  • Patent number: 9865514
    Abstract: A through-silicon via (TSV) capacitive test structure and method of determining TSV depth based on capacitance is disclosed. The TSV capacitive test structure is formed from a plurality of TSV bars that are evenly spaced. A first group of bars are electrically connected to form a first capacitor node, and a second group of bars is electrically connected to form a second capacitor node. The capacitance is measured, and a TSV depth is computed, prior to backside thinning. The computed TSV depth may then be fed to downstream grinding and/or polishing tools to control the backside thinning process such that the semiconductor wafer is thinned such that the backside is flush with the TSV.

  • Patent number: 9496110
    Abstract: Micro-Electro-Mechanical System (MEMS) structures, methods of manufacture and usage, and design structures are disclosed herein. The method includes applying a first voltage polarity to an actuator of a Micro-Electro-Mechanical System (MEMS) structure to place the MEMS structure in a predetermined state for a first operating condition. The method further includes applying a second voltage polarity which is opposite from the first voltage polarity to the actuator of the MEMS structure during a subsequent operating condition.

  • Patent number: 8486796
    Abstract: A method of forming a semiconductor structure includes: forming a resistor over a substrate; forming at least one first contact in contact with the resistor; and forming at least one second contact in contact with the resistor. The resistor is structured and arranged such that current flows from the at least one first contact to the at least one second contact through a central portion of the resistor. The resistor includes at least one extension extending laterally outward from the central portion in a direction parallel to the current flow. The method includes sizing the at least one extension based on a thermal diffusion length of the resistor.

  • 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.
