    Notes: Abstract The low-temperature fabrication of silicon nitride films by ArF excimer laser irradiation has been studied. Two fabrication methods are presented. One is photo-enhanced direct nitridation of a silicon surface with NH3 for very thin gate insulators, and the other is photo-enhanced deposition of silicon nitride films with Si2H6 and NH3 gases for stable passivation films. The ArF excimer laser irradiation dissociates the NH3 gas producing NH and NH2 radicals which proved effective in instigating the nitridation reaction. The quality of both films has been much improved and the growth temperature has been lowered by using laser irradiation. These photo-enhanced processes seem to be promising ULSI techniques because they do not depend on high temperatures and are free from possible reactor contamination.

    The expression of matrix metalloproteinases and inhibitors in acute rupture of the anterior cruciate ligament (2000)

    Notes: Abstract Rapid degeneration of the anterior cruciate ligament (ACL) may occur after ligament rupture, making primary repair of the anterior cruciate ligament difficult. Nine completely ruptured anterior cruciate ligaments were collected by arthroscopic surgery performed within 6 months of injury. The authors studied the localization of matrix metalloproteinases and tissue inhibitors of matrix metalloproteinases in ruptured anterior cruciate ligament using immunohistochemistry, and measured messenger ribonucleic acid expression using the reverse transcriptase polymerase chain reaction. Cells in residual ligament tissue seemed to contain matrix metalloproteinases 1 and 3 and tissue inhibitors of matrix metalloproteinases 1 and 2. Promatrix metalloproteinase-9 positive cells were observed in the perivascular area. Promatrix metalloproteinase-2 positive cells frequently were seen between irregular collagen bundles in stumps of ruptured ligaments. Tissue inhibitors of matrix metalloproteinase-2 positive cells commonly were observed in ruptured ligaments. Matrix metalloproteinase-1 and matrix metalloproteinase-3 messenger ribonucleic acid were highly expressed compared with matrix metalloproteinase-2 messenger ribonucleic acid. Tissue inhibitor of matrix metalloproteinase-2 messenger ribonucleic acid was highly expressed compared with tissue inhibitor of matrix metalloproteinase 1. The authors could not identify whether these intrinsic reactions mediated by anterior cruciate ligament cells were the causes of rapid degradation or the results of the degradation process. Various amounts of matrix metalloproteinase and inhibitor production of intrinsic ligament cells were observed in the ruptured anterior cruciate ligament. The biological reaction reported in this study may suggest that pronounced metabolism is undertaken in ruptured ACL cells, and provide useful insight concerning the possiblitiy of achieving the primary repair of ruptured ACL.
