A new volatility model: GQARCH‐ItÔ model

Huiling Yuan, Yulei Sun, Lu Xu, Yong Zhou, more

Journal of Time Series Analysis > 43 > 3 > 345 - 370

Volatility asymmetry is a hot topic in high‐frequency financial market. This article proposes a new econometric model, which could describe volatility asymmetry based on high‐frequency data and low‐frequency data. After providing the quasi‐maximum likelihood estimators for the parameters, we establish their asymptotic properties. We also conduct a series of simulation studies to check the finite sample...

A multi-step wafer-level run-to-run controller with sampled measurements for furnace deposition and CMP process flows: APC: Advanced process control

Yulei Sun, Joerg Reichelt, Tilo Bormann, Andreas Gondorf

2016 27th Annual SEMI Advanced Semiconductor Manufacturing Conference (ASMC) > 399 - 402

2016 27th Annual SEMI Advanced Semiconductor Manufacturing Conference (ASMC)

This paper describes a multi-step Run-to-Run controller design for a class of furnace deposition and CMP process flows. The wafer-to-wafer thickness variation introduced by the furnace deposition process has been compensated for by a wafer-level CMP controller. To avoid measuring all wafers in a lot and to reduce metrology cost, knowledge of upstream furnace process was employed and a piecewise linear...

Chinese Science Bulletin > 2013 > 58 > 33 > 4084-4091

Bacterial artificial chromosomes (BACs) or yeast artificial chromosomes (YACs) containing large inserts as probes for fluorescence in situ hybridization (FISH) have been used in the physical mapping of specific DNA sequences, especially for single- or low-copy sequences. Our earlier study identified Stpk-V, a powdery mildew resistance-related gene located on the 6VS chromosome arm of the wild grass...
