Polyphenols, the most abundant dietary antioxidants, also possess many other anticarcinogenic activities. Urinary metabolites of polyphenols could complement dietary assessment of the bioavailability of these nutrients. We conducted a study of 353 incident breast cancer cases and 701 individually matched controls nested within the Shanghai Women’s Health Study cohort of women aged 40–70 years at baseline...
This paper presents the results obtained from an experimental study of the impact of modern process technologies on the electrical parameters of interconnects. Variations in parasitic capacitances and resistances due to dummy metal fills, chemical mechanical polishing, multiple thin inter-layer dielectrics and trapezoidal conductor cross-sections are presented. Accurate variations in the parasitics...
Thickness range, i.e. the difference between the highest point and the lowest point of the chip surface, is a key indicator of chip yield. This paper presents a novel metal filling algorithm that seeks to minimize the thickness range of the chip surface during the copper damascene process. The proposed solution considers the physical mechanisms in the damascene process, namely ECP (which is the process...
