layer above, and the via interconnects are formed through the IMD layer to connect the above interconnect layer to the capacitor plates. The dielectric layer on top of the interconnect layer that defines the bottom plate and another dielectric layer formed on top of the top plate may serve as etch stops for forming the vias for the via interconnects to different levels.

    摘要: Techniques for fabricating metal-insulator-metal (MIM) capacitive structures by chemical vapor deposition (CVD) help avoid the formation of a porous metal oxide film at the interface between the lower electrode and the insulating layer. One method of fabricating an integrated circuit includes depositing a first titanium nitride electrode layer on a wafer by CVD and subsequently depositing an insulating layer on the first electrode. The insulating layer can comprise a material selected from the group consisting of titanium oxide (TiOx), titanium oxynitride (TiOxNy), titanium oxycarbonitride (TiOxNyCz) and silicon oxide (SiOx), and is deposited by CVD without exposing the first titanium nitride electrode to atmosphere. A second titanium nitride electrode layer also is deposited on the insulating layer by CVD. The various layers of the capacitive structure, including the insulating layer, can be deposited in situ in a single CVD chamber.

    摘要: A process for forming a low k carbon-doped silicon oxide dielectric material (lkc-dsodm) on an integrated circuit structure is characterized by improved planarity and good gap fill in high aspect ratio regions of the integrated circuit structure, as well as improved film strength and adherence, and less byproducts trapped in the film. The process comprises: depositing a plurality of layers of lkc-dsodm on an integrated circuit structure in a reactor; and pausing after depositing each layer of lkc-dsodm and before depositing a further layer of lkc-dsodm. The process can further include first forming a base or barrier layer of a silicon-rich and nitrogen-rich dielectric material over the integrated circuit structure, plasma etching the upper surface of the barrier layer to facilitate adhesion of the subsequently deposited lkc-dsodm to the barrier layer, and then, before depositing the first layer of lkc-dsodm, cooling the etched barrier layer down to within 10° C. or less of the subsequent deposition temperature used for formation of the film of lkc-dsodm. In another aspect of the invention the pausing step further includes, before deposition of the next layer of lkc-dsodm, flowing a source of non-reactive gas over the surface of the newly deposited layer of lkc-dsodm to facilitate outgassing and removal of byproducts resulting from the preceding formation and deposition of lkc-dsodm.

    摘要: A metal-insulator-metal capacitor is embedded in an interconnect layer of an integrated circuit (IC). The interconnect layer has a cavity, and the capacitor is formed in the cavity with one of the plates of the capacitor integral with a conductive layer of the interconnect layer, so the capacitor plate electrically communicates with the interconnect layer. The interconnect layer has multiple conductive layers, including a layer, such as aluminum, that is subject to deformation at certain temperatures during fabrication of the IC, and the cavity extends through this layer. A remaining conductive layer of the interconnect layer defines one of the capacitor plates, and a dielectric layer and another capacitor plate are formed thereon within the cavity. Via interconnects of about the same length electrically connect to the top plate and through the interconnect layer to the bottom plate.

    摘要: A method for forming a bipolar emitter using doped SOG which employs diffusion instead of implanting, and which produces a shallow, low-resistance emitter using a variety of dopants besides boron and phosphorus. A layer of doped SOG is spun over a predefined base region. Portions of the SOG layer are defined for removal and removed, leaving the collector and emitter contact areas exposed. The SOG layer is densified and the dopants are driven into the base to form the emitter.
