    摘要: In a disclosed embodiment, a stacked capacitor (100) has bottom, middle and top metal electrode layers (141A, 141B, 141C) interleaved with dielectric layers (142A, 142B) conformally disposed within holes (140A, 140B, 140C) in a protective overcoat or backend dielectric layer (110) over a top metal layer (115) of an integrated circuit (105). A top electrode (155) contacts the top metal electrode layer (141C). A bottom electrode (150) electrically couples an isolated part of the top metal electrode layer (141C) through a bottom electrode via (165A) to a first contact node (135A) in the top metal layer (115) which is in contact with the bottom metal electrode layer (141A). A middle electrode (160) electrically couples a part of the middle metal electrode layer (141B) not covered by the top metal layer (115) through a middle electrode via (165B) to a second contact node (135B) in the top metal electrode layer (115). The sidewalls of the top and middle electrode vias (165A, 165B) are lined with insulating material to electrically isolate the metal electrode layer ends.

    摘要: A junction field-effect transistor (JFET) includes a substrate having a first-type semiconductor surface including a topside surface, and a top gate of a second-type formed in the semiconductor surface. A first-type drain and a first-type source are formed on opposing sides of the top gate. A first deep trench isolation region has an inner first trench wall and an outer first trench wall surrounding the top gate, the drain and the source, and extends vertically to a deep trench depth from the topside surface. A second-type sinker formed in semiconductor surface extends laterally outside the outer first trench wall. The sinker extends vertically from the topside surface to a second-type deep portion which is both below the deep trench depth and laterally inside the inner first trench wall to provide a bottom gate.

A first set of the plurality of features extend from the underlying body to a first plane, and a second set of the plurality features extend from the underlying body to a second plane. A protection layer overlies each of the plurality of features and an isolation layer overlies the underlying body and protection layer, wherein the isolation has a non-uniform first oxide density associated therewith. The isolation layer anisotropically etched based on a predetermined pattern, and then isotropically etched, wherein a second oxide density of the isolation layer is substantially uniform across the workpiece. The predetermined pattern is based, at least in part, on a desired oxide density, a location and extension of the plurality of features to the first and second planes.

    摘要: A one-step CMP process for polishing three or more layer film stacks on a wafer having a multilayer film stack thereon including a silicon nitride (SiNx) layer on its semiconductor surface, and a silicon oxide layer on the SiNx layer, wherein trench access vias extend through the silicon oxide layer and SiNx layer to trenches formed into the semiconductor surface, and wherein a polysilicon layer fills the trench access vias, fills the trenches, and is on the silicon oxide layer. CMP polishes the multilayer film stack with a slurry including slurry particles including at least one of silica and ceria. The CMP provides a removal rate (RR) for the polysilicon layer>a RR for the silicon oxide layer>a RR for the SiNx layer. The CMP process is continued to remove the polysilicon layer, silicon oxide layer and a portion of the SiNx layer to stop on the SiNx layer. Optical endpointing during CMP can provide a predetermined remaining thickness range for the SiNx layer.
