We describe interconnect features for Intel's 22nm high-performance logic technology, with metal-insulator-metal capacitors and nine layers of interconnects. Metal-1 through Metal-6 feature a new ultra-low-k carbon doped oxide (CDO) and a low-k etch stop. Metal-7 and Metal-8 use a low-k CDO. New materials and process optimization provide 13–18% capacitance improvement. Single-exposure patterning for...
Improper fitting of helix bundle to rod and rod to barren envelope leads to high thermal resistances and hence restricts average power handling capability of a TWT. In this paper, authors have calculated thermal resistances at different joints of a helix traveling-wave tube (TWT), analytically and validated with COSMOS software.
Yield enhancements in the manufacturing process today require an expensive, long and tedious physical failure analysis process to identify the root cause. In this paper we present Axiom, a new technique geared towards efficiently identifying a single dominant defect mechanism (for example in an excursion wafer) by analyzing fail data collected from the production test environment. Axiom utilizes statistical...
Rain-water samples were collected from Jaipur and Kota in Western India during the monsoon seasons of 1996-1999. In all cases, the pH of rain-water samples exceeded 7.0 and fell in the range (7.1-8.5). In view of the fact that the trace metals particularly iron, manganese and copper have been held responsible for the catalytic activity of rain-water, the chemical analysis of the collected samples...
