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.
4. Conclusions. Tantalum nitride films were deposited on ceramic substrates (pre-sputtered with underlayer and 100-nm-thick aluminum oxide) by DC reactive magnetron sputtering using a Ta target under a typical base pressure of 10 â7 Torr.
