Dose Calibration of Ion Implanters for Semiconductor Production

February 1, 1998
Author(s)
F A. Stevie, David S. Simons, J M. McKinley, J McMacken, R Santiesteban, P Flatch, J Becerro
Absolute dose calibration is important for process simulation and transfer of manufacturing to different production line or locations, but until recently, no viable standards were available. With the creation of a NIST standard for boron, it is now

Fault Classes and Error Detection in Specification Based Testing

February 1, 1998
Author(s)
David R. Kuhn
Specification based testing relies upon methods for generating test cases from predicates in a software specification. These methods derive various test conditions from logic expressions, with the aim of detecting different types of faults. Some authors

Magneto-Optical Trapping of Fermionic Potassium Atoms

February 1, 1998
Author(s)
F S. Cataliotti, Eric A. Cornell, C Fort, M Inguscio, F Marin, M Prevedelli, G M. Tino
We have trapped 40K in a vapor-cell magneto-optical trap starting from a natural abundance sample. This rare, weakly radioactive atom is a Fermion. The number of trapped atoms is approximately 8000 with a density of approximately equal to} 10 8 atoms/cm 3

Metallurgy of the RMS Titanic

February 1, 1998
Author(s)
Timothy J. Foecke
Metallurgical and mechanical analyses were performed on steel and rivet samples recovered from the wreck of the RMS Titanic. It was found that the steel possessed a ductile-to-brittle transition temperature that was very high for this type of steel, making
