Abstract

The invention concerns a system of electrodes for generating a surface dielectric barrier discharge totally encapsulated in a ceramic dielectric, using co-fireable ceramic technology (ceramic tapes, LTCC, HTCC, green tapes). The plasma generation device can be built not only flat but also curved, for integration on flat or curved surfaces of any material, even metallic. The system can sustain voltages of the order of 1OkV or higher, and can be run continuously for very long times thanks to its high thermal and chemical resistance (typically several tens of hours). More specifically, the system can generate plasmas in gases, including air, at atmospheric pressures down to pressures of about 0.1 bars. The plasma can also be sustained in high speed gas flows, up to Mach 1.2. This aspect allows the system to be used for airflow control or plasma-aided combustion in addition to the surface or gas treatment applications.

Plasma etching

Plasma etching is a form of plasma processing used to fabricate integrated circuits. It involves a high-speed stream of glow discharge (plasma) of an appropriate gas mixture being shot (in pulses) at a sample. The plasma source, known as etch species, can be either charged (ions) or neutral (atoms and radicals). During the process, the plasma generates volatile etch products at room temperature from the chemical reactions between the elements of the material etched and the reactive species generated by the plasma.

Generation

A generation refers to all of the people born and living at about the same time, regarded collectively. It can also be described as, "the average period, generally considered to be about 20–⁠30 years, during which children are born and grow up, become adults, and begin to have children." In kinship terminology, it is a structural term designating the parent-child relationship. It is known as biogenesis, reproduction, or procreation in the biological sciences.

Greatest Generation

The Greatest Generation, also known as the G.I. Generation and the World War II generation, is the Western demographic cohort following the Lost Generation and preceding the Silent Generation. The generation is generally defined as people born from 1901 to 1927. They were shaped by the Great Depression and were the primary generation composing the enlisted forces in World War II. Most people of the Greatest Generation are the parents of the Silent Generation and Baby Boomers, and, in turn, were the children of the Lost Generation.
