  • Patent number: 11955425
    Abstract: Interconnect structures that maximize integrated circuit (IC) density and corresponding formation techniques are disclosed. An exemplary IC device includes a gate layer extending along a first direction. An interconnect structure disposed over the gate layer includes odd-numbered interconnect routing layers oriented along a second direction that is substantially perpendicular to the first direction and even-numbered interconnect routing layers oriented along a third direction that is substantially parallel to the first direction. In some implementations, a ratio of a gate pitch of the gate layer to a pitch of a first of the even-numbered interconnect routing layers to a pitch of a third of the even-numbered interconnect routing layers is 3:2:4. In some implementations, a pitch of a first of the odd-numbered interconnect routing layers to a pitch of a third of the odd-numbered interconnect routing layers to a pitch of a seventh of the odd-numbered interconnect routing layers is 1:1:2.

    Abstract: An integrated circuit includes a first standard cell having a first pFET and a first nFET integrated, and having a first dielectric gate on a first standard cell boundary. The integrated circuit further includes a second standard cell being adjacent to the first standard cell, having a second pFET and a second nFET integrated, and having a second dielectric gate on a second standard cell boundary. The integrated circuit also includes a first filler cell configured between the first and second standard cells, and spanning from the first dielectric gate to the second dielectric gate. The first pFET and the second pFET are formed on a first continuous active region. The first nFET and the second nFET are formed on a second continuous active region.

  • Publication number: 20110177612
    Abstract: The present invention relates to methods of identifying whether a candidate compound is a modulator of a G protein-coupled receptor (GPCR). In preferred embodiments, the GPCR is human. In other preferred embodiments, the GPCR is coupled to Gi and lowers the level of intracellular cAMP. In other preferred embodiments, the GPCR is expressed endogenously by adipocytes. In further preferred embodiments, the GPCR inhibits intracellular lipolysis. In other further preferred embodiments, the GPCR is a nicotinic acid receptor. The present invention also relates to methods of using a modulator of said GPCR. Preferred modulator is agonist. Agonists of the invention are useful as therapeutic agents for the prevention or treatment of metabolic-related disorders, including dyslipidemia, atherosclerosis, coronary heart disease, stroke, insulin resistance, and type 2 diabetes.

  • Patent number: 6485919
    Abstract: In accordance with the present invention, there are provided nucleic acids encoding human metabotropic glutamate receptor subtypes and the proteins encoded thereby. In a particular embodiment, the invention nucleic acids encode mGluR1, mGluR2, mGluR3 and mGluR5 subtypes of human metabotropic glutamate receptors. In addition to being useful for the production of metabotropic glutamate receptor subtypes, these nucleic acids are also useful as probes, thus enabling those skilled in the art, without undue experimentation, to identify and isolate related human receptor subunits. In addition to disclosing novel metabotropic glutamate receptor subtypes, the present invention also comprises methods for using such receptor subtypes to identify and characterize compounds which affect the function of such receptors, e.g., agonists, antagonists, and modulators of glutamate receptor function.
