  • Patent number: 8965550
    Abstract: A wafer fabrication outcome, such as wafer yield or wafer lifetime, is predicted by excluding uncontrollable but measurable internal/external noises of a DOE system, and by rendering relations between wafer design variables and wafer outcome outputs to be more causal, as well as the relations between variances for each of the wafer design variables and the wafer outcome outputs. With the aid of a wafer fabrication outcome predicting model formed by the more causal relations, precision of predicting wafer outcomes can be raised, and performance of wafer fabrication can be thus raised as a result.

  • Patent number: 8852657
    Abstract: The identification and isolation of chromones and novel chromone compositions from plant sources that exhibit up-regulation of adiponectin production by adipocytes and the normalization of virtually hundreds of genes related to glucose and fatty acid metabolic and signaling pathways. The chromone compositions are effective in enhancing adiponectin production by adipocytes and regulating genes involved in fatty acid biosynthesis, mitochondrial ?-oxidation of fatty acids, steroid biosynthesis, gluconeogenesis, fat transport, PPAR?/RXR? liver signaling and xenobiotic metabolism. The chromone compositions can be used to increase insulin sensitivity, improve glucose tolerance, lower triglyceride levels and balance glucose levels in mammals. Included are methods for the prevention and treatment of a variety of diseases and conditions including, but not limited to insulin resistance, glucose intolerance, hyperglycemia, metabolic syndromes, dyslipidemia, and hypertriglyceridemia.

  • Publication number: 20140089871
    Abstract: For improving wafer fabrication, yield and lifetime of wafers are predicted by determining coefficients of a yield domain for wafer yield prediction and a lifetime domain for a wafer lifetime prediction, an integral domain, an electric/layout domain, a metrology/defect domain, and a machine sensor domain in a hierarchical manner. With the aid of the hierarchically-determined coefficients, noises in prediction can be reduced so that precision of prediction results of the yields or the lifetimes of wafers can be raised.

  • Patent number: 7928773
    Abstract: Generation of multiple clocks having a synchronized phase relationship may reduce the size, complexity, power consumption, jitter and cost of circuitry while improving its functionality, performance, reliability and fault coverage. A multiple frequency clock generator may comprise an independent digital control oscillator (DCO) for generating a first clock and dependent DCOs for generating additional clocks that align at a common multiple frequency with the first clock with or without adjustment thereof. The independent and dependent DCOs may generate the first and additional clocks from a delay lock loop (DLL) by selecting a sequence of tap select signals. Tap select signals may be adjusted to maintain a desired phase and/or frequency of the first and additional clocks. Dependent DCOs may generate sequences of tap select signals based on the sequence of tap select signals generated by the independent DCO to incorporate adjustments, e.g., PLL error corrections.
