Holliday junctions are important structural intermediates in recombination, viral integration, and DNA repair. We present here the single-crystal structure of the inverted repeat sequence d(CCGGTACCGG) as a Holliday junction at the nominal resolution of 2. 1 A. Unlike the previous crystal structures, this DNA junction has B-DNA arms with all standard(More)
Mobility and Dit distributions for p-channel MOSFETs with HfO2/LaGeOx passivating layers on germanium " Stubborn " triaminotrinitrobenzene: Unusually high chemical stability of a molecular solid to 150 GPa Stress migration risk on electromigration reliability in advanced narrow line copper interconnects Stress migration model for Cu interconnect reliability(More)
Chip-packaging interaction is becoming a critical reliability issue for Cu/low k chips during package assembly. With the traditional TEOS interlevel dielectric being replaced by much weaker low k dielectrics, packaging induced interfacial delamination in low k interconnects has been widely observed, raising serious reliability concerns for Cu/low k chips.(More)
—This paper investigates two key aspects of thermomechanical reliability of through-silicon vias (TSV) in 3D interconnects. One is the piezoresistivity effect induced by the near surface stresses on the charge mobility for p-and n-channel MOSFET devices. The other problem concerns the interfacial delamination induced by thermal stresses including the pop-up(More)

A kinetic analysis was formulated for electromigration enhanced intermetallic evolution of a Cu–Sn diffusion couple in the Sn-based Pb-free solder joints with Cu under bump metallurgy. The simulated diffusion couple comprised the two terminal phases, Cu and Sn, as well as the two intermetallic phases, Cu 3 Sn and Cu 6 Sn 5 , formed between them. The(More)
— The paper describes a 4-MHz temperature compensated reference oscillator based on a capacitive silicon micro-mechanical resonator. The design of the resonator has been optimized to offer large quality factors (22000), while maintaining tunability in excess of 3000ppm for fine tuning and temperature compensation. Oscillations are sustained with a CMOS(More)

Alternating pyrimidine-purine sequences typically form Z-DNA, with the pyrimidines in the anti and purines in the syn conformations. The observation that dC and dT nucleotides can also adopt the syn conformation (i.e. the nucleotides are out-of-alternation) extends the range of sequences that can convert to this left-handed form of DNA. Here, we study the(More)
