From a dielectric integration standpoint , the most notable difference between the
two approaches is the need for dielectric gapfill following subtractive metal etch
as compared with the use of planar dielectric deposition in the damascene ...

RESULTS AND DISCUSSION Deposition Rates Figure 1 shows the deposition
rates per pulse cycle for CH2F2 , C2H2F4 , CHCIF2 , and HFPO as a function of
pulse off time for a constant pulse on time of 10 ms . All four precursors show an ...
