    1993-8-15Fig. 5 shows the spectra obtained with the source placed in the middle of the chamber, 11 cm from the grid, with and without a plastic absorber 2 mm thick placed in front of the source to stop the electrons. The drift field is 90 V cm-bar- and the sense wire and field wire high voltages are 4400 V and 500 V respec- tively.Cited by: 5

    1997-1-21Fig. 6 contains the data taken with CF4. Both graphs also show the simulated data. In these graphs we can see that the pressure has a negative influence on the gain of the MSGC. We also observe that the gain at high pressure in isobutane becomes less than the gain in CF4. In the graphs also the results for different bias voltages

  • Angular dependences of SiO2 etch rates at different bias

    2017-9-1The angular dependences of SiO 2 etch rates at different bias voltages for in CF 4, C 2 F 6, and C 4 F 8 plasmas were investigated using a Faraday cage system. When the bias voltage was − 400 V, the normalized etch yields (NEYs) reached a maximum at 70& in CF 4 and C 2 F 6 plasmas, while they decreased monotonicallyCited by: 5

    Measurements were performed in Ar and in CF4/Ar mixtures. For biasing supply operating at low frequency, 700 kHz, it was shown that the effect of the voltage becomes significantly smaller as the sustaining voltage is changed from high frequency, 13.56 MHz, to very high frequency (VHF), 100 MHz, and it even

  • Techniques to Generate High Voltages - UKEssays.com

    High AC voltages are frequently used in transmitting and distribution lines due to being relatively easier to transport over long distances, at high voltages less energy is lost in the transmission. They are very useful as the voltage levels can be stepped up or down by using transformers in the means of induction.

  • CF4/O2 Plasma Etching of Polymers | SpringerLink

    Abstract. CF 4 /O 2 plasmas have been used to etch a variety of polymers (PPE, PS, PMMA, PC). Purely hydrocarbon polymers (PPE and PS) are etched less readily than oxygen containing polymers (PMMA and PC). The application of bias voltages to polymer samples resulted in an increase of the number and energy of ionsAuthor: E. Occhiello, M. Morra, F. Garbassi
