You might be confused to see Cafe 125 listed on your W-2 form. This may sound like it has something to do with where you go on your lunch break, but there is a more reasonable explanation. Cafe 125 stands for IRS regulation code section 125 regarding tax-free cafeteria plans.
The tantalum nitride films consist of a mixture of metallic tantalum, Î²-TaN 0.05, Î³-Ta 2 N and cubic/hexagonal TaN phases, their composition depending on both the ion dose and ion energy. 13. The kinetics of nitridation is characterised by two stages.
As the nitrogen ion dose increases, an attenuation of the metallic Ta 0 doublet at ~21.7eV and the growth of a new broad band in the high binding energy side associated with the formation of tantalum nitride are observed.
