Abstract This article focuses on the interaction of infrared (IR) radiation with water droplets. The main objective of the article is the production of water mist in order of evaluation the reduction in intensity of IR radiation. In the experiments described in this paper, a set of five different nozzles was used with various spray characteristics. The respective nozzles were gradually located between the IR radiation source and a detector and the attenuation of IR radiation was assessed. The reduction in IR radiation intensity was determined and IR radiation transmittance was calculated for the respective tested nozzles.

ABSTRACTBoth (100) and (111) Si wafers were implanted with As, P or B to doses from 1013 to 1016/cm2 and annealed with a Varian IA-200 isothermal annealer. The anneal occurs in a vacuum using infrared radiation for exposure times of 5 to 30 sec. Sheet resistance (Rs), Hall effect, RBS and SIMS were used to analyze the wafers. For each dopant a decreasing Rs occurs with increasing exposure time until a minimum value is reached. Longer anneals produce increased dopant diffusion, and the Rs for As and P implanted wafers increased unless the wafer was capped with 0.05 μm of SiO2 which prevents a loss of dopant. The results for (100) wafers are better than for (111) with As doses ≤1015/cm2, however at doses >1015/cm2 the (100) and (111) results are comparable. The As implanted, isothermally annealed layers were thermally stable for As concentrations ≤2E 20/cm3.
