  • Patent number: 8288244
    Abstract: A method for forming a lateral passive device including a dual annular electrode is disclosed. The annular electrodes formed from the method include an anode and a cathode. The annular electrodes allow anode and cathode series resistances to be optimized to the lowest values at a fixed device area. In addition, the parasitic capacitance to a bottom plate (substrate) is greatly reduced.

  • Patent number: 8288821
    Abstract: A structure, and a method for forming the same. The structure includes a semiconductor substrate which includes a top substrate surface, a buried dielectric layer on the top substrate surface, N active semiconductor regions on the buried dielectric layer, N active devices on the N active semiconductor regions, a plurality of dummy regions on the buried dielectric layer, a protection layer on the N active devices and the N active semiconductor regions, but not on the plurality of dummy regions. The N active devices comprise first active regions which comprise a first material. The plurality of dummy regions comprise first dummy regions which comprise the first material. A first pattern density of the first active regions and the first dummy regions is uniform across the structure. A trench in the buried dielectric layer such that side walls of the trench are aligned with the plurality of dummy regions.

  • Patent number: 8234606
    Abstract: An array of through substrate vias (TSVs) is formed through a semiconductor substrate and a contact-via-level dielectric layer thereupon. A metal-wire-level dielectric layer and a line-level metal wiring structure embedded therein are formed directly on the contact-via-level dielectric layer. The line-level metal wiring structure includes cheesing holes that are filled with isolated portions of the metal-wire-level dielectric layer. In one embodiment, the entirety of the cheesing holes is located outside the area of the array of the TSVs to maximize the contact area between the TSVs and the line-level metal wiring structure. In another embodiment, a set of cheesing holes overlying an entirety of seams in the array of TSVs is formed to prevent trapping of any plating solution in the seams of the TSVs during plating to prevent corrosion of the TSVs at the seams.

  • Patent number: 8169007
    Abstract: A junction field effect transistor (JFET) in a semiconductor substrate includes a source region, a drain region, a channel region, an upper gate region, and a lower gate region. The lower gate region is electrically connected to the upper gate region. The upper and lower gate regions control the current flow through the channel region. By performing an ion implantation step that extends the thickness of the source region to a depth greater than the thickness of the drain region, an asymmetric JFET is formed. The extension of depth of the source region relative to the depth of the drain region reduces the length for minority charge carriers to travel through the channel region, reduces the on-resistance of the JFET, and increases the on-current of the JFET, thereby enhancing the overall performance of the JFET without decreasing the allowable Vds or dramatically increasing Voff/Vpinch.

  • Patent number: 8138607
    Abstract: Vertically-staggered-level metal fill structures include inner contiguous metal fill structures and outer contiguous metal fill structures. A dielectric material portion is provided between each contiguous metal fill structure. Vertical extent of each contiguous metal fill structure is limited up to three vertically adjoining metal interconnect levels, thereby limiting the capacitance of each contiguous metal fill structure. Capacitive coupling between the contiguous metal fill structures and the metal interconnect structures is minimized due to the fragmented structure of contiguous metal fill structures.
