Seedless electroplating on patterned silicon
Nickel thin films have been electrodeposited without the use of an additional seed layer, on highly doped silicon wafers. These substrates conduct sufficiently well to allow deposition using a peripherical electrical contact on the wafer. Films 2 μm thick have been deposited using a nickel sulfamate bath on both n+and p+-type silicon wafers, where a series of trenches with different widths had ...

متن کاملBeryllium and Beryllium Compounds
Beryllium (atomic number, 4; relative atomic mass, 9.01) is a metal, which belongs to Group IIA of the Periodic Table. The oxidation state of beryllium compounds is +2. Selected chemical and physical properties of beryllium, beryllium– aluminium and beryllium–copper alloys, and various beryllium compounds can be found in the previous IARC Monograph (IARC, 1993). Beryllium is the lightest of all...

compared with those ofboth the general population and a cohort of viscose-rayon workers. Ratios of observed to expected deaths for lung cancer in the two industrial populations (65 observed) were found to be elevated in both comparisons (1.4 in respect of both the general population (95% confidence interval (CI), 1. 1 1.8) and the viscose-rayon workers (1.0-2.0)) and tended to be concentrated i...
