초록
This paper describes the particle-initiated breakdown characteristics of various spacers, which have a ribbed surface, in the presence of a metallic particle. The particles was attached on the surface of each spacer. The breakdown voltages were measured by changing the particle position on the spacer, the length and thickness of the rib. Also the electrical field analyses were performed. As a result, the breakdown voltage of the spacer with two ribs was highest, and it was varied by the length and the thickness of the rib. Especially, in case of the rib with round edge the breakdown voltage was higher than that with rectangular edge, which complied with the result through the field analysis.
