Depth Profile Analysis

Comparison of SIMS (top) and GD-MS (bottom) analyses on sample R6-2b (implanted B). dc HR-GD-MS can be used for depth profile analysis of impurities in PV Si with good sensitivity and a depth resolution of 0.5 μm. Concentration profiles of samples contaminated with B, P and Ti agreed well with implanted levels. For fast diffusing transition elements, e.g. Fe and Cu, different impurity distribution mechanisms occur. This should be taken into account when analysing these impurities.

Diamond Potential

IR spectroscopy was used to compare diamonds from 12 pipes, Arkhangelsk region. Based on positive correlation between average N and H values in diamonds from various deposits, it was found that crystals from low-grade diamond pipes are relatively enriched in hydrogen compared with diamonds from Lomonosov and Grib deposits. In terms of structural impurity distribution, Arkhangelsk deposit diamonds differ from Yakutian diamonds; it could be due to various composition of compared diamonds’ source matter and thermodynamic conditions of their growth. It is shown that hydrogen is a negative factor of diamond potential in both Yakutian and Arkhangelsk diamonds. This can partly be explained by impuri-ty blocking effect on diamond crystal growth.

And Diffusion

The ProENGINEER software is used to build a geometric model for the whole process cavity and internal structure and conduct the internal dynamic simulation of cavity with different diffusion temperatures of 1,000°C, 1,050°C, 1,100°C and 1,150°C, and different diffusion time of 5 min, 10 min, 15 min and 20 min. Analyze the process control indexes by combining with specific thermal diffusion test, and study the relationship between hydrodynamic parameters and diffusion uniformity, Comprehensively investigate the effects of the diffusion temperature and diffusion time on doping, achieving the requirements of impurity distribution in materials.
