Based on the elastic plasticity contact analysis theory and the plastic damage yield criterion, a mechanical model of the slip-drilling pipe is established. After studying their plastic deformation and drilling pipe's sliding, optimization of the slip dog's structure has been proposed. In the light of the systems of different specifications of drilling(More)
InSbN alloys are the new narrow bandgap semiconductors capable of broadband and long wavelength infrared photodetection. This paper reports the annealing conditions on the properties and quality of InSbN alloys, fabricated by multi-step ion implantation. The InSbN samples were annealed at different annealing methods, temperatures, and periods of time. They(More)
Three advanced direct contact via processes with Ta/TaN/Ta tri-layer barrier and the electromigration of their structures were comparatively investigated. The process of Ar<sup>+</sup> resputtering with median removal of tri-layer barrier shows the lowest defective die percentage. It also shows the highest activation energy and longest downstream(More)
Accurate pore pressure prediction is a necessary requirement to well structure optimizing, drilling difficulty minimizing, drilling accidents preventing. It plays a very important role in the economically and efficiently well operating. Previous methods for pore prediction have their own hypothesizes and cannot take into consideration factors that indicate(More)
We report the effect of a Ta/TaN/SiCN tri-layer barrier on the electrical properties and thermal stability of single damascene (SD) lines for Cu-ultra low k (2.3) integration. It was found that by incorporating a thin SiCN layer between the Ta/TaN barrier and ultra low k material, the leakage current can be significantly reduced and the breakdown voltage(More)
