Abstract

A hybrid plasma system with combination of ac and microwave at atmospheric pressure was developed. The hybrid plasma is initiated by ac capillary plasma, is stabilized by a flowing channel of working gas through common electrodes, and is expanded by the dissipation of microwave energy, revealing two distinguishable plasma columns of about 1 m in length and a transition point. The capillary in the hybrid plasma system is working as a common electrode for the microwave and ac plasmas. Optical emission spectroscopy is used to characterize and monitor the argon and nitrogen excited species produced in different plasma columns.

Nonequilibrium atmospheric pressure plasma jet using a combination of 50 kHz/2 MHz dual-frequency power sources

Journal Article Zhou, Yong-Jie ; Yuan, Qiang-Hua ; Li, Fei ; ... - Physics of Plasmas

An atmospheric pressure plasma jet is generated by dual sinusoidal wave (50 kHz and 2 MHz). The dual-frequency plasma jet exhibits the advantages of both low frequency and radio frequency plasmas, namely, the long plasma plume and the high electron density. The radio frequency ignition voltage can be reduced significantly by using dual-frequency excitation compared to the conventional radio frequency without the aid of the low frequency excitation source. A larger operating range of α mode discharge can be obtained using dual-frequency excitation which is important to obtain homogeneous and low-temperature plasma. A larger controllable range of the gas temperaturemore »« less

A pulse-modulated nonequilibrium atmospheric-pressure microwave argon plasma discharge preionized by a kilohertz excited plasma jet

Journal Article Li Shouzhe ; Xu Maochun ; Zhang Xin ; ... - Applied Physics Letters

A pulse-modulated nonequilibrium atmospheric-pressure microwave argon surface wave plasma is generated by means of a preionization discharge with a single-electrode plasma jet driven by a power supply of 50 kHz. It is found that the electron induced Saha-like balance dominates excitation process in the plasma discharge through the electron temperature varying with the microwave input power and the applied voltage of kilohertz power supply. The microwave pulse-modulating effect on nonequilibrium characteristics of dual-frequency exciting argon surface wave plasma is studied by spectroscopic measurement of the excitation temperature and gas temperature.

Ultrahigh-speed etching of SiO{sub 2} with ultrahigh selectivity over Si in microwave-excited non equilibrium atmospheric pressure plasma

Journal Article Yamakawa, Koji ; Hori, Masaru ; Goto, Toshio ; ... - Applied Physics Letters

Etching of a SiO{sub 2} film [Boro-phospho silicate glass (BPSG)] has been performed in a continuous-wave microwave-excited nonequilibrium atmospheric pressure plasma using a microgap discharge. A NF{sub 3}/He gas mixture with added H{sub 2}O was employed as the feed gas. An ultrahigh etch rate for SiO{sub 2} (BPSG) of 14 {mu}m/min and an ultrahigh selectivity over Si(SiO{sub 2}/Si) of 200 was obtained. A mechanism for the selective etching is proposed based on results obtained using Fourier transform infrared spectroscopy and spatially imaged optical emission spectroscopy with an intensified charge-coupled device camera. This process could offer a breakthrough for ultrahigh-speed, damage-freemore »« less

Properties of atmospheric pressure plasmas with microwave excitations for plasma processing

Journal Article Nagai, Mikio ; Hori, Masaru ; Goto, Toshio - Journal of Vacuum Science and Technology. A, Vacuum, Surfaces and Films

Atmospheric pressure plasmas with microwave excitations were successfully produced in dielectric barrier micro plasmas employing N{sub 2}, Ar, or He gas. N{sub 2} optical emissions of the second positive system were measured for evaluating the gas temperature. The gas temperatures of the plasmas could be much less than 1000 K. Blackbody emissions were measured by Fourier transform infrared spectrometer for evaluating the electrode temperature. Temperatures of both the gas and electrode were evaluated by fitting the experimental results with calculations. The gas temperature in the N{sub 2} plasma was notably increased with the discharge time as compared with those inmore »« less

Role of dissociative recombination in the excitation kinetics of an argon microwave plasma at atmospheric pressure

Journal Article Sainz, A. ; Margot, J. ; Garcia, M.C. ; ... - Journal of Applied Physics

A collisional radiative model was developed in order to investigate the influence of dissociative recombination on the Saha-Boltzmann plasma equilibrium. As the dissociative recombination products are not well known, their relative importance was tested through comparison with the distribution of line intensities obtained in a microwave argon discharge produced at atmospheric pressure by a surface wave. It was found that the main dissociation products are the ground state and the 4s levels, the 5p and upper levels playing a negligible role. Because the higher levels are only weakly affected by dissociative recombination, they remain in partial local thermodynamic equilibrium. Therefore,more »« less
