✦ Synopsis

The authors investigated carbon formation during steamcracking of cyclohexane, toluene and n-hexane. The kinetic study of deposition and the observation of deposits by electron microscopy show that carbonaceous materials may be formed as follows: (1) In the case of cyclohexane and toluene, the initial hydrocarbon reacts in the gas phase and forms hydrocarbon species which condense into droplets, striking substrate on which they solidify (dehydrogenation). (2) In the case of n hexane, the hydrocarbon yields gaseous intermediate species which react on the substrate and form carbonaceous products 1. INTRODUCTlON

This paper describes a contact degradation mechanism during window formation followed by selective tungsten chemical vapor deposition (W-CVD). Contact resistances by using selective W-CVD were increased as the overetching rate increased. Surface analysis made it clear that the Si surface at the bott
