Electroplated Ni/Au over Cu is a popular metallization for printed circuit board (PCB) finish as well as for component leads, especially for wire-bondable high frequency packages, where the gold thickness requirement is high (≥ 20 µinches) for wire bonding. This study examines the effect of redeposition of bulk AuSn4 IMC as a function of varying gold content (2–5 nominal weight-%) in the solder joint...
Highly crystalline silicon carbide films were synthesised by HWCVD technique. Raman spectroscopic studies show that the SiC films contain crystalline SiC and also carbon phases. Carbon is graphitic at higher chamber pressures (≥50 Pa) and resembles diamond-like carbon at low pressure (5 Pa). Cross-section TEM results show a columnar morphology of the crystallites with typical column diameters up to...
The effect of varying filament and substrate temperatures on the structure and electrical conductivity of crystalline SiC films prepared by HWCVD technique are described in this paper. At a constant filament temperature, the electrical conductivity of the SiC films increases with increasing substrate temperature. However, TEM studies show that there is no change in the size of the SiC columnar grains...
