Comparative Study of Experimental Techniques for Boron Profiling at Poly-Si/SiO2 Interface
Electrical characterization of MOS structures and device modeling require accurate information about dopant concentration, particularly at the poly-Si/SiO2 interface. We compare four experimental techniques (seco...

Boron Diffusion in Si1-x Gex Strained Layers
Boron diffusion in Sia7 Gea3 strained layers has been studied as a function of annealing temperature and is compared to boron diffusion in unstrained Si epitaxial layers. A lower diffusivity was observed in Sia7 ...

Passivating Complexes in Cd Doped GaAs and InP: Microscopic Properties and Electrical Effects
Perturbed Angular Correlation (PAC) and Hall measurements were used to investigate the stability of the passivating Cd-H complex in GaAs after low energy H implantation (150 eV, 1014 cm−2) at 300 K. From the obse...

Early Detection of Gastrointestinal Cancers: Recent Progress in Endoscopy and Surgical Results
Because Japan is a country with a very high risk of gastric cancer, its early detection has been a leading, nationwide project of cancer control. As a result, early diagnosis, particularly that achieved by end...

Ion-Implantation Effects on Spin-on-Glass (Sol-Gel) SiO2 Films
Silicon and phosphorus ions were implanted into Spin-On-Glass (Sol-Gel) SiO2 films and were found to modify the material properties. Two SOG types, polysiloxane andsilicate, were ion-implanted with doses in the 5...

Role of Langerhans cells in epidermotropism of T cells
Certain T lymphocytes display a specific affinity for the epidermis (epidermotropism). Recent studies have suggested that Ia+ Langerhans cells (LCs) are possible targets for the epidermotropism. A variety of self...

Effects of Si Implantation on Sb Diffusion In Sb-Silica Spin-On Layers
The effects of Si implantation (2×1015 • cm−2) on the diffusion of Sb in Sb doped silica (SiO2) spin-on layers and on their hardness were studied. RBS analysis and AES depth profiling showed that the implantation...
