Plasma-enhanced chemical vapor deposition radio frequency

The radio-frequency glow-discharge method [30-34] has been the most used method in the study of a-C H films. In this chapter, it is referred to as RFPECVD (radio frequency plasma enhanced chemical vapor deposition). Film deposition by RFPECVD is usually performed in a parallel-plate reactor, as shown in Figure 1. The plasma discharge is established between an RF-powered electrode and the other one, which is maintained at ground potential. The hydrocarbon gas or vapor is fed at a controlled flow to the reactor, which is previously evacuated to background pressures below lO"" Torr. The RF power is fed to the substrate electrode...

Thin hexafluoropropylene (HFP) films were deposited applying different reactor conditions by a radio frequency plasma enhanced chemical vapor deposition process onto photolithographic masked silicon surfaces, (a) depicts the crosslink density calculated from ESCA experiments (28). (b) shows the normalized amplitude response. The difference between silicon and HFP response was measured from recorded images allowing for an accurate statistical averaging, and converted into the difference in contact stiffness ks. The SFM measurements were carried in a nitrogen atmosphere (humidity < 4 %) at room temperature. Scan speed was 50 jjm/s, applied lateral modulation amplitude 3.5 nm, and modulation frequency 13 kHz. No external load was applied to the cantilever.
